Dental sealants are used to protect the molars and premolars from the decay. Sealants are the plastic coatings and they are placed on the outer surface of the back teeth. Molars are the permanent back teeth of human beings.
Why dental sealants are placed on the molars and premolars?
The back teeth (molar and premolar) have grooves. The outer layer of the molar is vulnerable. This chewing layer of the molar and premolar can easily rot. These grooves are difficult to clean. As they have narrow grooves. Due to the narrow grooves, the bristle of the toothbrush cannot reach there easily. The plaque in that grooves can destroy the outer layer or chewing layer of the molars and premolars. This plaque can develop bacteria and cavity in your back teeth. However, dental sealants are placed to protect the chewing layer of the back teeth. Fluoride can protect the outer layer of the teeth. So, you should use fluoride contained toothpaste in order to protect your teeth from the decay. Dental sealants are used as a shield for your molars and premolars. Dental sealants protect your back teeth and the chewing layer from the cavity and decay.
