A sealant is a thin, plastic coating applied to the chewing surface of molars, premolars and
any deep grooves (called pits and fissures) of teeth. More than 75% of dental decay begins
in these deep grooves. Teeth with these conditions are hard to clean and are very
susceptible to decay. A sealant protects the tooth by sealing deep grooves, creating a
smooth, easy to clean surface.
Sealants can protect teeth from decay for many years, but need to be checked for wear and
chip at regular dental visits.
Sealants are small, synthetic covering placed in the chewing area of the molars, premolars
and the pits and cracks of the teeth. About 75% or more of tooth decay starts in the
deep-seated canals. These are difficult to brush and are so vulnerable to decay. What a
sealant does is guard the tooth by closing the grooves, forming a soft and quick to brush
mouth area. Lasting for a long time, sealants can be very useful for protection against tooth
decay. However, sealants must be tested for any damages during regular dental check-ups.
Why sealants are needed?
• For children and teenagers – The moment the six-year molars begin to come out or any time during the
years of 6 up to 16 where children and teenagers are really susceptible to cavities.
• For adults – Tooth exteriors without decay which have deep grooves or canals.
• For baby teeth – Rarely performed if teeth have deep grooves or depressions and the child is likely to
How do sealants work?
Sealants are simply placed by the dentist or dental expert and the process does not take long as it only
consumes a few minutes for every tooth.
The teeth to be clinched are carefully cleansed, enclosed with cotton to maintain dryness on the area. A
unique mixture of liquid is laid on to the enamel exterior to make the sealant attached strongly to the
teeth. After that, the teeth are washed and dried up. Sealant substance is cautiously coated straight into
the enamel surface to envelop the deep depressions of the teeth. Moreover, the sealant will solidify right
away depending on the kind of sealant utilized.
Appropriate home care steps, a healthy habit, and constant dental check-ups will surely help in preserving
your new sealants.
