Sealants are a 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.
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 for about 10 years and
can be reapplied if necessary.
