What Are Dental Sealants?
Why Are Dental Sealants Important?
Think of dental sealants as a protective umbrella for your teeth. They shield your molars and premolars from harmful elements like sugar, bacteria, and food particles that can get trapped in the grooves and cause decay.
Sealants are a thin, smooth coating made from plastic or resin-based material, applied over the deep grooves on the chewing surfaces of your back teeth. Because they are clear or white and very thin, sealants are virtually invisible and won’t affect how your teeth feel.
How Are Sealants Applied?
Applying dental sealants is a quick, painless process. First, the teeth are thoroughly cleaned and dried. Next, a mild acidic solution is applied to help the sealant bond securely to the enamel.
Then, your dentist or hygienist carefully paints a thin layer of sealant onto each tooth being treated. To ensure the sealant hardens quickly—especially helpful for children who may get restless—we use a special curing light that sets the material in less than a minute.
Once hardened, the sealant acts as a strong barrier, protecting your teeth from bacteria and decay. The entire procedure takes only a few minutes—much less time than getting a filling!
How Long Do Dental Sealants Last?
Dental sealants are quick to apply—taking just a few minutes—but they can protect your teeth for up to 10 years or even longer in some cases. During your routine dental checkups, we’ll examine your sealants for any signs of wear or damage.
If you grind your teeth (a condition called bruxism), your sealants may wear down faster and need replacement sooner. Sealants that become chipped or damaged can be easily repaired, often in just a short appointment. Many people receive sealants as children but may let them lapse as adults—regular maintenance helps keep your teeth protected throughout life.
