Eating disorders, such as anorexia nervosa, bulimia nervosa, and binge eating disorder, can significantly affect oral health. Often, the initial signs of these disorders are visible in the mouth, and dentists play a crucial role in the early identification and appropriate referral of these patients.
Common oral signs in eating disorders:
Bulimia Nervosa: Frequent self-induced vomiting exposes the teeth to stomach acids, resulting in enamel erosion. Swelling of the salivary glands may also occur, giving the jaw a more squared appearance.
Anorexia Nervosa: Although vomiting is less common, the consumption of diet beverages to suppress appetite can lead to dental erosion. Other signs include dry mouth and reduced saliva production.
Binge Eating Disorder: Excessive food consumption can cause dental wear due to increased intake of acidic and sugary foods, promoting tooth decay.
It is essential to approach this topic with sensitivity and empathy. Creating a safe and trusting environment allows patients to feel comfortable sharing personal information.
Treatment should be individualised, taking into account the specific needs of each patient. Approaches may include:
Treatment of enamel erosion: Fluoride applications to strengthen tooth enamel and the use of toothpaste for sensitive teeth.
Management of dry mouth: Recommendations to increase fluid intake and the use of saliva substitutes.
Multidisciplinary Team: When necessary, patients should be referred to psychologists, nutritionists, or physicians specialised in eating disorder management.
Oral health can reflect a person’s overall well-being. Early intervention can prevent serious complications and support effective recovery.
