Can medication-related dry mouth affect my teeth?

Yes. Persistent dry mouth can increase the risk of tooth decay because saliva helps protect your teeth. It deserves attention even when the medication is otherwise helping. NIDCR dry-mouth guidance.

Mention it to both your prescriber and dentist. Small sips of water and sugar-free gum may help some people, but repeatedly sipping sugary drinks can create another problem. Your dentist can recommend appropriate protection for your teeth.

Phentermine can cause dry mouth, but that does not mean you should simply accept ongoing discomfort or change treatment on your own.
