Sealants are placed in the groove of the child’s teeth to prevent cavities. They are tooth colored restorative materials that are usually placed into the grooves of the back teeth (molars, premolars, and sometimes the lingual surfaces of the anterior teeth with deep pits) to prevent cavities from forming. Sometimes children forget to brush these area, and this is an added layer of protection. Children can get these six years old and over, when the permanent teeth come in. Although you can seal baby teeth, it is better to be completed on permanent teeth.
The deep grooves on the chewing surfaces of the teeth are very hard to clean. When sealant is applied, the chewing surface of the tooth feels flatter and smoother, eliminating any hiding places, where toothbrush bristles can’t reach.
