Why does dry mouth cause more cavities?

Saliva neutralizes acids, washes away food particles, and remineralizes tooth enamel. Without enough of it, bacteria and acid stay in contact with teeth longer, accelerating decay — sometimes in unusual spots like the gumline or the roots.

Should I stop my medication if it is causing dry mouth?

Never stop a prescription medication without talking to the prescribing doctor. There may be an alternative, a dose adjustment, or strategies to protect your teeth while staying on the medication you need.

Are saliva substitutes worth trying?

Over-the-counter mouth rinses and gels designed for dry mouth can provide real relief for many people. They do not replace saliva, but they reduce discomfort and help protect the mouth. We can suggest specific products at your visit.

How often should I see a dentist if I have dry mouth?

People with chronic dry mouth often benefit from more frequent cleanings — every three to four months — to catch cavities early and keep the gumline clean. We tailor the schedule to your situation.

Is there anything a dentist can apply to protect my teeth?

Prescription fluoride treatments and fluoride varnishes can help strengthen enamel that is at higher risk. We will discuss whether that makes sense for you during your evaluation.

Chronic dry mouth — what it means for your teeth

Dry mouth (xerostomia) is more than a nuisance. Saliva protects your teeth and gums, so when you do not have enough of it, cavities and gum problems can develop faster than usual. Here is what to know.
