CDC and ADA Now Advise to Avoid Using Fluoride

[amazon_link asins=’B00006FXPB,B01CDA3A5Q,B01MY0XNZT,B01M3UB8IM,B01N6A7O05′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’06622f52-f59c-11e6-a06f-49d7f942a43e’]

It was 2007 when the American Dental Association (ADA) first warned that parents of infants younger than a year old “should consider using water that has no or low levels of fluoride” when mixing baby formula, due to concerns about fluorosis.

Now the Journal of the American Dental Association has published a study that found increased fluorosis risk among infants who were fed infant formula reconstituted with fluoride-containing water, as well as used fluoridated toothpastes.

A new study in the Journal of the American Dental Association finds once again that, contrary to what most people have been told, fluoride is actually bad for teeth.

Exposure to high levels of fluoride results in a condition known as fluorosis, in which tooth enamel becomes discolored. The condition can eventually lead to badly damaged teeth. The new study found that fluoride intake during a child’s first few years of life is significantly associated with fluorosis, and warned against using fluoridated water in infant formula.

The Centers for Disease Control and Prevention (CDC) is of a similar opinion. According to their website:

“Recent evidence suggests that mixing powdered or liquid infant formula concentrate with fluoridated water on a regular basis may increase the chance of a child developing … enamel fluorosis.”

Eat Mouth-Healthy for Healthy Teeth

[amazon_link asins=’B000KEVF32,B001797XPI,B00L9VHBX8,B01DSKKZ2G,B00B5RFPYS,B00755O9ZA’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’3a3867da-c506-11e7-96dc-8347bd655d01′]

If you want to prevent cavities, how often you eat can be just as important as what you eat. That’s because food affects your teeth and mouth long after you swallow. Eating cookies with dinner will do less harm to your teeth than eating them as a separate snack. Of course, overall poor nutrition can contribute to periodontal (gum) disease. It also can have other long-term effects on your mouth. Learning how food affects your oral health is the first step toward mouth-healthy eating.

Immediate Effects of Food
Changes begin in your mouth the minute you start to eat certain foods. Bacteria in your mouth make acids. The acids start the process that can lead to cavities.

How does this happen?
All carbohydrate foods eventually break down into simple sugars: glucose, fructose, maltose and lactose. Fermentable carbohydrates break down in the mouth. Other foods don’t break down until they move further down the digestive tract.

It’s the fermentable carbohydrates that work with bacteria to form acids that begin the decay process and eventually destroy teeth. They include the obvious sugary foods, such as cookies, cakes, soft drinks and candy. But they also include less obvious foods, such as bread, crackers, bananas and breakfast cereals.

Certain bacteria on your teeth use the sugars from these foods and produce acids. The acids dissolve minerals inside the tooth enamel. The process is called demineralization. Teeth also can regain minerals. This natural process is called remineralization. Saliva helps minerals to build back up in teeth. So do fluoride and some foods.

Dental decay begins inside the tooth enamel when minerals are being lost faster than they are being regained.

The longer food stays near the bacteria on the tooth, the more acids will be produced. So sticky carbohydrates, such as raisins, can do more acid damage. But other foods that pack into crevices in the tooth also can cause decay. Potato chips are a terrific example. Eat a handful of chips and see how long you have to work to get all the stuck bits out from between your teeth. Teeth with a lot of nooks and crannies, such as molars, are more likely to trap food. That’s why they tend to have more decay.

To make matters worse, many of the foods that are unhealthy for teeth don’t just create acids while they are being eaten. The acids stick around for the next half-hour.

Depending on your eating and drinking patterns, it’s possible for the bacteria to produce acid almost constantly. This can happen if you sip soft drinks or sweetened coffee throughout the day. Eating many small sweet or starchy snacks can produce the same effect. The resulting acid damage adds up, so decay is more likely. Studies have shown that people who eat sweets as snacks between meals have higher rates of decay than people who eat the same amount of sweets with their meals.

On the brighter side, some foods actually help to protect teeth from decay. That’s because they increase saliva flow and neutralize the acids produced by bacteria. This makes it less likely that the enamel will lose minerals. For example, aged cheese eaten immediately after other food helps to buffer the acid.

Chewing sugarless gums also can help protect your teeth against cavities. Xylitol is an ingredient in some sugarless gums. This sweetener has been shown to reduce the amount of bacteria in the mouth. It also helps to buffer the teeth against the effect of acid. Most sugarless gums and sugarless candies increase the flow of saliva, which helps to protect your teeth against bacteria.

Long-Term Effects:-
Like the rest of your body, your mouth depends on overall good nutrition to stay healthy. In fact, your mouth is highly sensitive to poor nutrition. It can lead to tooth loss, serious periodontal (gum) disease and bad breath.

What To Eat:-
The current and best advice for overall good nutrition is found in the Dietary Guidelines for Americans. This document was developed by the U.S. Department of Agriculture (USDA) and the Department of Health and Human Services.

The guidelines are simple in concept:

*Eat whole grains daily instead of refined grains. Whole grains include brown rice, oatmeal and whole wheat bread. Refined grains include white bread and white rice.
*Eat healthier vegetables, including dark green and orange vegetables.
*Eat a variety of fruits.
*Choose a diet with plenty of grain products, fruits and vegetables.
*Choose fish, beans, nuts and seeds for some of your protein needs.
*Choose beverages and foods to moderate your intake of sugars.
*Choose and prepare foods with less salt.
*If you drink alcoholic beverages, do so in moderation.
*Aim for a healthy weight and be physically active each day.

To help people understand these guidelines, the USDA has replaced the old Food Guide Pyramid. The new guide is an interactive tool called MyPyramid. It is actually many different pyramids, depending on a person’s age, gender and physical activity. The tool can be found at www.mypyramid.gov.

Your diet, like the pyramid, should have:

*A strong base of grains
*At least 2½ cups of vegetables a day
*At least 2 cups of fruits a day
*At least 3 cups of calcium-containing milk, yogurt and cheese
*Proteins such as meats, beans, eggs and nuts

Eat fats and sweets sparingly.

To prevent tooth decay, you should follow a few additional guidelines. This can help to keep the amount of acid created by the bacteria on your teeth to a minimum. Here are some tips:

1.Limit between-meal snacking. Fewer snacks mean less acid exposure for your teeth. If you snack, choose foods that are not fermentable carbohydrates.

*Best choices — Cheese, chicken or other meats, or nuts. These foods actually may help protect tooth enamel. They do this by neutralizing acids or by providing the calcium and phosphorus needed to put minerals back in the teeth.

*Moderate choices — Firm fruits such as apples and pears and vegetables. Firm fruits contain natural sugars. However, their high water content dilutes the effects of the sugars. These fruits also stimulate the flow of saliva, which fights bacteria and helps protect against decay. Vegetables do not contain enough carbohydrates to be dangerous.

*Worst choices — Candy, cookies, cakes, crackers, breads, muffins, potato chips, french fries, pretzels, bananas, raisins and other dried fruits. These foods provide a source of sugar that certain bacteria can use to produce acid. The problem can be worse if the foods stick to teeth or get caught between them.

2.Limit the amount of soft drinks or any other drinks that contain sugar. These include coffee or tea with added sugar, cocoa and lemonade. Fruit juices contain natural sugars that also can cause decay. Limit the amount of time you take to drink any of these drinks. Avoid sipping them throughout the day. A can of soda that you finish with a meal exposes your teeth to acids for a shorter time than a soda that takes you two hours to drink.

*Better choices —
Unsweetened tea and water, especially little fluoridated water(  as permissible by WHO). Tea also has fluoride, which can strengthen tooth enamel. Water helps flush away bits of food. It also can dilute the sugar acids.

3.Avoid sucking on hard candies or mints, even the tiny ones. They have enough sugar to increase the acid produced by bacteria to decay levels. If you need a mint, use the sugarless varieties.

4.Very acidic foods (such as citrus fruits) can make the mouth more acidic. This may contribute to a loss of minerals in the teeth. The effects of acid exposure add up over time. Every little bit counts.

5.Brush your teeth after eating and after drinking sugary drinks, to remove the plaque bacteria that create the destructive acids. If you cannot brush after every meal, brush at least twice a day.

6.Chew sugarless gum that contains xylitol. This can help reduce the risk of cavities. The gum helps dislodge some of the food stuck to your teeth. It also increases saliva flow to help neutralize the acids.

Bruxism

Alternate terms: Bite stress; Clenching; Tooth grinding.

Definition:
Bruxism (from the Greek  (brugmós), “gnashing of teeth“) is characterized by the grinding of the teeth and is typically accompanied by the clenching of the jaw. Bruxism can be defined as the grinding of teeth for non-functional purposes. Some authors refer to nocturnal grinding as bruxism while the term bruxomania is given for grinding during the day time. It is an oral parafunctional activity that occurs in most humans at some time in their lives. In most people, bruxism is mild enough not to be a health problem.  While bruxism may be a diurnal or nocturnal activity, it is bruxism during sleep that causes the majority of health issues and can even occur during short naps. Bruxism is one of the most common sleep disorders.

CLICK & SEE
Bruxism led to the loss of nearly 50% of this patient’s visible tooth structure.

Bruxism is a chronic habit of clenching or grinding the teeth. Its significance lies in the potential damage the habit can cause to all three elements of the body’s “stomatognathic system” (i.e. the teeth, jaw muscles, and jaw joints).

If you find yourself waking up with sore jaw muscles or a headache, you may be suffering from bruxism — the grinding and clenching of teeth. Bruxism can cause teeth to become painful or loose, and sometimes parts of the teeth are literally ground away. Eventually, bruxism can destroy the surrounding bone and gum tissue. It can also lead to problems involving the jaw joint, such as temporomandibular joint syndrome.
Signs:
BruxismFor many people, bruxism is an unconscious habit. They may not even realize they’re doing it until someone comments that they make a horrible grinding sound while sleeping. For others, a routine dental checkup is when they discover their teeth are worn or their tooth enamel is fractured.

Other potential signs of bruxism include aching in the face, head and neck. Your dentist can make an accurate diagnosis and determine if the source of facial pain is a result from bruxism.

Most bruxers are not aware of their bruxism, and only 5% go on to develop symptoms, such as jaw pain and headaches, which will require treatment.[6] In many cases, a sleeping partner or parent will notice the bruxism before the person experiencing the problem becomes aware of it.

Bruxism can result in abnormal wear patterns of the occlusal surface, abfractions and fractures in the teeth. This type of damage is categorised as a sign of occlusal trauma.

Over time, dental damage will usually occur. Bruxism is the leading cause of occlusal trauma and a significant cause of tooth loss and gum recession.
CLICK & SEE

The effects of bruxism on an anterior tooth, revealing the dentin and pulp which are normally hidden by enamel
In a typical case, the canines and incisors of the opposing arches are moved against each other laterally, i.e., with a side-to-side action, by the medial pterygoid muscles that lie medial to the temporomandibular joints bilaterally. This movement abrades tooth structure and can lead to the wearing down of the incisal edges of the teeth. People with bruxism may also grind their posterior teeth, which will wear down the cusps of the occlusal surface. Bruxism can be loud enough to wake a sleeping partner. Some individuals will clench the jaw without significant lateral movements. Teeth hollowed by previous decay (caries), or dental drilling, may collapse, as the cyclic pressure exerted by bruxism is extremely taxing on the tooth structure.

Symptoms :
Patients may present with a variety of symptoms, including:

1.Anxiety, stress, and tension
2.Depression
3.Earache
4.Eating disorders
5.Headache
6.Insomnia
7.Sore or painful jaw

Sequelae

Eventually, bruxism shortens and blunts the teeth being ground and may lead to myofascial muscle pain, temporomandibular joint dysfunction and headaches. In severe, chronic cases, it can lead to arthritis of the temporomandibular joints. The jaw clenching that often accompanies bruxism can be an unconscious neuromuscular daytime activity, which should be treated as well, usually through physical therapy (recognition and stress response reduction).

Causes:
Multiple articles have incorrectly cited bruxism as a reflex chewing activity; bruxism is more accurately classified as a habit. Reflex activities happen reliably in response to a stimulus, without involvement of subconscious brain activity, and bruxism does not. All habitual activities are triggered by one kind of stimulus or another, and that does not make the habit a reflex. Chewing is a complex neuromuscular activity that is controlled by subconscious processes, with higher control by the brain. During sleep, the subconscious processes become active, while the higher control is inactive, resulting in bruxism. Some bruxism activity is rhythmic (like chewing), and some is sustained (clenching). Researchers classify bruxism as “a habitual behavior, and a sleep disorder.”

The etiology of problematic bruxism is unknown, though several conditions are known to be linked to bruxism. It is theorized that certain medical conditions can trigger bruxism, including digestive ailments and anxiety.
Other Causes of Tooth Wear
Bruxing isn’t the only cause of tooth wear. Here are a couple other common sources:

?Teeth that don’t mesh properly can wear at an accelerated rate, even under normal function. If you have this problem (known as “malocclusion” in dental terms), ask your dentist if orthodontic treatment might be an option.

?Factitious habits: Repeatedly chewing on hard or abrasive objects, biting your nails, grinding sunflower seed husks and other habits like these can accelerate the formation of wear facets (flattened planes) and chips on your teeth. An occlusal guard won’t help with this, but you may need the chipped or worn teeth repaired with bonding, fillings, or crowns. And you should try to quit the habit to avoid re-occurrence.

Diagnoses:
Bruxism can sometimes be difficult to diagnose by visual evidence alone, as it is not the only cause of tooth wear. Over-vigorous brushing, abrasives in toothpaste, acidic soft drinks and abrasive foods can also be contributing factors, although each causes characteristic wear patterns that a trained professional can identify. Additionally, the presenting symptoms may be difficult for a physician to attribute to bruxism.

The effects of bruxism may be quite advanced before sufferers are aware they brux. Abraded teeth are usually brought to the patient’s attention during a routine dental examination. If enough enamel has been abraded, the softer dentin will be exposed, and abrasion will accelerate. This opens the possibility of dental decay and tooth fracture, and in some people, gum recession. Early intervention by a dentist is advisable.

The most reliable way to diagnose bruxism is through EMG (electromyographic) measurements. These measurements pick up electrical signals from the chewing muscles (masseter and temporalis). This is the method used in sleep labs. There are three forms of EMG measurement available to consumers for use outside sleep labs. The first is bedside EMG units similar to those used by sleep labs. These units can be purchased for about $2000 and pick up their signals from facial muscles through wires connecting the bedside unit to electrodes that are adhesively attached to the user’s face. TENS electrodes or ECG electrodes may be used.

The second type of EMG measurement available to consumers is a self-contained EMG measurement headband sold under the trade name SleepGuard, available on loan from some dentists or at a rental rate of $50 per month from the manufacturer. The EMG measurement headband does not require adhesive electrodes or wires attached to the face. While it does not record the exact time, duration, and strength of each clenching incident as the most expensive bedside EMG monitors do, it does record the total number of clenching incidents and the total clenching time each night. These two numbers easily distinguish clenching from rhythmic grinding and allow dentists to quantify severity levels accurately.

Bedside EMG units and the self-contained EMG measurement headband can both be used either in silent mode as a diagnosis measurement or in biofeedback mode as a treatment.

A third method of diagnosis using EMG is available in disposable form under the trade name BiteStrip. The BiteStrip is a self-contained EMG module that adhesively mounts to the side of the face over the masseter muscle. The BiteStrip can only do one night of measurement and does not display the clench count or total clenching time, but rather provides a single-digit display related to bruxism severity. The BiteStrip provides significantly less information than an EMG bedside unit or EMG headband and costs about $60 per day to use.

Associated factors:
The following factors are associated with bruxism:

*Malocclusion, in which the upper and lower teeth occlude in a disharmonic way, e.g., through premature contact of back teeth
*Relatively high levels of consumption of caffeinated drinks and foods, such as coffee, colas, and chocolate
*High levels of blood alcohol
*Smoking
*High levels of anxiety, stress, work-related stress, irregular work shifts, stressful profession and ineffective coping strategies
*Drug use, such as SSRIs and stimulants, including methylenedioxymethamphetamine (ecstasy), methylenedioxyamphetamine (MDA), methylphenidate and other amphetamines, *including those taken for medical reasons .
*Hypersensitivity of the dopamine receptors in the brain
*GHB and similar GABA-inducing analogues such as Phenibut, when taken with high frequency
*Disorders such as Huntington’s and Parkinson’s diseases.
*Obsessive Compulsive Disorder

Treatment:

Many cases of bruxism are associated with emotional and psychological disturbances. Thus appropriate psychological counseling by a psychiatrist may be initiated. Hypnosis, relaxing exercise and massage can help in relieving muscle tension. Occlusal adjustments have to carried out to eliminate prematurities. Night guards or other occlusal splints that cover the occlusal surfaces of teeth help in eliminating occlusal interference, prevent occlusal wear and break the neuromuscular adaptation.

Self-care steps:

*Relax your facial and jaw muscles throughout the day. The goal is to make facial relaxation a habit.
*Massage the muscles of the neck, shoulders, and face.
*Learn physical therapy stretching exercises to help the restore a normal balance to the action of the muscles and joint on each side of the head.
*Apply ice or wet heat to sore jaw muscles
*Avoid eating hard foods like nuts, candies, steak.
*Drink plenty of water every day.
*Try to reduce your daily stress and learn relaxation techniques.
*Get plenty of sleep.

There is no single accepted cure for bruxism.  However, treatments are available.

Bruxism may be reduced or even eliminated when the associated factors, e.g., sleep disorders, are treated successfully.

Mouthguards and splints
Ongoing management of bruxism is based on minimizing the abrasion of tooth surfaces by the wearing of an acrylic dental guard, or splint, designed to the shape of an individual’s upper or lower teeth from a bite mold. Mouthguards are obtained through visits to a dentist for measuring, fitting, and ongoing supervision. There are four possible goals of this treatment: constraint of the bruxing pattern such that serious damage to the temporomandibular joints is prevented, stabilization of the occlusion by minimizing the gradual changes to the positions of the teeth that typically occur with bruxism, prevention of tooth damage, and the enabling of a bruxism practitioner to judge—in broad terms—the extent and patterns of bruxism through examination of the physical indentations on the surface of the splint. A dental guard is typically worn on a long-term basis during every night’s sleep. Although mouthguards are a first response to bruxism, they do not in fact help cure it. These mouthguards can cost anywhere from $200 to $650. Professional treatment is medically recommended to ensure proper fit, make ongoing adjustments as needed.

Another type of device sometimes given to a bruxer is a repositioning splint. A repositioning splint may look similar to a traditional night guard, but is designed to change the occlusion, or bite, of the patient. Randomly controlled trials with these type devices generally show no benefit[17][18] over more conservative therapies.

Nociceptive trigeminal inhibitor
The NTI-tss device is another option that can be considered. Nociceptors are nerves that sense and respond to pressure. The trigeminal nerve supplies the face and mouth. The NTI appliance fits on top of the teeth and alters the angle at which the jaw opens, by covering only the front teeth and preventing the rear molars from coming into contact, thus limiting the contraction of the temporalis muscle. When the grinding starts in the night the pressure which is applied to the two front teeth can, it is claimed, send quite a strong alarm signal to the brain. The NTI device must be fitted by a dentist.

The efficacy of such devices is debated. Some writers propose that irreversible complications can result from the long-term use of mouthguards and repositioning splints.

Biofeedback
Various biofeedback devices are currently available, and effectiveness varies significantly depending on whether the biofeedback is used only during waking hours, or during sleep as well. Many authorities remain unconvinced of the efficacy of daytime-only biofeedback.[21] The efficacy of biofeedback delivered during sleep can depend strongly on daytime training, which is used to establish a Pavlovian response to the biofeedback signal that persists during sleep.

The first wearable nighttime bruxism biofeedback device (introduced in 2001), was originally sold under the trademark GrindAlert by BruxCare, and is now sold under the trademark SleepGuard by Holistic Technologies, which owns the patents on the technology. The SleepGuard biofeedback headband is a battery-powered device that sounds a tone against the forehead when it senses EMG (electromyographic) muscle activity in the temporalis muscles. The tone starts out very quiet and then gets louder, allowing people to stop clenching without waking up. This device records and displays nightly data on the number of bruxism events that last for at least two seconds and the total accumulated duration of those events. The volume of the alarm and the bite force required to trigger the device are adjustable. After proper Pavlovian training during waking hours, more than 50% of users achieve significantly reduced bruxism.[22] The biofeedback sound on the headband is designed to come on slowly, allowing users to subconsciously respond in their sleep without waking up. The manufacturer offers a free three-week trial so that only people who find the device works well for them have to pay for it and claims that less than 15% of trial units are returned.

A mild electric shock bio-feedback device for treating Bruxism, GrindCare,[23] has been approved by the European regulatory authorities and was introduced to the market in 2Q2008 – and was approved by FDA Authorities in the US in early 2010. The device works by using simple electrodes mounted on the skin close to the cheek bones prior to sleeping; it detects the initial muscular contractions and immediately provides mild electrical shock pulses to the facial muscles. The electric shocks serve to interrupt bruxism activity. The device is worn on the head and reportedly reduces grinding, usually without interfering with the sleep of the patient as described by Jadidi, Castrillon & Svensson.   Thereby facial tension, joint defects and teeth disruption are reportedly reduced.

A taste-based biofeedback method was developed by Moti Nissani, Ph.D. and is called “The Taste-Based Approach to the Prevention of Teeth Clenching and Grinding”.     The therapy involves suspending sealed packets containing a bad-tasting substance (e.g. hot sauce, vinegar, denatonium benzoate, etc.) between the rear molars using an orthodontic-style appliance. Any attempt to bring the teeth together will rupture the packets and alert the user to the habit. This approach finds favor with some people who prefer to relate to biofeedback as “aversive therapy”. The Taste-Based Approach claims to suffer less from desensitization over time than sound-based biofeedback approaches may have, but may interrupt sleep more. (There is effectively no limit to the aversive taste of certain substances. We[who?] can therefore be sure that some harmless substance exists that will alert anyone to the habit.)

One bruxism biofeedback device which was briefly on the market but is no longer available was sold under the trademark Oralsensor. This device consisted of a pneumatic pouch embedded in a soft polymer plate that fits over upper or lower teeth. When the teeth came together with a force that exceeded a set threshold, an alarm is sounded in an earpiece worn by the user; the device is no longer sold.

In 2005, a new type of occlusive device was patented that produces a movement incompatible with teeth clenching. When nighttime bruxism occurs, people breathe through the nose. The device forces people to breathe through the mouth; by forcing the opening of the mouth, the device is claimed to stop clenching. The occlusive device has an electromyogram system that monitors the electric activity of the jaw muscle via wireless electrodes. These electrodes transfer jaw-muscle activity by radio frequency to an external monitoring system. Once the signal has been interpreted by the monitoring system, if a person clenches, the monitoring unit sends a radio frequency signal to a transceiver integrated in a mechanical actuator. The mechanical actuator has two occlusive flaps that block the nostrils, forcing breathing to occur through the mouth. Once the patient stops clenching, the flaps open, allowing breathing through the nose again. The occlusive device does not wake up people since it blocks nostrils slowly, and it never closes them completely to avoid sleep disruption.

Botox
Botulinum toxin (Botox) can be successful in lessening effects of bruxism, though serious side-effects are possible. Less than one microgram ingested or inhaled is sufficient to kill an adult human. In extremely dilute form (Botox), this toxin is used as an injectable medication that weakens (partially paralyzes) muscles and has been used extensively in cosmetic procedures to relax the muscles of the face and decrease the appearance of wrinkles. In April, 2008, a study was published in the Journal of Neuroscience  that showed that facially injected Botox can and does propagate into the brains of some test animals, and the U.S. Food and Drug Administration (FDA) announced that it was beginning a safety review of Botox and other similar drugs.

Botox was not originally developed for cosmetic use. It was, and continues to be, used to treat diseases of muscle spasticity such as blepharospasm (eyelid spasm), strabismus (crossed eyes) and torticollis (wry neck). Bruxism can also be regarded as a disorder of repetitive, unconscious contraction of the masseter muscle (the large muscle that moves the jaw). In the treatment of bruxism, Botox works to weaken the muscle enough to reduce the effects of grinding and clenching, but not so much as to prevent proper use of the muscle. The strength of Botox is that the medication goes into the muscle and is not supposed to get absorbed into the body (though the new research shows it does). The procedure involves about five or six simple, relatively painless injections into the masseter muscle. It takes a few minutes per side, and the patient starts feeling the effects the next day. Occasionally, some bruising can occur, but this is quite rare. Injections must be repeated more than once per year, and the risk factor of spread of the botulinum toxin is compounded by this repetition.

The symptoms that can be helped by this procedure include:

*Grinding and clenching
*Morning jaw soreness
*TMJ pain
*Muscle tension throughout the day
*Migraines triggered by clenching
*Neck pain and stiffness triggered by clenching

The optimal dose of Botox must be determined for each person as some people have stronger muscles that need more Botox. This is done over a few touch-up visits with the physician injector. This treatment is expensive, but sometimes Botox treatment of bruxism can be billed to medical insurance. The effects last for about three months. The muscles do atrophy, however, so after a few rounds of treatment, it is usually possible either to decrease the dose or increase the interval between treatments.

Other authorities caution that Botox should only be used for temporary relief for severe cases and should be followed by diagnosis and treatment to prevent future bruxism or jaw clenching, suggesting that prolonged use of Botox can lead to permanent damage to the jaw muscle.

Dietary supplements
There is anecdotal evidence that suggests taking certain combinations of dietary supplements may alleviate bruxism; pantothenic acid[citation needed], magnesium,   and calcium   are mentioned on dietary supplement websites. Calcium is known to be a treatment for gastric problems, and gastric problems such as acid reflux are known to increase bruxism .

Repairing damage
Damaged teeth can be repaired by replacing the worn natural crown of the tooth with prosthetic crowns. Materials used to make crowns vary; some are less prone to breaking than others and can last longer. Porcelain fused to metal crowns may be used in the anterior (front) of the mouth; in the posterior, full gold crowns are preferred. All-porcelain crowns are now becoming more and more common and work well for both anterior and posterior restorations. To protect the new crowns and dental implants, an occlusal guard should be fabricated to wear during sleep.

White Wines ‘Bad for the Teeth’

Teeth of a model.

[amazon_link asins=’B00FYOB0S8,B00004OCKO,B0155VPARQ,B00SBYP174′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’0a1e5666-5c87-11e7-930b-354dfccd4da7′]Enjoying a glass of white wine on a frequent basis can damage the teeth, something many wine makers and tasters will know first-hand, experts say.
……………....CLICK & SEE
Pale plonk packs an acidic punch that erodes enamel far more than red wine, Nutrition Research reports.

It is not the wine’s vintage, origin or alcohol that are key but its pH and duration of contact with the teeth.

Eating cheese at the same time could counter the effects, because it is rich in calcium, the German authors say.

It is the calcium in teeth that the wine attacks.

In the lab, adult teeth soaked in white wine for a day had a loss of both calcium and another mineral called phosphorus to depths of up to 60 micrometers in the enamel surface, which the researchers say is significant.

Riesling wines tended to have the greatest impact, having the lowest pH.

A “kinder” tooth choice would be a rich red like a Rioja or a Pinot noir, the Johannes Gutenberg University team found.

Power of saliva
Even if people brush their teeth after a night of drinking, over the years repeated exposure could take its toll, say Brita Willershausen and her colleagues.

Indeed, excessive brushing might make matters worse and lead to further loss of enamel.

But they said: “The tradition of enjoying different cheeses for dessert, or in combination with drinking wine, might have a beneficial effect on preventing dental erosion since cheeses contain calcium in a high concentration.”

This helps neutralise and boost the remineralising power of saliva to halt the acid attack.

But eating strawberries while supping on your vino or mixing sparkling whites with acid fruit juice to make a bucks fizz may spell trouble because this only adds to the acid attack.

Professor Damien Walmsley, of the British Dental Association, said: “The ability of acidic foods and drinks to erode tooth enamel is well understood, and white wine is recognised as being more erosive than red.

“But it’s the way you consume it that’s all important. If you’re going to have a glass of wine do so with your meal and leave a break of at least 30 minutes afterwards before you brush your teeth and go to bed.

“Consuming wine alongside food, rather than on its own, means the saliva you produce as you chew helps to neutralise its acidity and limits its erosive potential.

“If you’re going to have a glass of wine do so with your meal and leave a break of at least 30 minutes afterwards before you brush your teeth and go to bed.”….Says Professor Damien Walmsley of the British Dental Association

“And leaving time before brushing teeth gives the enamel a chance to recover from the acid attack and makes it less susceptible to being brushed away.”

Orange Juice May Damage Teeth Enamel

Some juice is so acidic, it can take part of your teeth with it.

New warning: A U.S. expert says orange juice is so strong it can ‘literally wash away your teeth’

Fruit beverages can cut enamel hardness by 84 per cent causing teeth to erode more than previously thought, according to one U.S. expert.

Dr Yan-Fang Ren, of the Eastman Institute for Oral Health, at the University of Rochester Medical Centre in New York, said the acid in orange juice ‘is so strong that the tooth is literally washed away’.

Dr Ren and his team made the discovery after studying the effects of over-the-counter teeth whitening products.

He found the effect of six per cent hydrogen peroxide, the common ingredient used for teeth whitening, was ‘insignificant’ compared with acidic fruit juices.

The orange juice markedly cut hardness and increased roughness of tooth enamel.

The researchers used a revolutionary vertical scanning microscope for the first time to see the extensive surface detail on teeth.

It has long been known that fruit juice and carbonated drinks have high acid content and can reduce the strength of enamel.

Dentists have advised some of these drinks should only be consumed with a straw or at the same time as eating food.

But the damaging effects of drinks could be worse than previously thought, according to the article in the Journal of Dentistry.

Weakened and eroded enamel may speed up the wear of the tooth and increase the risk of tooth decay developing and spreading.

Dr Ren said: ‘Most soft drinks, including sodas and fruit juices, are acidic in nature.

‘Our studies demonstrated that the orange juice, as an example, can potentially cause significant erosion of teeth. It’s potentially a very serisevereous problem for people who drink sodas and fruit juices daily.

‘We do not yet have an effective tool to avert the erosive effects, although there are early indications that higher levels of fluoride may help slow down the erosion.’

Dr Ren advises consumers to be aware of the acidic nature of beverages, including sodas, fruit juices, sports and energy drinks.

The longer teeth are in contact with the acidic drinks, the more the erosion will be.

Those who sip their drinks slowly over 20 minutes are more likely to have tooth erosion than those who finish a drink quickly.

Dr Ren said it is important to keep good oral hygiene by brushing teeth twice a day with fluoride toothpaste.

The research comes after a recent study revealed that drinking fruit juice dramatically reduces the effectiveness of drugs used to treat cancer, heart conditions and high blood pressure.

Research has shown that orange, apple and grapefruit juice can also wipe out the benefits of some antibiotics and hay-fever pills.

It is thought the drinks stop drugs from entering the bloodstream and getting to work in the body – possibly rendering them useless.

The potential effects are so serious, researchers warned, that if in doubt patients should swap fruit juices for water when on medication.
