Dental Sealants Dental sealants are a preventative procedure used mostly in children and teenagers; but are also effective for adults at risk of tooth decay. They are a plastic material applied to the fissured or chewing surfaces of the back teeth. Sealants are generally used in areas that are difficult to brush and keep clean, areas which allow food and bacteria to collect resulting in cavities. The sealant material seals the teeth, flowing into the pits and fissures, providing a barrier to guard against plaque invasion. The process for applying sealants does not involve freezing and can save time and money, by preventing the need for more invasive treatment at a later date. Shows deep grooves that are normally found in molars that act as a food trap. Two-thirds of all cavities occur in these narrow pits and grooves of newly erupted teeth. Shows sealant on tooth to protect the tooth surface from decay, these sealants can be white (as shown) or clear.
