Tooth decay is common but highly preventable. Dental sealants, thin protective coatings on permanent teeth, help stop cavities by blocking bacteria and food from settling in hard-to-clean grooves.
Dental sealants are safe; although some contain trace amounts of BPA, the exposure is far below harmful levels and dissipates within hours. Let’s learn more about them.
What Are Dental Sealants?
Dental sealants are thin, resin-based coatings that your dentist applies to the chewing surfaces of your back teeth. These surfaces, especially on the molars and premolars, have deep grooves and pits that can trap food and plaque.
Even with good brushing and flossing, debris can linger in deep grooves. Bacteria then produce acids that wear down enamel. Sealants prevent this by covering those grooves and protecting the tooth from decay.
Your dentist will evaluate whether a tooth is a good candidate—teeth with existing decay or restorations usually cannot be sealed.
How Dental Sealants Work
Sealants act as invisible shields for your teeth. Once applied, the coating bonds tightly to the enamel and blocks out harmful substances. As a result, it becomes much harder for bacteria and acids to cause damage.
According to the CDC, dental sealants can reduce the risk of cavities in permanent molars by up to 80% within the first two years of application. This makes them one of the most effective preventive treatments available in modern dentistry.
Who Can Benefit from Dental Sealants?
Sealants are most often recommended for children when their permanent molars erupt around ages 6–12, but adults with deep grooves or a higher risk of cavities can benefit from them as well.
If you want to lower your risk of tooth decay and maintain a healthy smile, sealants are a smart and simple solution.
What to Expect During the Procedure
Getting dental sealants is quick, easy, and completely pain-free. Here’s what happens during a typical appointment:
- Cleaning: The dentist or hygienist thoroughly cleans and dries each tooth.
- Preparation: A gentle solution is applied to the tooth surface to help the sealant adhere.
- Application: The sealant material is painted onto the tooth.
- Curing: A special light hardens the sealant within seconds.
Afterward, you can eat and drink normally, as the sealant hardens immediately under the curing light. The procedure only takes a few minutes per tooth but offers years of protection.
How Long Do Sealants Last?
Dental sealants typically last 5-10 years, but they can wear down sooner on teeth that experience heavy chewing or grinding. During your routine dental checkups, your dentist will inspect the sealants and touch them up if needed.
Brushing twice a day, flossing daily, and visiting your dentist regularly will help your sealants last longer. This simple preventive step can save you time, money, and discomfort in the future.
Why Dental Sealants Are Worth It
