What is a dental sealant?

A dental sealant is a thin plastic or resin coating painted onto the chewing surfaces of back teeth, usually molars and premolars. These surfaces have natural grooves called pits and fissures where food particles and bacteria can become trapped, leading to tooth decay even with regular brushing.

The sealant creates a smooth barrier over these vulnerable areas, making it harder for decay-causing bacteria to establish themselves. Once applied and hardened with a UV light, the coating acts as a shield for several years. Sealants are most effective when placed soon after a child's permanent molars erupt, typically between ages 6 and 14, though they can benefit people of any age with cavity risk.

The procedure is quick and painless. A dentist cleans and prepares the tooth surface, then applies the liquid sealant material directly into the grooves. No drilling or tooth removal is needed. Sealants work alongside fluoride and good oral hygiene but do not replace regular brushing, flossing, or professional checkups. They typically last 5 to 10 years and can be reapplied if wear occurs.

For parents seeking preventive care for children, dentists offering pediatric dentistry services in Ghana can assess whether sealants are appropriate for your child's teeth.
