Why it's done

Regular dental exams help protect not just your oral health, but also your overall health. For instance, signs and symptoms of some systemic diseases, such as rheumatoid arthritis, lupus and diabetes, might show up in the mouth first. If your hygienist or dentist finds indications of disease, he or she will suggest that you see your doctor.

Also, the exam gives your dentist a chance to provide tips on caring for your teeth and to detect oral health problems early — when they're most treatable.

When to have a dental exam

The American Dental Association recommends that adults schedule regular dental exams at intervals determined by a dentist.

Even if you no longer have your natural teeth, it's important to see your dentist for regular dental exams to maintain your oral health and the usefulness of your replacement teeth.
