Dental sealants
Dental sealants
A dental sealant is a thin, protective plastic or resin coating applied to the chewing surfaces of back teeth (molars and premolars) to prevent decay. It acts as a barrier against food and bacteria, filling deep grooves (fissures) that are hard to clean with a toothbrush.
Key Details About Dental Sealants
Primarily applied to children's permanent molars (ages 6–14) to prevent cavities, but also used for adults with deep, decay-prone grooves.
A quick, painless, non-invasive process involving cleaning, etching (roughening), painting on the resin, and hardening it with a specialized light.
Highly effective at preventing decay by up to 86%, they are durable, lasting up to 10 years, and cost-effective compared to fillings.
Why They Are Used
Molars have deep grooves that toothbrush bristles cannot reach, making them prime locations for trapping food and developing decay. Sealants create a smooth surface that is easier to keep clean. They are safe and considered a foundational component of preventive dentistry.
