Everyday Beverages May Cause Dental Erosion

Researchers have warned people to beware of the damage that acidic beverages have on teeth. Yet, for some, the damage and problems associated with drinking sodas, citric juices, or certain teas may have already begun to take effect.
………………….BEVERAGES
In a recent study, Dr. Mohamed A. Bassiouny revealed three steps to rehabilitate teeth that suffer from dental erosion as a result of the excessive consumption of these products.

Dr. Bassiouny instructs those who are experiencing tooth erosion to first, identify the source of erosion. Then, you should determine and understand how this source affects the teeth in order to implement measures to control and prevent further damage. Lastly, you should stop or reduce consumption of the suspected food or beverage to the absolute minimum.

Information about the acid content of commonly consumed foods or beverages is usually available online or on the product’s label.

Drink Brewed Tea to Protect Your Teeth

Forget lattes and fresh lime juice, the best thing to drink is brewed tea, for it has no erosive effect on teeth and its antioxidants provide health benefits, according to a new research.

Refined sugars and acids found in soda and citrus juice promote tooth erosion, which wears away the hard part of the teeth, or the enamel. Once tooth enamel is lost, it’s gone forever.

However, brewed tea is a beverage that does not produce such irreversible results.

Apart from tasting good, brewed tea has many health benefits. Tea is loaded with natural antioxidants, which are thought to decrease incidence of cancer, cardiovascular disease, and diabetes.

For the study, lead author Mohamed A. Bassiouny, DMD, BDS, MSc, PhD, compared green and black tea to soda and orange juice in terms of their short- and long-term erosive effect on human teeth.

The study found that the erosive effect of tea was similar to that of water, which has no erosive effect. And, when comparing green versus black, he discovered that there is a better option among those as well.

“When we look at tea and read about the benefits, it’s amazing-not because green tea is ‘the in thing’-but because there are advantages,” Bassiouny said.

He added that much research done overseas, in countries such as Japan and Europe, found that green tea was identified to being superior over black due to its natural flavonoids (plant nutrients) and antioxidants.

Experts suggest drinking drink tea without additives such as milk, lemon, or sugar because they combine with tea’s natural flavonoids and decrease the benefits.

The also suggest to stay away from pre-packaged iced teas because they contain citric acid and high amounts of sugars. It does not matter whether the tea is warm or cold-as long as it is home brewed without additives.

Kenton Ross, DMD, FAGD, AGD spokesperson, sees patients’ erosion problems on a daily basis in his practice. “This study clearly shows that brewed teas resulted in dramatically less enamel loss than soft drinks and acidic juices. I would highly recommend patients choose tea as an alternative to more erosive drinks like soda and fruit juice.”

The study is published in the July/August issue of General Dentistry, the clinical, peer-reviewed journal of the Academy of General Dentistry (AGD).

An Orange A Day Keeps Wrinkles Away

An orange a day may actually keep your wrinkles away. An interesting study has revealed that regular intake of foods rich in Vitamin C helps prevent ageing of skin.

Vitamin C, also know as ascorbic acid, is found in a wide variety of fruit and vegetables. Good sources include peppers, broccoli, brussels sprouts, oranges, kiwi fruit, strawberries, tomatoes, leafy greens, papaya, mango, watermelon, cauliflower, cabbage, raspberries and pineapples.

British scientists examined links between nutrient intake and skin ageing in 4,025 women aged 40-74 years using data from the first National Health and Nutrition Examination Survey. All the women had extensive dermatologic examinations designed to evaluate skin wrinkling and other aspects of skin ageing and also completed a survey listing all the foods they ate in a particular day.

Ageing of the skin was defined as having a wrinkled appearance, senile dryness and skin atrophy.

The study by nutritional epidemiologist Maeve C Cosgrove and other researchers found that those who ate plenty of Vitamin C-rich foods had fewer wrinkles than people whose diets contained little of the vitamin. “Vitamin C is an antioxidant that has been shown to play a role in the synthesis of collagen, the protein that helps keep skin elastic. Our findings add evidence to a predominately supplement and topical application-based hypothesis that what we eat affects our skin-ageing appearance,” according to Cosgrove.

“This is one of the first studies to examine the impact of nutrients from foods rather than supplements on skin ageing. Diets rich in Omega-6 fatty acid were found to be associated with less skin ageing from dryness and thinning while higher fat diets and those higher in carbohydrates were found to be linked to more wrinkling,” Cosgrove added. Vitamin C, a water-soluble vitamin, is important in forming collagen, a protein that gives structure to bones, cartilage, muscle, and blood vessels.
