Our teeth are constantly being covered by a sticky film called plaque. Plaque is made of different bacteria that grow on teeth. These bacteria react with sugars and starches in food to make acids and other substances that can cause tooth decay.

What is a dental sealant?
Dental sealants are a plastic resin material that is most often applied to the chewing surfaces of the premolars and molars (which are located in the back of the mouth). The material bonds to the pits and grooves and provides a barrier that protects the tooth from collecting plaque and food debris. The uneven pits and grooves are difficult to keep clean even with regular brushing. Most tooth decay occurs on the biting surfaces of teeth so dental sealants help to decrease the risk of developing cavities. A dental sealant can last several years and as long as it remains intact the chewing surface is protected. Sealants hold up well under the forces of normal chewing.

How are they applied to the tooth?
Applying dental sealants is a simple and short procedure. It is painless and rarely requires drilling or anesthesia. The chewing surfaces of the teeth are cleaning and conditioned to help the sealant bond to the tooth. Then, the sealant is painted onto the tooth and it flows deep into the pits and grooves. A special curing light is used to harden the material.

Who is a good candidate for dental sealants?
We generally recommend sealing all six and twelve year old molars once they are fully erupted. This is because the likelihood of developing decay begins as soon as the tooth appears in the mouth.

Adults can benefit from sealants as well. Prevention is always better than treatment and can save patients money in the long run.
