Bulimia nervosa patients may encounter numerous oral health complications, primarily due to frequent vomiting. Perimyolysis and other dental erosions of the upper teeth and tongue are common due to acidity in those who self-induce vomiting, along with cavities. Although enamel erosion is irreversible, complications can be prevented with regular, gentle fluorinated oral care. Patients may also experience trauma to the soft palate and pharynx due to the use of hands or tools to induce vomiting, in addition to the damage caused by the acidic vomit itself. Those who utilize dental prosthetics may damage them in the process of purging.
