Weakening Enamel

Over time, tooth enamel can wear down from years of brushing, grinding and carbohydrate-rich foods that are left on the teeth, which produce enamel-eating acids. “When the enamel becomes weak, the teeth begin to look dull and they can crack and chip,” says New York cosmetic dentist Frederick Stange, DDS. While eroded enamel can’t be replaced, you can disguise its appearance with veneers.
