Your back teeth, also known as your molars and premolars, are designed to help you chew your food. But their design also allows those teeth to trap food debris, plaque and bacteria that can lead to tooth decay. If you would like to protect those teeth from cavities, call Telegraph Dentists at 703-879-1222 to make an appointment for dental sealants in Alexandria, Virginia, with our dentists, Dr. Myvan Tran and associates.
