A sealant is a resin material applied to protect the enamel from bacterial plaque in cavity prone areas
A sealant is a resin material that is usually applied to the pits and fissures of the back teeth. The sealant resin acts as a barrier, protecting the enamel from bacterial plaque in cavity prone areas. Decay will not start under a tooth sealant because the decay causing bacteria are deprived of the food they need to survive. Children are much more susceptible to tooth decay than adults. When possible, sealants should be applied to children’s teeth before decay has had a chance to begin.
Sealants are easy and painless for your dentist to apply, and it only takes a few minutes to seal each tooth. As long as the sealant remains intact, the sealed tooth surface will be protected from decay. Sealants hold up well under the force of normal chewing and usually last for several years. During your regular dental visits, your dentist will check the condition of the sealants and reapply them if necessary.
When a tooth is developing, deep groves form in the biting surfaces of the back teeth. These grooves are called “fissures”. When two or more fissures intersect, it is called a “pit”. Thorough daily brushing, flossing, and rinsing help remove food particles and bacterial plaque from the smooth surfaces of the teeth. But because toothbrush bristles cannot reach all the way into the pits and fissures, food and bacteria cannot be easily removed. Tooth sealants protect these vulnerable areas by “sealing out” plaque and food.
