Fluoride helps prevent cavities in children and adults by making the outer surface of your teeth more resistant to the acid attacks that cause tooth decay. Our dentists can apply fluoride directly to your teeth during your dental visit with a gel or foam.
Sealants are another great way to protect against tooth decay and cavities on your back teeth (molars). These are the teeth that are most vulnerable to cavities and decay because they are used in the chewing process, and are the most difficult to reach and clean. Molars first come in at around 5-7 years of age, with a second set coming in between the ages of 11-14. It is best to have a sealant placed when the molars first come in to ensure they are protected early. However, adults also can receive sealants on healthy teeth. It is more common to seal “permanent” teeth rather than “baby” teeth, but every patient has unique needs, and your dentist will recommend sealants on a case-by-case basis.
To place a sealant an adhesive is first applied to the teeth. The sealant is then placed over the adhesive as a liquid, as if it is painted right onto the tooth. The liquid then hardens and creates a barrier between your tooth and any plaque, food particles, and bacteria.
Sealants last from three to five years, although it is fairly common to see adults with sealants still intact from their childhood. A dental sealant only provides protection when it is fully intact, so if your sealants come off, let your dentist know, and schedule an appointment for your teeth to be re-sealed.
