Dental erosion is the progressive loss of tooth enamel due to acid attacks, leading to sensitivity, discoloration, and changes in tooth shape. Causes include acidic foods and drinks, gastroesophageal reflux disease (GERD), and dry mouth. Symptoms often manifest as increased sensitivity to temperature and sugar, along with yellowing or translucency of the teeth. Early recognition is crucial to prevent severe damage and potential complications like infections or further tooth decay. Regular dental check-ups and preventive measures can help mitigate these effects.
