Many behaviors associated with eating disorders, including anorexia nervosa and bulimia nervosa, have an adverse effect on your oral health. Repeated vomiting, common in patients who suffer from bulimia, releases dangerous stomach acids that can cause cavities, erode tooth enamel, and cause tooth discoloration and even tooth loss. Eating disorders can also affect the fit of your fillings and braces.
After episodic vomiting, brushing can do more harm than good. Instead, rinse your mouth thoroughly with a neutral solution. This solution could be as simple as mixing together water and baking soda.
