Before we can discuss how dental sealants work, it is important to first discuss what they are. Dental sealants are thin coatings made out of plastic (and sometimes other materials) that are applied to the chewing surfaces of the teeth, providing a layer of protection against tooth decay.
Dental sealants are highly effective and are especially beneficial for children, who are very likely to develop tooth decay in the grooves of their premolars and back molars. In fact, sealing children’s permanent molars from the moment they come in can keep them entirely cavity-free.
Keep in mind, however, that dental sealants can also be applied to teeth that have early signs of tooth decay to prevent any further decay. In some cases, sealants can even be applied to baby teeth, particularly when those teeth have deep depressions that make the child vulnerable to developing cavities.
Dental sealants work by bonding into the grooves of the teeth, therein forming a protective layer over each tooth. Brushing and flossing remove food particles from the teeth, but it is more difficult to remove food and plaque from the crevices of the back teeth, especially given their shape and ragged texture. This makes them particularly prone to harboring leftover food and bacteria. Dental sealants, however, act as a protective barrier against food particles and plaque.
Dental sealants are safe and have no side effects. Another benefit of sealants is that they can protect teeth against cavities for several years. At checkups, dentists will monitor the sealant for any damage and replace as necessary.
The application of dental sealants is both quick and entirely painless. An acidic gel is placed on the teeth once they are dry. This makes it possible for a strong bond to form between the tooth and the sealant. Then, the sealant is washed off and the tooth is dried so that the sealant can be applied to the crevices of the teeth.
