Everything You Need to Know about Dental Sealants

08 November 2017 - Dental Health

Did you know that a large percentage of cavities actually begin in the grooves of your teeth? Sealants are a very effective tool for preventing tooth decay!


What is a dental sealant?

The use of a sealant helps prevent tooth decay in the grooves of your permanent molars and premolars. The dentist applies a thin layer of resin which acts as a protective coating. Sealants fill in the pits, fissures and grooves, making a smooth surface that is easy to clean with a toothbrush.


Who is it for?

Dental sealants are designed for children and teenagers whose adult teeth are coming in. They can also be used in adults who show a high risk of tooth decay.


How long does it last?

The lifespan of sealants varies according to several factors. The dentist examines the resin during check-up appointments and can replace any damaged sealants, as needed.


How is it applied?

Since there is no pain involved, the application of sealants is performed without local anesthetic. The surface of the tooth is first cleaned using toothpaste or by air abrasion, then a product is applied to make the tooth more porous. The filling material is then placed in the grooves and hardened for a few seconds.
