Drinking water is the best thing one can do to keep your teeth safe. Keeping a bottle of water with you or have a glass of water after major meals, this helps neutralize the good acids that can break down the natural enamel on your teeth. " It acts as a natural mouthwash". says Howard S. Glazer, D.D. S., a dentist in Fort Lee, New Jersey. Also try to make sure you drink water after eating starchy foods. "The starch in potatoes breaks down into sugar, and because chips stick to your teeth, there is more risk of damage," says Dr. Glazer. Mohamed A. Bassiouny of the Temple School of Dentistry in Philadelphia, PA, and his colleagues have surmised that, Whenever possible, people should rinse their mouth with water after having a soft drink, but not brush immediately as this can further damage the acid-weakened enamel." So drinking water is the best thing one can do after eating to help protect the enamel on your teeth.
