By the time you're an adult, you need to consider that you may already have some form of gum disease. This is a treatable condition that can cause your gums to recede and bone loss around your teeth, exposing more of your teeth. Receding gums give bacteria more room to roam, thus putting you at risk of getting cavities below the enamel, in the roots of your teeth. If you notice more space between your teeth, bleeding gums, or loose teeth, ask your dentist to check for this condition. The American Academy of Periodontology notes findings from the Centers for Disease Control and Prevention that half of Americans 30 or older have periodontal disease. Your dentist can provide guidance to help you get back on the right track.
To protect the roots of your teeth, your dentist can paint a fluoride varnish or gel on them. You can also use a fluoride mouthwash or a prescription fluoride gel to get more fluoride onto the teeth and root surfaces. Receding gums can leave the roots of your teeth exposed, which can make your teeth sensitive, and since roots are not quite as hard as the enamel on your teeth, they can be prone to cavities.
