Dental Sealants: How They Work

Have you observed that your posterior teeth, including your premolars and molars, differ in appearance from your other teeth, not only because they are larger, but also because they contain ridges known as cusps? These cusps play a crucial role in the grinding and chewing of food to facilitate digestion. However, the recessed areas between the cusps can trap food debris and bacteria, potentially leading to tooth decay. These areas can be difficult to clean with a toothbrush, highlighting the need for additional protective measures.

At our dental clinic, we offer dental sealants as a preventative measure to safeguard your back teeth. These thin plastic coatings create a barrier that prevents harmful substances from contacting the natural tooth enamel, reducing the risk of cavities. After ensuring that the tooth is clean and dry, we use a mild acid solution to create abrasions on the surface, which promotes the strong adherence of the sealant to the tooth. We then apply the sealant and either let it dry or expedite the process using a special light. Once in place, dental sealants can provide approximately ten years of protection.

Although dental sealants are most effective for new molars and premolars, making children under the age of thirteen the most suitable candidates, anyone without cavities or a high risk of tooth decay on their back teeth can receive them. We invite you to visit Elegant Dental Clinic in Edina, MN, to learn more about the benefits of dental sealants. Please schedule an appointment with our team.
