Sealants on permanent molars reduce the risk of cavities by 80%.

Anyone with deep grooves in their teeth can benefit from dental sealants, including:

  • Kids with new permanent molars
  • Teens with cavity-prone teeth
  • Adults with deep grooves
  • Patients with frequent cavities
  • Anyone with food trapped on the tooth surfaces

Your dentist will check whether sealants for teeth are right for you during your visit.

Dental sealants provide an incredibly effective shield for your smile, reducing the risk of cavities on permanent molars by 80%. This painless procedure requires no drilling or numbing, making it a cost-effective alternative to fillings that protect your long-term health in just one visit.

The cost of dental sealants depends on the number of teeth being treated. Sealants are an affordable preventive treatment that can help protect teeth from cavities and future dental expenses. 

Many dental insurance plans cover 80–100% of sealants for children under 18, especially for permanent molars. Click here to check your coverage online. For uninsured patients or adults seeking sealants, Gentle Dental offers flexible payment options and financing solutions to help make preventive care more affordable. We’ll review your coverage and provide a clear cost estimate before treatment begins.

Dental sealants typically last 5 to 10 years with proper care. Your dentist checks them at every routine visit and reapplies if needed.

  • Hard or sticky foods
  • Oral hygiene at home

Hear From Our Patients

Robert

Gentle Dental Brighton

I can't say enough good things about how I was treated at Gentle Dental Brighton over the last few years but more specifically recently when I had an infected root. Dr. Meyer was exceptional not just in her skills as a dentist, but how compassionate she was to the amount of pain I was in. She helped me from start to finish and even checked on me after the root canal. Not just a great dentist but a great person.

Michel

Gentle Dental Jamaica Plain

Dr. Mancini and his staff got me in for an appointment within an hour of my call and took care of a loose, temporary cap. To my surprise they were able to “install” my permanent crown even though the appointment for that procedure was scheduled a week later. Perfect fit! Made my day. Thank you Gentle Dental Jamaica Plain!

Denise

Gentle Dental Nashua

Best dental care around! Immaculate office. Staff is exceptional and truly caring. Dr. Anthony is the Best! He understands my anxiety. I am telling everyone to request an appointment at Gentle Dental Nashua!

Tom

Gentle Dental Wakefield

Just had my last implant visit and can now smile again! The whole process went smoothly. Hats off to Dr. Amin, Dr. Colon and Sheela. All three, along with the rest of the staff, were very professional and pleasant to work with. I have been a patient at this office for 10+ years and would recommend Gentle Dental Wakefield to anyone for their next dentist appointment!

Carolyn

Gentle Dental Belmont

This is an excellent dental practice with flexible scheduling and friendly staff. Hygienists and dentists are very knowledgeable and skilled. Would also recommend their periodontist. Prices are quite reasonable as well. The Saturday hours are a huge plus at this dentist in Belmont.

Laura

Gentle Dental Cambridge

I would definitely recommend my experience at Gentle Dental Cambridge in Porter Square. A truly wonderful team of talented people! And they are paired with the most up-to-date technology. My experience was terrific! I needed a root canal and crowns in addition to a cavity filling. I was in safe hands! From start to finish, I was treated well and the procedures were completed in a timely manner.

Frequently Asked Questions

Which teeth need dental sealants?

Dental sealants are usually placed on permanent molars, since their deep grooves are the most cavity-prone. Premolars or other teeth with deep grooves may also benefit. Smoother front teeth rarely need sealants. During your visit, your dentist identifies which teeth will benefit the most.

How effective are dental sealants in preventing tooth decay?

Dental sealants are one of the most effective ways to prevent cavities. On permanent molars, they cut cavity risk by 80%. They work best when paired with daily brushing, flossing, and regular dental visits to keep them in good condition and catch any wear or chipping early.

Do dental sealants wear off over time?

Yes, dental sealants wear down over time, but they often last 5 to 10 years with proper care. Your dentist examines them during routine check-ups and reapplies them if they chip or wear thin. Habits like grinding, sticky foods, and weak oral hygiene can shorten their lifespan.

Do dental sealants replace the need for brushing and flossing?

No. Dental sealants protect the chewing surfaces of teeth, but they don't cover all of your teeth or your gums. Brushing and flossing are still needed to clean between teeth, along the gumline, and on smooth surfaces. Sealants work best when paired with good daily oral hygiene.

At what age should children get dental sealants?

Most children get dental sealants between the ages of 6 and 14. The first set is usually placed at age 6 when permanent molars come in, and another round around 11 to 14 when more molars erupt. Pediatric dental sealants help protect new teeth from decay during cavity-prone years.

Are dental sealants safe?

Yes, sealants are safe. They've been used in dental care for decades and are backed by major dental organizations. The materials are tested for safety. Dental sealants for adults and children are a low-risk way to prevent cavities.

Do dental sealants hurt?

Not at all. The dental sealants process is painless from start to finish. No drilling, no needles, no anesthesia. Your dentist cleans the tooth, etches it, applies the sealant, and cures it with a light. It's quick, comfortable, and a great option for nervous kids or adults.

How long do dental sealants last?

Dental sealants usually last between 5 and 10 years with proper care. Your dentist monitors them at every check-up and reapplies them if needed. Habits like teeth grinding, eating sticky or hard foods, and skipping flossing can shorten their lifespan, so daily care matters.

Are dental sealants only for children?

While pediatric dental sealants are common, this treatment is highly effective for adults, too. Any tooth with deep grooves that trap food and plaque can benefit from the 80% reduction in cavity risk that sealants provide. It remains a fast, cost-effective preventive step for patients of any age.

Do dental sealants require special care after application?

No, dental sealants don't need special care. Just brush twice a day, floss daily, and visit your dentist regularly. Avoiding very hard or sticky foods helps them last longer. Your dentist will check the sealants at each routine visit and reapply them if any chips or wear are detected.

How are dental sealants applied at Gentle Dental?

Dental sealants at Gentle Dental are applied in a few simple steps:

  • Tooth cleaning
  • Surface etching for better bonding
  • Sealant application onto grooves
  • Hardening with a curing light

The whole process is painless and takes only a few minutes per tooth.

Can Gentle Dental place dental sealants over existing cavities?

No, dental sealants can't be placed over existing cavities. Active decay needs to be cleaned out and filled first. Once the tooth is healthy, sealants can be added to suitable surfaces to prevent future cavities. Your Gentle Dental dentist will recommend the right path forward.

Can adults get dental sealants at Gentle Dental?

Yes, adults can get dental sealants at Gentle Dental. They work well for patients with deep grooves in back teeth, frequent cavities, or food that gets stuck in molars. The application is quick and painless, and sealants offer real cavity protection for adults of all ages.

Does Gentle Dental accept insurance for dental sealants?

Yes, Gentle Dental accepts a wide range of insurance plans for dental sealants. Click here to check your coverage online, or call us, and we will be happy to confirm it before your scheduled visit.

What happens if my dental sealant chips or falls off?

Sealants can be reapplied easily. If your dental sealant chips or falls off, contact Gentle Dental to schedule a quick visit. Your dentist will clean the tooth and place a fresh sealant in minutes. Until then, brush carefully and skip hard or sticky foods on that tooth.
