Sealants in Purcellville, VA

Some areas of teeth, especially the deep grooves and pits on back molars, are difficult to clean thoroughly and are more prone to cavities. Dental sealants provide a thin, protective coating that shields these vulnerable surfaces from food particles and bacteria. At South Fork Dentistry in Purcellville, VA, Dr. Simren Singh often recommends sealants for children, teens, and adults at higher risk of decay, helping to prevent cavities before they start and maintain long-term oral health.



Applying sealants is quick, painless, and can last for several years with proper care. By creating a smooth surface over the chewing areas, sealants make teeth easier to clean and significantly reduce the risk of cavities. Used as part of a preventive dental plan, sealants help protect your smile and save you from more extensive dental treatments in the future. With Dr. Singh’s gentle and patient-focused approach, South Fork Dentistry ensures patients enjoy healthier, stronger smiles that last a lifetime.

FAQ SEALANTS at South Fork Dentistry

  • What are dental sealants?

    A dental sealant is like a clear coat for your tooth. It goes over some of those deep grooves that are hard to clean, keeping them smooth and preventing bacteria from entering.

  • How do dental sealants work?

    Dental sealants act like a little jacket that sits over these deep areas of your tooth, helping to prevent food and bacteria from getting into them.

  • How are dental sealants applied to teeth?

    Super easy. A chemical, similar to a little acid, is applied to the tooth to etch the surface. We then dry it off. Once the tooth is ready for the sealant, we apply it and cure it with a blue light, similar to when you get your nails done.

  • How soon can I brush my teeth after getting dental sealants?

    Immediately. Once we cure it with the curing light, you're good to go.

  • How long do dental sealants protect teeth?

    If you take really good care of them by brushing, flossing, and having regular dental visits, sealants can last up to 10 years, sometimes even longer.

  • Can dental sealants help with sensitive teeth?

    Of course. Sometimes the sensitive areas can be covered with the sealant, preventing hot and cold things from touching them, which helps with sensitivity.

  • Can you get dental sealants if you have fillings or tooth decay?

    If you already have a filling, it's too late to get a sealant. If you have decay, you should get a filling. The sealant is for a tooth that doesn't have any decay; it is just a preventative measure.

  • How much does it cost to get a dental sealant applied to my teeth?

    Good question. Sealants are generally covered by insurance for kids under the age of 15. If you schedule an appointment, we would be happy to have the team up front help you get an estimate on the cost.

  • How can I schedule an appointment to have a dental sealant applied to my teeth?
