A. Causes of Enamel Erosion
Enamel erosion occurs when acids wear away the enamel on teeth. These acids can originate from external sources, such as certain foods and beverages, or internal sources, like stomach acids. Common causes include:
° Dietary Habits: Frequent consumption of acidic foods and drinks, such as citrus fruits, soft drinks, sports drinks, and wine, can erode enamel.
° Gastroesophageal Reflux Disease (GERD): Stomach acids can reach the mouth and erode enamel in individuals with GERD.
° Frequent Vomiting: Conditions that induce regular vomiting, like bulimia or alcoholism, expose teeth to stomach acids, leading to erosion.
° Dry Mouth (Xerostomia): Saliva helps neutralize acids; reduced saliva production can increase the risk of enamel erosion.

If left untreated, enamel erosion can lead to:
° Increased Tooth Decay: Weakened enamel makes teeth more prone to cavities.
° Advanced Tooth Wear: Significant loss of tooth structure can occur, affecting appearance and function.
° Tooth Fractures: Thinned enamel increases the risk of teeth cracking or breaking.
E. Treatment of Enamel Erosion
While enamel cannot be regenerated, treatments aim to prevent further erosion and restore tooth function:
° Fluoride Treatments: Topical fluoride can strengthen remaining enamel and reduce sensitivity.
° Dental Bonding: Application of tooth-colored resin can protect damaged areas and improve aesthetics.
° Crowns or Veneers: In severe cases, coverings may be placed over affected teeth to restore appearance and function.
