Topic Overview
A dental sealant is a clear or white, liquid-plastic material put on
the chewing surfaces of the back teeth. The sealant bonds into the depressions
and grooves (pits and fissures) of teeth and protects them from
and
. Although children and teens usually use
sealants, adults can use them, too.
To put in a sealant, your dentist or dental hygienist will place a
cotton roll around your teeth to absorb saliva and prevent moisture from
getting on the teeth. A sheet of rubber (rubber dam) may be used to isolate the
teeth. The dentist, dental hygienist, or a dental assistant will first apply
the solution that will glue the sealant to the tooth. After about a minute, he
or she will rinse off the excess glue, dry your teeth, and put on the sealant.
One type of sealant hardens very quickly through the use of a bright
light. The other hardens more gradually.
Sealants may wear down over a period of years. Your dentist should
check them regularly and reapply them if needed.
