Learn about dental sealants

What Sealants Do for You
A sealant is a clear shaded plastic material that is applied to the chewing surfaces of the back teeth (premolars 
and molars), where decay occurs most often. This sealant acts as a barrier, protecting the decay prone areas of the tooth from plaque and acid.

How Sealants are Applied
Each tooth only takes a few minutes to seal. First, the teeth that will be sealed will be cleaned. The chewing surfaces are then etched (roughened) with a weak acidic solution to help the sealant adhere to the teeth. Finally, the sealant is placed onto the tooth enamel and hardened. Some sealants need a special curing light to help them harden, while others do not.

Who Should Have Sealants
Although children receive significant benefits from sealants, adults can also be at risk for pit and fissure decay and thus be candidates for sealants. Your dentist can advise you about the need for sealants. Sealants are also recommended even for those who receive topical applications of fluoride and who live in communities with 
fluoridated water. Fluoride helps fight decay on the smooth surfaces of the teeth but is least effective in pits and fissures.

How Long Do Sealants Last
When the sealant is applied, finger-like strands penetrate the pits and fissures of the tooth enamel. Although the sealant cannot be seen with the naked eye, the protective effect of these strands continues. As a result, it may be several years before another application of sealant is needed. Reapplication of the sealants will continue the protection against decay and may save the time and expense of having a tooth restored. Sealants will be checked during regular dental visits to determine if reapplication is necessary.
