Dental sealants

Dental sealants

Dental sealants are basically thin plastic material coverings which cover and protect the teeth against bacteria which can cause tooth decay in the future. Dental sealants are usually applied on the back teeth, on the chewing surface. These teeth are called the premolars and molars. This is the area which is mostly used while chewing and it is the area mostly affected by bacteria as well.

The bacteria in the oral cavity have a tendency to produce a special type of acid. This acid along with the plaque on the teeth, gradually start damaging the enamel. The enamel is the outer layer of the teeth. Dental sealants are applied to protect the enamel against the acid produced by the bacteria and from plaque.

Although proper brushing and flossing can remove the plaque and food particles from the teeth and clean the oral cavity, not all areas are easily reachable by brush bristles and flossing. Such susceptible areas can therefore be effectively sheltered with the use of dental sealants.

The process of applying dental sealants is not too complex. The tooth or teeth which need to be sealed are first cleaned properly by the dental hygienist. They are then roughened on the chewing surface,  this is done so that the dental sealant sticks to the tooth. The dental sealant is then painted on and fixes to the tooth enamel. Once hardened, the sealant becomes completely attached and fixed to the tooth.

Dental sealants have the potential to hold up and resist normal chewing and can remain intact usually for several years. Frequent visits to the dentist are necessary so that the dentist can evaluate the condition of the dental sealant and initiate the reapplication process, if required. Dental sealants are ideal for children and teenagers because their teeth are in much better health than adults, therefore getting dental sealants applied at this age will ensure that their oral health is maintained throughout life.
