Dental sealants
Dental Sealants
Dental sealants (pronunciation: /ˈdɛntəl ˈsiːlənts/) are a type of Dental treatment that is applied to the chewing surfaces of the back teeth to prevent Tooth decay.
Etymology
The term "sealant" is derived from the English word "seal", which means to close tightly or block off. In the context of dentistry, it refers to the process of sealing off the grooves and pits on the tooth surface to prevent the accumulation of Plaque and development of cavities.
Description
Dental sealants are usually made of a plastic material that is applied to the chewing surfaces of the Molar and Premolar teeth. These teeth have grooves and pits where food and bacteria can accumulate, leading to the formation of cavities. The sealant acts as a barrier, protecting the enamel from plaque and acids.
Procedure
The procedure for applying dental sealants is simple and painless. The dentist will clean the tooth surface, dry it, and then apply an acid solution to roughen it. This helps the sealant bond to the tooth. The sealant is then painted onto the tooth enamel, where it bonds directly to the tooth and hardens. Sometimes a special curing light is used to help the sealant harden.
Effectiveness
Dental sealants have been shown to be highly effective in preventing decay on the biting surfaces of teeth. They are often recommended for children and teenagers, as they are most prone to cavities in the grooves and depressions of the back teeth. However, adults without decay or fillings in their molars can also benefit from dental sealants.
