What are dental sealants?
The term "dental sealant" or "tooth sealant" refers to a plastic resin that a dentist bonds into the grooves of the chewing surface of a tooth as a means of helping to prevent the formation of tooth decay ("cavities").
Why are dental sealants placed on teeth?
Tooth decay is caused by the bacteria found in dental plaque (the white film that forms on a person's teeth). In general, the longer dental plaque remains on a tooth's surface the more likely it will be able to form a cavity. The idea behind brushing teeth is that dental plaque that has accumulated on a tooth's surface is scrubbed off. Some teeth however, related to aspects associated with their anatomy, are harder to clean than others.
Some back teeth, especially molars, can be difficult for a person to clean because the grooves found on their chewing surface (the tooth's "pits and fissures") are deep and narrow. Even though the person brushes their teeth not all of the dental plaque that is present is cleansed off because the individual bristles of their toothbrush are simply too large to gain access into the depths of the tooth's grooves. Because some plaque has not been cleaned away, the tooth is at risk for the formation of decay.
Typically, the dental crown procedure is completed in two stages. During the first stage, the dentist removes portions of your natural tooth’s structure to accommodate the dental crown. Surroun By bonding plastic resin (the dental sealant) into the grooves of a tooth a dentist can create a tooth surface that is smoother.
