How Effective Are Dental Sealants at Preventing Cavities?

June 23, 2026

Dental sealants are designed to cover the deep grooves and fissures in the back teeth, which are often hard to clean and prone to decay. This simple yet powerful preventive measure can make a world of difference, especially for children and teenagers who are at high risk for cavities.

What Are Dental Sealants?

Dental sealants are made of a plastic material that bonds to the grooves and pits of the teeth, creating a smooth surface that prevents plaque and food particles from settling in hard-to-reach areas. Most commonly used on molars.

The Application Process

A quick and painless procedure taking just a few minutes per tooth: the dentist cleans and dries the tooth, applies a special preparation solution, then paints on the sealant and hardens it with a special light. Completed in one visit with no recovery time.

Benefits

  • Prevention of Cavities — Creates a barrier against plaque and bacteria
  • Cost-Effective — Reduces the need for more extensive dental work
  • Durable — Can last for several years with proper care
  • Easy Application — Quick and non-invasive for children and adults

Dental sealants work best when combined with a comprehensive oral care routine including regular check-ups.
