Bruxism remains the most common cause oftooth wear. This disorder, sometimes caused by anxiety, sometimes by an imbalance between the upper and lower jaws, is characterized by repeated rubbing of the teeth. If the problem persists over time, it can, depending on its extent, lead to abrasion of the occlusal surfaces of the teeth. As these are the surfaces used for chewing, the damage caused can have both aesthetic and functional consequences. Another possible cause of wear is, indirectly, anorexia. In fact, repeated vomiting can causewear to tooth enamel due to the acid present. Teeth will then be more sensitive to the consumption of acidic foods and beverages such as soft drinks, coffee, etc., which tends to reinforce the phenomenon. Finally, brushing teeth too aggressively can, in some cases, prematurely wear away enamel. Worn teeth are also more vulnerable to attack by bacteria and acids, regardless of the quality of brushing. In all cases, therefore, it’s essential to treat the causes and consult a dentist to repair the damage and prevent further wear.
