A wonderful way to protect against tooth decay and cavities on your molars is by using sealants. Molars are the most susceptible to cavities because they do most of the work during chewing and are hard to reach and clean properly. Molars begin to come in between ages five and seven. A second set of molars will be coming in between ages eleven and fourteen. The best practice is to have sealants placed when molars first come in to provide protection early.
Placing a sealant requires that an adhesive is applied to your teeth. The sealant is then set over the adhesive as a liquid. It is essentially painted directly on to the tooth. That liquid will eventually harden and create a barrier that will protect the teeth from food particles, plaque and some bacteria. Typically sealants will last around ten years and they can also be reapplied if necessary.
