My mother has constant dry mouth and her dentist says it is from her medications — what can we do?

✓ Accepted answer

Medication-induced dry mouth, or xerostomia, can be managed effectively by substituting current drugs with non-drying alternatives and implementing rigorous oral care routines to prevent decay. For a 78-year-old experiencing significant symptoms and new cavities, the following strategies are most beneficial:

• Review medications with a prescriber: Many antihistamines, antidepressants, diuretics, and blood pressure medications reduce saliva flow. Ask the doctor or pharmacist if a different class of medication is available that does not impair salivary production, rather than simply stopping the current prescription abruptly.
• Use prescription or over-the-counter substitutes: Products like Biotene or Lactobacillus-based lozenges can stimulate saliva. Prescription pilocarpine or cevimeline may be prescribed specifically to increase salivary flow, though they are not suitable for everyone due to contraindications.
• Modify oral hygiene: Since saliva normally protects teeth, a fluoride toothpaste with a high concentration (1,100 to 15,000 ppm) is essential to prevent further cavities. Fluoride varnishes applied by a dentist every three to six months provide extra protection against demineralization.
• Keep the mouth moist physically: Sip water frequently throughout the day, use sugar-free gum to stimulate natural saliva, and apply a humidifier to her bedroom to prevent air-dryness during sleep. Avoid alcohol-based mouthwashes, which strip remaining moisture.
• Monitor hydration and diet: Encouraging a diet rich in fluids and avoiding acidic or sugary snacks that stick to dry teeth will significantly lower the risk of future dental damage.

These steps collectively address both the comfort and the high-risk dental environment caused by medication side effects.
