What Are Dental Sealants and How Do They Work?
Dental sealants are thin, protective coatings that are applied to the chewing surfaces of the back teeth (molars and premolars) to help prevent cavities. These teeth are particularly vulnerable to decay because of their deep grooves and ridges, which can trap food and bacteria. The sealant material is typically a plastic resin that bonds directly to the tooth enamel, creating a smooth, durable surface. Once applied, dental sealants act as a barrier, preventing plaque and food particles from getting stuck in the grooves, which reduces the risk of tooth decay. The process of applying sealants is quick, painless, and non-invasive, making it a popular preventive treatment for children and adults alike.
The application of dental sealants involves cleaning and drying the tooth surface before applying a gel to prepare the tooth for bonding. Once the tooth is ready, the sealant is painted onto the surface, and a special light is used to harden it. This process takes only a few minutes, and the result is a clear, protective coating that blends with the natural color of the tooth. Dental sealants are an effective preventative measure, particularly for those who are prone to cavities, as they help maintain the health of the teeth for years to come.
