Dental sealants are a plastic coating that is applied to the chewing surfaces of the back teeth, where there are tiny grooves in the teeth that are so narrow that a toothbrush cannot fit into the spaces to remove the plaque. This prevents decay in these very small grooves, and they can provide 100% protection from cavities on the chewing surfaces. In addition, when dental sealants are used over very minimal decay, the decay stops progressing.


According to the most recent recommendations, children between the ages of 6 and 12 should get dental sealants on permanent molars as soon as they erupt. Very simple and painless to apply, the tooth sealant is just “painted” into the grooves of the teeth. After that a high intensity light is used to activate the liquid plastic to harden it.

Lasting anywhere from two to 10 years, the dental sealants are very durable. Your dentist should check them during your regular visits and re-applied if needed.
