Sealants are applied to the chewing surfaces (pits and fissures) of the molar teeth. This is the most common site for cavities to form. The sealants help to seal the hard to clean areas of the back teeth off to avoid plaque, bacteria, and food from trapping there. The application is fast and comfortable and can protect the teeth for many years. However, not all teeth need sealants. Dr. Mathews will evaluate the molars to see if they would be beneficial for your child.
