Dental Sealants Prevent Decay

Since the 1970s, fluoride has played a major role in reducing tooth decay, particularly on the smooth surfaces of teeth. However, about 90% of cavities in children still occur in the grooves and pits of the chewing surfaces, especially on back teeth like molars and premolars. To address this, dental sealants were developed as a simple and effective way to protect these vulnerable areas.

Dental sealants are thin, protective coatings made from plastic resin. They are applied to the chewing surfaces of molars and premolars, where pits and fissures are most pronounced. Once bonded to the tooth, the sealant forms a barrier that helps block out food particles, plaque, and acid that can lead to cavities.

The process is quick, painless, and noninvasive. After cleaning and drying the teeth, a dentist or hygienist paints a thin layer of sealant material onto the chewing surfaces. A curing light hardens the material within seconds. Once set, the sealant forms a durable, invisible shield that can last five years or more with proper care.

Sealants are most effective when applied shortly after a child’s permanent molars come in, typically around age 6 for the first set, and again around age 12 for the second molars. During regular dental checkups, we’ll monitor the sealants for any wear or damage and reapply them as needed. It’s a simple step that offers powerful protection and helps ensure a healthy smile for years to come.
