Sealants
are a thin, plastic coating that is painted on the chewing surfaces
of teeth, usually the back teeth (molars), that a Dental Office uses
to prevent tooth decay. The painted on liquid sealant quickly bonds
into the depressions and groves of the teeth, forming a protective
shield over the enamel of the tooth.
Dental
sealants are intended for young children as soon as their first teeth
come in. Decay is most common in the molars, so taking your child to
dentist’s office for sealants right when you see the molars grow in
gives your child the best chance to fight tooth decay. A child’s
first set of permanent molars grow in between ages five and seven,
while the second permanent molars come in between 11 and 14 years of
age. A sealant creates a smoother tooth surface, one that's easier to
clean and therefore more resistant to the formation of decay.
How
long do sealants last?
Once
the sealant has been placed on the teeth, it may last for years.
Expect to have your dentist check the sealant at every visit to the
office. They will look at the sealant and determine if it needs to be
replaced. Sealants need to be checked for chipping or wear.
Procedure
Applying
sealants is a simple, pain-free procedure that is done quickly. By
bonding dental sealant into the grooves of a tooth, a dentist can
make a tooth's surface smoother. As a result, there are no longer any
locations where the bristles of a toothbrush can't reach and clean.
The tooth is now at less risk for developing a cavity.
For
starters, the teeth are cleaned carefully, and then dried with an
absorbent material. A mild acid solution is applied to them to
roughen them slightly. This is done so the sealant can bond properly
to the teeth. Then the teeth are rinsed and dried, and the sealant
material is painted on and dried with a special light.
Molars
are susceptible to decay early on, which is why sealants may be a
good option for your children’s first set of teeth.
