A sealant is a thin plastic coating that is applied to molars and premolars to protect against decay in the deep grooves of teeth. People who have teeth with deep grooves (also known as pits and fissures) are more prone to cavities and tooth issues as the teeth are difficult to clean and more susceptible to decay.
Reasons for sealants:
- Children and Teens: Performed after their six-year molars come in, during the cavity prone years of 6-16.
- Adults: Performed if patient has tooth surfaces without decay with deep grooves or depressions.
- Baby Teeth: Occasionally done if the child has deep grooves or depressions and the child is cavity prone.
What do sealants involve?
Your dentist or hygienist will apply a sealant in one sitting — it only takes a couple of minutes per tooth. The sealant is painted onto the surface of the tooth where it will either harden automatically or with the help of a special curing light.
