Your molars and premolars can be hard to reach and hard to clean due to their grooved surface. These teeth can be prone to cavities and decay, so dental sealants are often applied to tooth surfaces. Dental sealants are plastic coatings that are put on the surface of the tooth, that is usually used for chewing, to help protect the molars and premolars from decay.
Since molar and premolar teeth have grooves and are typically used for chewing, it makes them vulnerable to decay. These grooves are deep, difficult to clean, and can be narrower than even one bristle of a toothbrusha toothbrush. Plaque builds up in these areas, and the acid from bacteria in this plaque wears down tooth enamel and cavities may develop. Dental sealants provide extra protection for this grooved area by providing a smooth surface covering the area.

Dental sealants are usually placed on permanent molars once the chewing surface of the teeth has emerged completely from inside of the gums, which is typically around 11-13 years of age. The dental sealant will help protect this tooth. These teeth are not always kept, but if they are, they should be covered with a dental sealant just as regular molars are.
Wisdom teeth, however, come in between 17-25 years of age and are not always kept. But if they are, they should be covered with a dental sealant just as regular molars are.
Why Only On Molars and Premolars?
Dental sealants are usually only put on the chewing surfaces of premolar and molar teeth because these are the only teeth with deep grooves. They can be put on other teeth that have deep grooves, but this is uncommon. Dental sealants are often put on teeth when a child is in their pre-teens, who are just getting their adult teeth. However, they may be put on a child’s baby teeth in order to shield them from cavities.
How It Works
At first, the tooth surface is cleaned with a paste by your dentist or hygienist. The tooth is then washed with water and dried. An acidic solution is placed on the grooved area of the tooth surface for a few seconds before being rinsed off. This creates small microscopic areas and a rough surface on the tooth. The rough surface enables the dental sealant to attach to the tooth.
After the tooth dries, a liquid dental sealant is placed on the tooth and hardens. Dental sealants are hardened by using a light that hardens the dental sealant. Once the dental sealant has hardened it becomes a hard plastic coating that will protect teeth and the grooves on the teeth from any decay. These sealants can last for a number of years, but If necessary, can be replaced.
