Pit and Fissure Sealants: Benefits, Procedure, and Tooth Decay Prevention

What Are Pit and Fissure Sealants?

Pit and fissure sealants are thin, protective coatings placed on the chewing surfaces of back teeth. Usually, dentists apply them to molars and premolars. These teeth have tiny grooves, called pits and fissures, where food and germs can hide. Because brushing may not reach these spots, sealants help keep them clean. In fact, pit and fissure sealants are a simple way to protect teeth from decay.

How Do Pit and Fissure Sealants Work?

First, the dentist cleans the tooth surface. Then, they paint a liquid sealant onto the grooves. The sealant quickly hardens, forming a shield over the tooth. As a result, food and germs cannot get trapped in the grooves. This barrier makes it much harder for cavities to form. In addition, sealants make cleaning teeth easier for children and adults.

Benefits of Pit and Fissure Sealants

Pit and fissure sealants offer many benefits. For example, they:

  • Help prevent tooth decay in children and adults
  • Protect hard-to-clean areas of back teeth
  • Are quick and painless to apply
  • Last for several years with proper care
  • Reduce the need for fillings and dental treatments

    • Because sealants are safe and effective, many dentists recommend them for children and teens.

    Who Should Get Pit and Fissure Sealants?

    Most often, children and teenagers benefit the most from dental sealants. However, adults with healthy back teeth and deep grooves may also need them. Usually, dentists suggest sealants for:

  • Children as soon as their first permanent molars come in (around age 6)
  • Teens with new molars or premolars
  • Adults without fillings or decay in their back teeth

    • Even so, your dentist can help decide if sealants are right for you or your child.

    The Procedure: What to Expect

    Getting pit and fissure sealants is fast and easy. Here is what happens during the visit:

  • The dentist cleans and dries the tooth.
  • They apply a gentle gel to roughen the surface. This helps the sealant stick.
  • After a few seconds, the dentist rinses off the gel and dries the tooth again.
  • Next, they paint the sealant onto the grooves.
  • Finally, a special light may be used to harden the sealant.

    • Most appointments take only a few minutes per tooth. Also, the process is painless and does not require numbing.

    Safety and Side Effects

    Sealants are very safe for children and adults. According to the CDC, allergic reactions are rare. Most people do not feel any difference after sealants are applied. However, if you notice any discomfort or the sealant feels rough, let your dentist know. They can easily adjust or repair it if needed.

    Effectiveness in Preventing Tooth Decay

    Research shows that pit and fissure sealants can lower the risk of tooth decay by up to 80% in back teeth. The CDC and WHO both recommend sealants for children and teens. Because sealants block food and germs, they are a powerful tool for preventing cavities. Even so, regular brushing and dental visits are still important.

    Aftercare and Maintenance Tips

    To keep sealants working well, follow these tips:

  • Brush your teeth twice a day with fluoride toothpaste
  • Floss daily to clean between teeth
  • Visit your dentist for regular checkups
  • Avoid biting hard objects, which can damage sealants
  • Ask your dentist to check sealants at each visit

    • Sometimes, sealants may wear down or chip. If this happens, your dentist can repair or replace them easily.
