You already do a lot to keep your child’s teeth healthy. You remind them to brush, you limit the sugary snacks (or try to), and you keep up with dental appointments. But even with all that effort, cavities are still incredibly common in kids. So it’s worth asking: should your child get dental sealants?
Sealants are a preventive coating that protects teeth from decay. For most families, they’re a straightforward way to cut cavity risk during the years when kids are most prone to them. Knowing how sealants work and when they make sense can help you decide with confidence.

What Are Dental Sealants?
Think of a dental sealant as a thin, protective raincoat for your child’s teeth. It’s a plastic-like material painted onto the chewing surfaces of the back teeth. It flows into the deep pits and grooves, seals them off, and hardens into a smooth barrier that keeps out plaque, acid, and food.
That smoother surface also makes the teeth easier to clean. A toothbrush can actually reach everything instead of skipping over tiny crevices where food gets stuck.
The Application Process: Quick, Simple, and Painless
The best part about sealants? No drills, no numbing shots. The whole process is comfortable and takes just a few minutes per tooth.
Here’s what happens:
- Cleaning: The tooth is cleaned and dried.
- Preparation: A gel is placed on the surface for a few seconds to create a slightly rough texture. This helps the sealant grip the tooth.
- Application: The sealant is painted on, flowing into all the pits and grooves.
- Curing: A blue light hardens the sealant in under a minute.
That’s it. The tooth is protected right away, and your child can eat and drink normally.
Who Should Get Sealants?
Sealants work best when applied soon after permanent molars come in, before decay gets a foothold. The two key windows are:
- Around age 6: The first permanent molars appear. This is the most common time to apply sealants.
- Around age 12: The second permanent molars arrive, and it’s another good opportunity.
Children and teenagers benefit most, but adults with deep grooves in their molars (and no existing decay or fillings) can be good candidates too.
According to the CDC, sealants prevent 80% of cavities in the back teeth, where 9 out of 10 cavities develop. That’s a significant reduction from a quick, painless procedure.
FAQs
How long do dental sealants last?
With good care, sealants can last up to 10 years, though they’re most effective in the first 2 to 4 years. Your dentist will check them at regular appointments and can repair or reapply them if they chip or wear down.
Are dental sealants safe? Is there BPA in them?
The American Dental Association considers sealants very safe. Some materials contain trace amounts of BPA, but studies consistently show the exposure is extremely low, well below what people encounter through food, air, and cosmetics. The cavity prevention benefits far outweigh the minimal risk.
Does my child still need to brush and floss with sealants?
Yes. Sealants only cover the chewing surfaces of back teeth. Cavities can still form on the sides of teeth and between them. Brushing twice a day with fluoride toothpaste and flossing daily are still necessary for complete oral health.
Does dental insurance cover sealants?
Most plans cover sealants on permanent molars for children and teenagers. Adult coverage is less common. Check with your insurance provider for specifics. Even without coverage, sealants are cost-effective compared to fillings or more involved dental work later.
At what age should my child get dental sealants?
Sealants are typically recommended when permanent molars come in, around ages 6 and 12. Your dentist will evaluate the right timing based on your child’s development.
Do dental sealants hurt?
No. There’s no drilling or anesthesia involved. Most kids find it quick and comfortable.
Can my child still get cavities with sealants?
Sealants significantly reduce cavity risk on treated surfaces, but they don’t protect the entire tooth. Brushing, flossing, and regular dental visits are still important.
Are sealants only for children?
They’re most common for kids and teens, but adults with deep grooves and no existing decay or fillings can benefit too.
Supporting Your Child’s Long-Term Oral Health
Prevention beats treatment every time. Sealants are a safe, painless way to protect against one of the most common childhood health problems: tooth decay.
