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.
