Which option best describes the oral side effects associated with antidepressant medication?

• A. Xerostomia
• B. Bruxism
• C. None
• D. Xerostomia and Bruxism

Answer: (D)

Antidepressants commonly affect the mouth in two ways: drying it out and increasing teeth grinding. Dry mouth happens because many antidepressants have anticholinergic effects or otherwise reduce saliva production. Saliva helps wash away acids and debris, so less saliva raises the risk of cavities, gum disease, and oral infections, making xerostomia a frequent and clinically important side effect. Bruxism, or teeth grinding, is also linked to several antidepressants, especially SSRIs, which can alter sleep-related muscle activity and promote clenching or grinding during the night. This can wear enamel, cause tooth sensitivity, and jaw pain or headaches. Because both effects can occur with antidepressant therapy, the option that includes both xerostomia and bruxism best describes the oral side effects. If these issues arise, coordinate with the prescribing clinician and implement oral health strategies such as saliva substitutes or hydration, good oral hygiene, fluoride products, and, for bruxism, a night guard or adjustments to the medication if feasible.
