Which of the following should be avoided when managing xerostomia?

• A. Inciting medications
• B. Regular dental visits
• C. Hydration and saliva substitutes
• D. Sugar-free gum

Answer: (A)

When managing xerostomia, the focus is on minimizing factors that reduce saliva and on strategies that replenish or stimulate it. Medications known to cause dry mouth should be avoided when possible because they markedly lower salivary flow, worsening dryness and raising the risk of dental decay, infections, and mucosal irritation. If a patient needs such a drug, coordinate with the prescriber to consider alternatives or dosing adjustments and implement salivary care measures to counteract the effects. The other options are helpful: staying well hydrated and using saliva substitutes provide moisture; chewing sugar-free gum stimulates saliva production and helps neutralize acids and remove debris; and regular dental visits monitor oral health and allow timely management of complications.
