Tooth Care
Sealants
Sealants are liquid coatings that harden on to the chewing
surfaces of teeth and are showing a great deal of effectiveness
in preventing cavities-even on teeth where decay has begun.
The pits and grooves of your teeth are prime areas for opportunistic
decay. Even regular brushing sometimes misses these intricate
structures on the chewing surfaces of your teeth.
The sealants are applied to the chewing surfaces and are
designed to prevent the intrusion of bacteria and other debris
into the deep crevices on the tops of teeth.
Sealants actually were developed about 50 years ago, but
didn't become commonly used until the 1970s. Today, sealants
are becoming widely popular and effective; young children
are great candidates for preventative measures like sealants
(especially on molars) because in many cases, decay has not
set in. Even on teeth where decay is present, sealants have
been shown to fight additional damage.
Application
Sealants are applied by first cleaning the tooth surface.
The procedure is followed by "etching" the tooth
with an abrasive substance, which allows the sealant to better
adhere. After the sealant is applied, a warm light source
is directed to the site to promote faster drying. Sealants
usually need re-application every five to 10 years.
