Dry Mouth: Why It Matters More Than You Think

Hundreds of medications list dry mouth as a side effect: antihistamines, blood pressure drugs, antidepressants. Other causes include mouth breathing, dehydration, smoking, menopause, and conditions like Sjogren's syndrome or diabetes.

Without saliva's buffering, acids from food and bacteria sit against enamel longer. Patients with chronic dry mouth often develop cavities along the gumline and at root surfaces, areas that rarely decay otherwise.

Sip water constantly, chew sugar-free xylitol gum to stimulate flow, use a humidifier at night, and try saliva substitutes or prescription rinses for severe cases. Avoid alcohol-based mouthwash, caffeine, and tobacco, all of which dry tissue further.

Tell your dentist which medications you take. High-fluoride toothpaste, more frequent cleanings, and early treatment of small cavities keep dry-mouth patients out of the restorative cycle.
