Some of the most effective tools in dentistry are also the most straightforward ones, and dental sealants are a perfect example. They take only minutes to apply, require no drilling or anesthesia, and can protect teeth from cavities for years. For parents looking for a proactive way to support their child’s oral health, or for adults who want an added layer of protection on vulnerable back teeth, sealants are one of the most practical preventive measures available.
At Newton Smile Centre, sealants are a regular part of how we approach comprehensive care for patients of all ages. As part of our dental services in Newton, MA, we recommend them not because they’re a quick fix, but because the evidence behind them is strong and the benefit to long-term oral health is real. Dr. Walid Benaissa and our team believe in showing patients everything we see and giving guidance the way we would for our own family, and sealants are one recommendation we consistently stand behind.
What Are Dental Sealants?
Dental sealants are thin, plastic coatings painted onto the chewing surfaces of the back teeth, primarily the molars and premolars. These surfaces have deep pits and grooves that trap food particles and bacteria, making them particularly susceptible to decay. Even thorough brushing does not always reach into every groove, which is why the back teeth account for the majority of cavities in both children and adults.
Once applied, a sealant bonds directly to the tooth and hardens to form a smooth, protective barrier. The procedure is quick and completely painless. After the tooth is cleaned and dried, the sealant is painted on and either air-dried or cured with a small light. There is no recovery time, and patients can eat and drink normally right after the appointment.
Who Should Get Dental Sealants?
Sealants are most commonly associated with children, and for good reason. The first permanent molars typically come in around age six, and the second set arrives around age twelve. Applying sealants shortly after these teeth erupt gives them protection during the years when cavity risk tends to be highest. According to the Centers for Disease Control and Prevention, dental sealants protect against cavities for many years and are one of the most effective interventions available for children’s oral health.
That said, sealants are not exclusively a childhood treatment. Adults with deep grooves in their back teeth and no existing decay or fillings may also benefit from them. During your professional cleaning and exam, we assess whether sealants make sense for you or your child based on the specific anatomy of the teeth and individual cavity risk factors.
How Sealants Fit Into a Broader Preventive Plan
Sealants work best as part of a complete approach to preventive care rather than as a standalone solution. They protect the chewing surfaces of the back teeth, but they do not cover the sides or the areas between teeth, which is where flossing and fluoride come in. Patients who receive sealants are encouraged to maintain consistent at-home hygiene habits and keep up with their regular checkups.
Understanding how diet affects cavity risk is equally important for patients of all ages. Our post on sugar and childhood cavities explains why certain foods create a higher-risk environment for decay, even when sealants are in place.
A few things we consider when recommending sealants as part of a preventive plan include:
- Cavity history: Children or adults with a pattern of decay are strong candidates
- Tooth anatomy: Deeper grooves and pits create more surface area for bacteria to collect
- Age and eruption stage: Newly erupted molars benefit most from early protection
- Fluoride exposure: Patients with lower fluoride intake may need additional coverage
- Current restorations: Teeth with existing fillings or decay are not candidates for sealants
Each patient’s situation is different, and we use these factors together to make a recommendation that fits your specific needs. For parents who want a broader guide to keeping their child’s mouth healthy, our parent’s guide to cavity prevention covers the full picture of preventive care, from brushing and flossing to diet and regular visits.
Pairing Sealants With Other Preventive Treatments
We often recommend sealants alongside fluoride treatment, which strengthens the enamel across all tooth surfaces and provides a complementary layer of protection. Together, these two treatments address different vulnerabilities: sealants block out bacteria in the grooves of back teeth, while fluoride works to reinforce the mineral structure of the enamel overall. For patients at a higher risk for decay, this combination can make a meaningful difference in keeping dental fillings and more involved restorative work off the table for years to come. To understand more about how fluoride works alongside sealants, see our post on what fluoride does for our teeth.
We also take the time to review brushing and flossing techniques with patients at each visit, so the protective work we do in the chair is supported by strong habits at home. That education piece matters as much to us as the treatment itself.

Frequently Asked Questions About Dental Sealants
How long do dental sealants last?
Dental sealants typically last between five and ten years, though they can remain intact longer with proper care. We check their condition at every routine visit and can reapply them if they show signs of wear, chipping, or coming loose. Regular checkups are the best way to ensure sealants are still providing full coverage.
Are dental sealants safe for children?
Yes. Dental sealants are considered safe and have been used in pediatric dentistry for decades. They are endorsed by the American Dental Association and the Centers for Disease Control and Prevention as one of the most effective preventive measures available for children. The application process involves no drilling, no anesthesia, and no discomfort.
Does getting dental sealants hurt?
No. Applying dental sealants is a completely painless procedure that takes only a few minutes per tooth. The tooth is cleaned, dried, and treated with a mild solution that helps the sealant bond, then the sealant material is painted on and hardened with a small curing light. Patients can eat and drink normally as soon as the appointment is over.
Can adults get dental sealants?
Yes. Adults can benefit from sealants if their back teeth have deep grooves and no existing decay or fillings. Sealants are most commonly placed on children’s newly erupted molars, but adults who have never had cavities in certain teeth and have pronounced groove anatomy are good candidates. We assess this during your regular exam and cleaning.
Do sealants replace brushing and flossing?
No. Sealants protect the chewing surfaces of back teeth, but they do not cover the sides of teeth or the spaces between them. Cavities can still form on smooth surfaces and between teeth where sealants provide no coverage. Brushing twice daily, flossing, and keeping up with regular dental visits remain essential alongside sealants for complete cavity protection.
