PIT AND FISSURE SEALANT
Back teeth (molars and premolars) are mainly used for chewing and hence are more prone to the cavity. The dental pits and fixtures comprise of curvy and hollow dents, making them uneven, and an accumulation centre for germs and bacteria.
Fissure sealants are plastic-like material that is attached to the upper surface of the teeth to avoid cavities. They provide an even surface and facilitate easy cleaning. They last for many years and can be easily replaced if required.
At what age can a child get sealant?
1. If the child is between three to four years, then a sealant can be placed on the primary molars.
2. If the child is between six to seven years, then a sealant can be placed on the permanent molars.
3. If the child is between eleven to thirteen years, then a sealant can be placed on the permanent molars and premolars.
Application of sealant:
The tooth (or teeth) is cleaned thoroughly, and acid is applied to the upper surface of the tooth to roughen the surface. Then, the sealant is applied to the tooth (or teeth). Initially, it is partially solid, but when left to dry, it hardens and sticks to the upper surface of the teeth.
