what causes tooth discoloration or loss of enamel
Tooth Erosion vs Tooth Decay or Abrasion. The tooth enamel loss caused by the acids produced by dental plaque bacteria (tooth decay) is not dental erosion. Other forms of tooth enamel loss caused by mechanical and not chemical factors are tooth abrasion and tooth attrition. Tooth erosion is a slow progressive process that leads to the loss of the protective hard tissues of the tooth caused by exposure to acids for long periods of time.
