Do children need dental sealants?


Updated January 2021

Dental sealants are a quick, easy, and relatively cheap solution for preventing cavities.  Although the idea behind sealants is not new, they’re quickly becoming the go-to treatment for kids that are at high risk for dental decay.


Sealants are a plastic material that is placed in the groovy pits and fissures of the chewing surfaces of your teeth. Furthermore, sealants are particularly the permanent molars at the back because toothbrushes can’t reach all the way into the grooves to clean well.


Kids are notoriously bad brushers. They tend to ignore brushing in the problem areas particularly in the back of the mouth. Ultimately, this leads to cavities and decay. The American Academy of Pediatric Dentistry (AAPD) recommends that children receive dental sealants as soon as their permanent molars erupt; this is when the teeth are at the highest risk for cavities.

Those who are more susceptible to cavities and decay; whether that is because they are genetically prone to cavities, don’t have great oral hygiene habits, or lack access to dental care; should consider getting dental sealants as a preventative measure. Dental Sealants help prevents up to 80% of cavities in children. Dental Sealants are most common in children ages 5-14.


Dental sealants fill in and smooth out the grooves and fissures in your teeth that tend to hide food particles and attract cavity-causing bacteria. According to the American Dental Association, sealants work by “sealing out” food and plaque…because, toothbrush bristles cannot reach all the way into the depressions and grooves.


Dental sealants can protect the teeth for up to 10 years but need to be checked and maintained frequently by a dentist for cracks or damage.  If dental sealants are worn down or broken, it is possible for decay to get under the sealant.

We recommend having the sealants evaluated every 6 months for replacement/maintenance.


Dental sealants have been shown to reduce the risk of cavities in the teeth that are covered.  Research has demonstrated that coating the biting surface of 6-year molars with a plastic sealant can reduce cavities by up to nearly 80% immediately, and up to 60% for four years or more.


If you’re a parent, you’ve probably heard the buzzword “BPA” quite a few times in recent years.  The biggest factor in the general safety of dental sealants is Bisphenol A, commonly referred to as BPA, which is a resin used in many types of plastics.  There is some evidence that BPA can be harmful to a child’s health, but it’s not conclusive.  In July of 2013, the FDA banned BPA in baby bottles and children’s drinking cups.

The sealant material we use at our office does not contain BPA or byproducts of BPA and has been FDA approved.


As with all medical and dental treatments, the cost can vary depending upon the provider and your insurance plan.

We recommend dental sealants for all six and twelve-year molars, and most insurance companies cover them as part of your child’s preventative care services.
When you bring your child in for their cleaning and check-up appointments, our staff will check to see if their molars are present. If they are, we will discuss applying sealants with you.


The application process is simple and usually takes five or ten minutes. The teeth that will be sealed are thoroughly cleaned and dried. Then the chewing surfaces are roughened with an etching solution that helps the sealants adhere to the teeth. Next, the sealant is “painted” onto the tooth. Lastly, a special curing light bonds and hardens it. Sealants last for several years and will be checked and touched up as necessary at your child’s future appointments.

Getting sealants is not painful and most children have no problem with the process. They will have their mouth propped open with a “tooth pillow” while the sealants are being applied. Most importantly, they’ll need to sit extra still. In children who have high dental anxiety or a strong gag reflex, nitrous oxide (laughing gas) can be administered during the sealant process to help them relax.

Let us know at your next dental visit if you have any questions regarding dental sealants and/or whether your child would benefit from placing sealants on their molars.
