Which of the following is a potential oral health side effect associated with bulimia?

• A. Gum disease
• B. Headache
• C. Acne
• D. Dry skin

Answer: (A)

Bulimia often involves repeated vomiting, which brings stomach acid into the mouth. That acid wears away enamel and irritates the gum tissue, triggering inflammation and increasing the risk of gum disease (gingivitis and related gum problems). Dehydration and nutritional deficiencies common with bulimia can further reduce saliva flow and weaken gum health, compounding the issue. While headaches, acne, and dry skin can occur, they are not direct oral-health side effects in the same way gum disease is.
