Brush your teeth twice a day with a fluoride toothpaste. Clean between teeth regularly, aiming for once a day. Use dental floss or a special brush or wooden or plastic pick recommended by a dental professional. Or try a floss holder, floss threader, or water flosser. Visit the dentist for routine check-ups and professional cleaning. If you are at a high risk for tooth decay (for example, if you have a dry mouth because of medicines you take), your dentist or dental hygienist may give you a fluoride treatment, such as a varnish or foam during the office visit. Or, the dentist may recommend a fluoride gel or mouth rinse for home use. If you are at higher risk for gum disease because of a medical condition (for example, diabetes), your dentist may want to see you more frequently. Drink fluoridated water. Drinking water with the right amount of fluoride protects your teeth throughout the day. Learn the fluoride content of your community’s water here or check with your water utility company.
