Sealants act as a barrier to prevent cavities, protect the chewing surfaces of the back teeth and should be applied as a child’s permanent teeth erupt. Though typically placed on children’s teeth, adult molars can also be sealed, provided a tooth does not show evidence of decay. Thorough brushing and flossing can remove food particles and plaque from smooth surfaces, but oftentimes the toothbrush bristles cannot reach into the grooves of your posterior teeth. Sealants protect these more vulnerable areas by “sealing out” the bacteria. The procedure is fast and easy- no drilling or numbing required!
