What are sealants, fillings, and crowns?
A sealant is a clear or shaded plastic material that is applied to the chewing surfaces (grooves) for the back teeth (premolars and molars), where most cavities in children can form. This sealant acts as a barrier to food, plaque, and acid, thus protecting the decay-prone areas of the teeth. However, cavities between the teeth are not protected by sealants. As long as there is no cavity in the tooth, sealants will be recommended for all children.
If your child has a cavity, a filling is placed after the cavity is removed. Most of the time, the filling is a tooth colored (white) filling, but there are certain situations in which a silver filling is necessary. In our practice, when a tooth needs a filling, a sealant is placed over the filling and the remaining tooth for added protection.
In a primary tooth, if a cavity is too large to restore with a filling, a crown may be recommend or the tooth may need to come out. If the cavity is too large and has involved the nerve of the tooth, then the nerve will be removed (pulpotomy) along with the cavity, and a crown will be placed. A crown can either be tooth colored or stainless steel. For front teeth, white crowns are routinely used for esthetics. For back teeth, stainless steel crowns are used for their durability and longevity. The purpose of the crown is to help provide structure for the tooth, to help maintain space for permanent teeth to erupt properly, and to help protect the remaining tooth.
