Molars and premolars have grooves and crevices (which dentists call pits and fissures). Food can get stuck in these crevices. Some crevices are so deep that the bristles of a toothbrush can't reach into them. Pits and fissures provide the perfect environment for bacteria to grow and cause cavities. Sealants help to prevent this from happening. They cover the grooves and crevices so that food cannot get into them.
Not only are sealants very effective, they cost a lot less than filling cavities.
Most dentists recommend that sealants be applied to each permanent molar as soon as possible. This can be when the tooth is only partially erupted into the mouth. However, it can be done only if the tooth can be kept dry and free of saliva during the application process.
If your child is at high risk of cavities, your dentist may decide to seal your child's premolars, or bicuspids, as well. The premolars are the teeth directly in front of the molars.
Dentists normally don't suggest sealants for primary (baby) teeth. However, sealants can be beneficial for children who have a lot of cavities or are at high risk of dental disease.
Sealants sometimes are used in adults who are at increased risk of developing cavities. Your dentist can recommend whether this procedure is appropriate for you.
Your child's dentist will check the sealants during your child's routine checkups. If necessary, the sealants can be replaced.
Remember, sealants work well, but they can't keep your child cavity free without some help. Good oral care at home is still very important. It's also important for adults who have received sealants to continue to practice good oral hygiene by brushing twice a day, flossing at least once a day, and visiting a dentist regularly.
