Secrets Your Dentist Doesn’t Want You To Know

Here are the secrets your dentist may not want you to know — but you need to know to get the best care possible:

………………..
Secret #1: Your dentist may not be as educated as you think.

Dentistry has changed a lot since your dentist graduated from dental school. There have been major advances in most materials used in fillings, bonding and root canals. If your dentist is not actively engaged in continuing education, it is unlikely that he or she is keeping up with these developments.

Secret#2. Your dentist may not have the latest technology. ret #2:

Digital x-ray: Dentists who do not have digital x-ray equipment are practicing in the dark ages. Digital x-rays use less radiation than film. They are easier to read and the ability to manipulate contrast makes diagnosis more accurate.

Ultrasonic Cleaning: Ultrasonic instruments vibrate plaque and calculus off your teeth, even in areas below your gums. It is much more comfortable than old-fashioned hand scraping.

CEREC: The CEREC system lets your dentist provide a ceramic crown or veneer in only one visit. CEREC means fewer injections, less drilling and no annoying temporaries.

Diagnodent: This is a laser that the dentist shines on the tooth and it tells whether there is a cavity and how deep it is. With the use of this technology, the dentist can detect cavities, and find them at an earlier stage, than traditional poking around the tooth.

Secret #3: Your dentist may be using mercury.

Mercury is toxic. Norway and Sweden have banned the use of mercury fillings.. But mercury fillings are less expensive and easier for the dentist to use. If your dentist does not use composite fillings, don’t go to that dentist any more. In the US, the FDA is way behind the ball and not actively warning patients about this like they have been mandated by the courts to do.

Secret #4: The lab may be more important than your dentist.

Dental labs create dentures, crowns, bridges, orthodontic appliances, and other dental restorations like implant crowns. There is a huge difference in the quality of these labs. You should be particularly wary if your dentist is using a lab in China or Mexico. Some of the top labs in the U.S. are Aurum Ceramics, MicroDental Laboratories, da Vinci Dental Studio, and Williams Dental Lab.

Secret #5: There’s more to good dentistry than filling cavities.

A competent dentist screens for more than tooth decay. He or she should be concerned about sleep apnea, jaw-related pain known as TMJ or temporomandibular joint disorder, periodontal disease, oral cancer, diabetes and hypertension.

Secret #6: You are probably using the wrong specialist for dental implants.

Since dental implants involve the removal of a tooth and replacing it with an artificial tooth, many patients assume that an oral surgeon is best qualified to do it. This can be a flawed assumption. Periodontists, who specialize in gum disease, may be a better option. Periodontists have special training in gum tissue and underlying bone in the mouth, which are significant issues in dental implants.

Secret #7: Bad dental advice about dentures can be fatal!

Dentures are no joke. Your dentist should examine your dentures for evidence of wear. Wearing down the teeth on your dentures can result in distorted facial characteristics, collapse of the bite and closure of the airway.

Secret #8: Your dentist may not know enough about sleep apnea.

The most common form of sleep apnea is caused by a blockage of the airway during sleep. It is a pretty scary condition. The patient can stop breathing hundreds of times during the night. A common treatment for sleep apnea is Continuous Positive Airway Pressure (CPAP), which involves blowing pressurized room air through the airway at high enough pressure to keep the airway open.

As an alternative, your dentist, working with your physician, can custom make a device that guides the lower jaw forward, called a mandibular advancement device or MAD. MAD devices are more comfortable to wear and the compliance rates are much higher than using CPAP.

Secret #9: Not all cosmetic dentists have the skills to really improve your smile.

Any dentist can call herself a “cosmetic dentist.” Your dentist should be able to show you ten or more before and after photographs or videos, and be willing to give you the names of patients who have consented to be used as references.

Secret #10: How to avoid the root canal your dentist says you need.

Ask about the “ferrule effect.” Technically, this means that a root canal is unlikely to be successful if there is not enough tooth structure above the gum line to protect the tooth from coming loose or fracturing after it has been prepared for a crown. If your tooth fails the “ferrule effect” test, you might be better off with an extraction and an implant.

Be VERY Careful When Replacing Missing Teeth

 

By Dr. Lina Garcia

A dental implant is one option for replacing missing or badly diseased teeth. It is composed of an artificial root that looks like a post or screw and is covered with a dental crown.
……………....CLICK & SEE
Treatment involves the surgical placement of the implant into the jawbone, where it is allowed to fuse to the bone in a process called “osseointegration.”

Once healed, the implant acts as an anchor for an artificial replacement tooth, or crown. The crown is made to blend in with your other teeth and is permanently attached to the implant.

A typical dental implant is made of pure titanium and/or a titanium alloy.

In fact, titanium alloys are widely used in both medicine and dentistry, for dental implants, pacemakers, stents, orthodontal brackets, and orthopedic implants (e.g., hip, shoulder, knee, or elbow). Not only is titanium strong, but many consider it biocompatible: it forms an oxide layer when exposed to air, and this purportedly results in reduced corrosion and superior osseointegration.

So why should you reject the standard titanium metal implant?

Titanium is NOT Biologically Inert

Titanium implants release metal ions into your mouth 24 hours a day, and this chronic exposure may trigger inflammation, allergies, and autoimmune disease in susceptible individuals. They are a precursor to disease.

Cases of intolerance to metal implants have been reported over the years, and the removal of this incompatible dental material has resulted in reduced metal sensitivity and long-term health improvement in the majority of patients.

Titanium has the potential to induce hypersensitivity as well as other immunological dysfunctions.

One study investigated 56 patients who developed severe health problems after receiving titanium-based dental implants. These medical problems included muscle, joint, and nerve pain; chronic fatigue syndrome; neurological problems; depression; and skin inflammation.

Removal of the implants resulted in a dramatic improvement in the patients’ symptoms, as well as a decrease in many patients’ sensitivity to titanium.

For example, a 54-year-old man with a titanium dental implant and four titanium screws in his vertebra was so sick that he could not work. He suffered from chronic fatigue syndrome, cognitive impairment, Parkinson-like trembling, and severe depression. Six months after the removal of the implants and screws, he was able to return to work.

In another case, a 14-year-old girl developed inflammatory lesions on her face six months after being fitted with titanium orthodontal brackets.

She was also mentally and physically exhausted, and her reactivity to titanium skyrocketed. Within nine months of replacing the brackets with a metal-free material, her facial lesions had almost completely healed, she was healthy and active, and her sensitivity to titanium returned to a normal level.

Titanium Implants Can Cause Cancer

Another complication of the use of implanted titanium is its potential to induce the abnormal proliferation of cells (neoplasia), which can lead to the development of malignant tumors and cancer. Through rare, it is a well-known complication of orthopedic surgery that involves the implantation of metallic hardware.

Furthermore, researchers recently uncovered the first reported case of a sarcoma arising in association with a dental implant.

As described in the August 2008 issue of JADA (The Journal of the American Dental Association), a 38-year-old woman developed bone cancer eleven months after receiving a titanium dental implant. Luckily, she was successfully treated with chemotherapy, but the authors recommended further research into the tumor-causing potential of dental implants in light of their increasing popularity and their ability to last for longer periods of time.

Why You Want to Avoid ANY Kind of Metal in Your Mouth

Finally, the presence of any metal in your mouth sets the stage for “galvanic toxicity,” because your mouth essentially becomes a charged battery when dissimilar metals sit in a bed of saliva.
All that is needed to make a battery is two or more different metals and a liquid medium that can conduct electricity (i.e., an electrolyte). Metal implants, fillings, crowns, partials, and orthodontics provide the dissimilar metals, and the saliva in your mouth serves as the electrolyte.

An electric current called a galvanic current is then generated by the transport of the metal ions from the metal-based dental restorations into the saliva. This phenomenon is called “oral galvanism,” and it literally means that your mouth is acting like a small car battery or a miniature electrical generator. The currents can actually be measured using an ammeter!

Oral galvanism creates two major concerns.

First, the electric currents increase the rate of corrosion (or dissolution) of metal-based dental restorations. Even precious metal alloys continuously release metal ions into your mouth due to corrosion, a process that gnaws away bits of metal from the metal’s surface.

These ions react with other components of your body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease. Increasing the corrosion rate, therefore, increases the chance of developing immunologic or toxic reactions to the metals.

Second, some individuals are very susceptible to these internal electrical currents. Dissimilar metals in your mouth can cause unexplained pain, nerve shocks, ulcerations, and inflammation, and many people also experience a constant metallic or salty taste, or a burning sensation in their mouth.

Moreover, there is the concern that oral galvanism directs electrical currents into brain tissue and can disrupt the natural electrical current in your brain.

New Alternatives to Titanium Implants

In recent years, high-strength ceramic implants have become attractive alternatives to titanium implants, and some current research has focused on the viability of materials such as zirconia (the dioxide of zirconium, a metal close to titanium on the periodic table).
………………
Metal-free zirconia implants have been used in Europe and South America for years, but they have only recently become available in the U.S.

Zirconia implants are highly biocompatible to the human body and exhibit minimum ion release compared to metallic implants.

Studies have shown that the osseointegration of zirconia and titanium implants are very similar, and that zirconia implants have a comparable survival rate, thereby making them an excellent alternative to metal implants.

Moreover, zirconia ceramics have been successfully used in orthopedic surgery to manufacture ball heads for total hip replacements.

Therefore, given that titanium dental implants can induce metal sensitivity, inflammation, autoimmunity, and malignant tumors, while zirconia implants are metal-free but just as durable, why invite chronic metal exposure?

Your body would surely benefit from choosing the biocompatible, ceramic dental implant over the standard, titanium metal implant.

Dr. Lina Garcia, a committed holistic dentist for 25 years, has dedicated her practice to using dental materials that will support your health and not disease. In her practice, she offers only metal-free restorative materials, including zirconia implants.

Crowded Teeth

What is Crowded or Crooked teeth?
Crowded or crooked teeth that overlap, protrude, or recess in a haphazard fashion can often be perceived as a personal disfigurement. If you feel embarassed to smile, then you should consider having your teeth straightened out.
………….CLICK & SEE
Apart from looking aesthetically unpleasing, crowded teeth also affect the general dental condition of your mouth. They tend to attract food deposits, which get trapped in the narrow spaces, and are difficult to keep clean with routine oral hygiene. This leads to higher incidence of tooth decay and gum disease.

What causes orthodontic problems ?

Most orthodontic problems like crowding,spacing,protrusion,extra or missing teeth and jaw growth problemshave a genetic origin.

Why is treatment important ?
Crooked,crowded and irregular teeth are hard to clean and maintain,these problems can contribute to tooth decay,gum problems and tooth loss.A bad bite can also cause an abnormal wear of tooth surfaces,difficulty in chewing,speaking and abnorml stress on supporting bone and tissueand possible joint problems,children and adultswhose malocclusion are left untreated may go through life feeling self conciousness,hiding their smiles with tight lips or keeping a protective hand.

The objective of any corrective therapy is to create an illusion of well-aligned teeth in relation to lip position when you smile. Such an illusion can sometimes be achieved by means of cosmetic contouring, the technical term used to reshape teeth. In more involved cases, it may be necessary to use bonding to build-out a portion of a tooth to create the impression of alignment. As the cases get more complex, we may need to veneer or crown the teeth to achieve the necessary objective.
……………………
A child with severely crowded teeth. Such a case will need orthodontic treatment to achieve an acceptable result.
It may be necessary on occasion to extract certain teeth in conjunction with orthodontics, particularly in cases where crowding is extreme.

What about the problems of teenagers ?
When you think of orthodontics you tend to think of teenagers.And the fact is that orthodontic treatment in most cases begins between 9 and 14 years of age.It is important to know for the parents that some orthodontic problems are easier to correct in the early stages.

Does orthodontic treatment have any harmful effects ?

There is some discomfort or pain in the teeth after fixing the braces,which usually subsides within a week,the myth that the orthodontic treatment weakens the tooth is not correct.

Does extraction of teeth necessary for orthodontic treatment  ?
It depends on the severity of the problem,severly crowded,irregular teeth which are out of alignment cannot be aligned without the extraction of teethand no residual space is left after the treatment.

Till some years ago, orthodontic treatment was the only solution to crowded teeth. But now we have an alternative in cosmetic dentistry. We may add that orthodontics is still widely used in the younger population, while cosmetic procedures are more useful in professionals who may not have the time necessary to carry out the orthodontic procedures. Cosmetic dentistry is also useful in the older generation, who may not have an ideal gum or bone condition necessary to withstand the orthodontic forces.
Laminating with ceramic veneers can provide a pleasing result. This patient is a female adult who did not have the time to go in for orthodontic treatment. The protruding tooth was reduced to first bring it into alignment with the other teeth, and then both the front teeth were veneered.
The other two side teeth were cosmetically contoured to change their alignment, thus giving a fairly acceptable result.

Crowded teeth may require a combination of treatments in order to achieve an aesthetically and functionally satisfactory result. Individual problems require individual solutions, and the final decision about the right treatment procedure for you will be made by your dentist.

Wisdom Teeth

Wisdom teeth are third molars that usually appear between the ages of 16 and 24. They are commonly extracted when they affect other teeth—this impaction is colloquially known as “coming in sideways.”Most people have four wisdom teeth, but it is possible to have more or fewer. Absence of one or more wisdom teeth is an example of hypodontia. Any extra teeth are referred to as supernumerary teet.

CLICK & SEE

Vesitigiality and variation:
Wisdom teeth are vestigial third molars. In earlier times, when tooth loss in early adulthood was common, an additional molar had the potential to fill in a gap left by the loss of another tooth. It has also been postulated that the skulls of human ancestors had larger jaws with more teeth, which were possibly used to help chew down foliage to compensate for a lack of ability to efficiently digest the cellulose that makes up a plant cell wall. As human diet changed, a smaller jaw was selected by evolution, yet the third molars, or “wisdom teeth”, still commonly develop in human mouths.

Other findings suggest that a given culture’s diet is a larger factor than genetics in the development of jaw size during human development (and, consequently, the space available for wisdom teeth).

Impactions:

Impacted wisdom teeth fall into one of several categories. Mesioangular impaction is the most common form (43%), and means the tooth is angled forward, towards the front of the mouth. Vertical impaction (38%) occurs when the formed tooth does not erupt fully through the gum line. Distoangular impaction (6%) means the tooth is angled backward, towards the rear of the mouth. And finally, Horizontal impaction (3%) is the least common form, which occurs when the tooth is angled fully ninety degrees forward, growing into the roots of the second molar.

Typically distoangular impactions are the easiest to extract in the maxilla and most difficult to extract in the mandible, while mesioangular impactions are the most difficult to extract in the maxilla and easiest to extract in the mandible.

Impacted wisdom teeth may also be categorized on whether they are still completely encased in the jawbone. If it is completely encased in the jawbone, it is a bony impaction. If the wisdom tooth has erupted out of the jawbone but not through the gumline, it is called a soft tissue impaction.

Sometimes the wisdom tooth fails to erupt completely through the gum bed and the gum at the back of the wisdom tooth extends over the biting surface, forming a soft tissue flap or lid around the tooth called an operculum. Teeth covered by an operculum can be difficult to clean with a toothbrush. Additional cleaning techniques can include using a needle-less plastic syringe to vigorously wash the tooth with moderately pressured water or to softly wash it with hydrogen peroxide.

However, debris and bacteria can easily accumulate under an operculum, which may cause pericoronitis, a common infection problem in young adults with partial impactions that is often exacerbated by occlusion with opposing 3rd or 2nd molars. Common symptoms include a swelling and redness of the gum around the eruption site, difficulty in opening the mouth, a bad odor or taste in the mouth, and pain in the general area which may also run down the entire lower jaw or possibly the neck. Untreated pericoronitis can progress to a much more severe infection.

If the operculum does not disappear, recommended treatment is extraction of the wisdom tooth. An alternative treatment involving removal of the operculum, called operculectomy, has been advocated. There is a high risk of permanent or temporary numbness of the tongue due to damage of the nerve with this treatment and it is no longer recommended as a standard treatment in oral surgery.

Extraction:
A wisdom tooth is extracted to correct an actual problem or to prevent problems that may come up in the future. Wisdom teeth are extracted for two general reasons: either the wisdom teeth have already become impacted, or the wisdom teeth could potentially become problematic if not extracted. Potential problems caused by the presence of properly grown-in wisdom teeth include infections caused by food particles easily trapped in the jaw area behind the wisdom teeth where regular brushing and flossing is difficult and ineffective. Such infections may be frequent, and cause considerable pain and medical danger. Another reason to have a wisdom tooth removed is if the tooth has grown in improperly, causing the tongue to brush up against it. The tongue can tolerate it for a limited time, until it causes a painful sensation, to the point where the sheer pain can numb the tongue affected, and the area around it (part of the lips, and the cheek). The numbness feels similar to the feeling of anesthesia, possibly meaning a nerve can be affected by the wisdom tooth improperly growing in. Also, it is a wise choice to have them removed if undergoing extensive orthodontic work because once the teeth have come in they could inflict some damage on expensive straightening.

The extraction of wisdom teeth should only be performed by dental professionals with proper training and experience performing such extractions. The precise reasons why an individual’s wisdom teeth need to be extracted should be explained to them by their dentist, after an examination which almost certainly will need to include x-rays. A panoramic x-ray (aka “panorex”) is the best x-ray to view wisdom teeth and diagnose their problems.

Post-extraction problems
There are several problems that can manifest themselves after the extraction(s) have been completed. Some of these problems are unavoidable and natural, while others are under the control of the patient. The suggestions contained in the sections below are general guidelines that a patient will be expected to abide by, but the patient should follow all directions that are given by the surgeon in addition to the following guidelines. Above all, the patient must not disregard the given instructions; doing so is extremely dangerous and could result in any number of problems ranging in severity from being merely inconvenient (dry socket) to potentially life-threatening (serious infection of the extraction sites).

Bleeding and oozing:
Bleeding and oozing is inevitable and should be expected to last up to three days (although by day three it should be less noticeable). Rinsing out one’s mouth during this period is counter-productive, as the bleeding stops when the blood forms clots at the extraction sites, and rinsing out the mouth will most likely dislodge the clots. The end result will be a delay in healing time and a prolonged period of bleeding. However, after about 24 hours post-surgery, it is best to rinse with lukewarm saltwater to promote healing. This should be done every 2 hours until the swelling goes down and every 4-6 hours after that for at least a week. Gauze pads should be placed at the extraction sites, and then should be bitten down on with firm and even pressure. This will help to stop the bleeding, but should not be overdone as it is possible to irritate the extraction sites and prolong the bleeding. The bleeding should decrease gradually and noticeably upon changing the gauze. If the bleeding lasts for more than a day without decreasing despite having followed the surgeon’s directions, the surgeon should be contacted as soon as possible. This is not supposed to happen under normal circumstances and signals that a serious problem is present. A wet tea bag can replace the gauze pads. Tannic acid contained in tea can help reduce the bleeding.

Due to the blood clots that form in the exposed sockets as well as the abundant bacterial flora in the mouth, an offensive smell may be noticeable a short time after surgery. The persistent odour often is accompanied by an equally rancid-tasting fluid seeping from the wounds. These symptoms will diminish over an indefinite amount of time, although one to two weeks is normal. While not a cause for great concern, a post-operative appointment with your surgeon seven to ten days after surgery is highly recommended to make sure that the healing process has no complications and that the wounds are relatively clean. If infection does enter the socket, a qualified dental professional can gently plunge a plastic syringe (minus the hypodermic needle) full of a mixture of equal parts hydrogen peroxide and water or chlorohexidine gluconate into the sockets to remove any food or bacteria that may collect in the back of the mouth. This is less likely if the person has his wisdom teeth removed at an early age.

Dry socket :
A dry socket is not an infection; it is the event where the blood clot at an extraction site is dislodged, falls out prematurely, or fails to form. It is still not known how they form or why they form. In some cases, this is beyond the control of the patient. However, in other cases this happens because the patient has disregarded the instructions given by the surgeon. Smoking, spitting, or drinking with a straw in disregard to the surgeon’s instructions can cause this, along with other activities that change the pressure inside of the mouth, such as playing a musical instrument. The risk of developing a dry socket is greater in smokers, if the patient has had a previous dry socket, in the lower jaw, and following complicated extractions. The extraction site will become irritated and pain is due to the bone lining the tooth socket becoming inflamed (osteitis). The symptoms are made worse when food debris is trapped in the tooth socket. The patient should contact his/her surgeon if they suspect that they have a case of dry socket; the surgeon may elect to clean the socket under local anesthetic so another blood clot forms or prescribe medication in topical form to apply to the affected site. A non-steroidal anti-inflammatory drug such as ibuprofen may be prescribed by the surgeon for pain relief. Generally dry sockets are self limiting and heal in a couple of weeks without treatment.

Swelling:

Swelling should not be confused with dry socket, although painful swelling should be expected and is a sign that the healing process is progressing normally. There is no general duration for this problem; the severity and duration of the swelling vary from case to case. The instructions the surgeon gives the patient will tell the patient for how long they should expect swelling to last, including when to expect the swelling to peak and when the swelling will start to subside. If the swelling does not begin to subside when it is supposed to, the patient should contact his or her surgeon immediately. While the swelling will generally not disappear completely for several days after it peaks, swelling that does not begin to subside or gets worse may be an indication of infection. Swelling that re-appears after a few weeks is an indication of infection caused by a bone or tooth fragment still in the wound and should be treated immediately.

Nerve injury:
This is primarily an issue with extraction of third molars, but can occur with the extraction of any tooth should the nerve be in close proximity to the surgical site. Two nerves are typically of concern and are found in duplicate (on the left and right side):

The inferior alveolar nerve, which enters the mandible at the mandibular foramen and exits the mandible at the sides of the chin from the mental foramen. This nerve supplies sensation to the lower teeth on the right or left half of the dental arch, as well as sense of touch to the right or left half of the chin and lower lip.
The lingual nerve, which branches off the mandibular branches of the trigeminal nerve and courses just inside the jaw bone, entering the tongue and supplying sense of touch and taste to the right and left half of the anterior 2/3 of the tongue as well as the lingual gingiva (i.e. the gums on the inside surface of the dental arch).
Such injuries can occur while lifting teeth (typically the inferior alveolar) but are most commonly caused by inadvertent damage with a surgical drill. Such injuries are rare and are usually temporary. Depending on the type of injury (i.e. Seddon classification: neuropraxia, axonotmesis, and neurotmesis) they can be prolonged or permanent.

Treatment controversy:
Preventive removal of the third molars is a common practice in developed countries despite the lack of scientific data to support this practice. In 2006, the Cochrane Collaboration published a systematic review of randomized controlled trials in order to evaluate the effect of preventative removal of asymptomatic wisdom teeth. The authors found no evidence to either support or refute this practice. There was reliable evidence showing that preventative removal did not reduce or prevent late incisor crowding. The authors of the review suggested that the number of surgical procedures could be reduced by 60% or more.
