You brush your child’s teeth twice a day. You floss. And you watch their sugar intake. You’re doing all the right things. But somehow, cavities still happen. And you’re left wondering what else you could possibly do.
There’s a simple, painless, and incredibly effective tool that can significantly cut your child’s cavity risk: dental sealants. And if your child doesn’t have them yet, it’s time to learn why they’re such a big deal.
What Are Dental Sealants?
Think of a sealant like a raincoat for your child’s back teeth. Those molars have deep grooves and tiny pits on their chewing surfaces. They’re great for grinding up food. But they’re also great for trapping food particles and bacteria. And no matter how well your child brushes, those bristles just can’t reach all the way into those grooves.
That’s where sealants come in. A sealant is a thin, protective coating that we paint right onto the chewing surface of the tooth. It flows into all those little nooks and crannies and hardens into a smooth, glass-like shield. It seals out food, plaque, and bacteria. It’s literally a physical barrier against cavities.
How Does the Process Work?
Getting sealants is completely painless. No needles. No drills. And no numbing. It takes about ten minutes total.
We start by cleaning and drying the tooth. Then we apply a special gel that helps the sealant bond to the enamel. We rinse that off, dry the tooth again, and paint on the sealant. Then we use a special blue light to harden it. That’s it.
Your child can eat and drink right away. There’s no recovery time. No special care. They’ll forget they even have them.
Which Teeth Get Sealants?
We typically recommend sealants for the permanent molars. Those are the big grinding teeth in the back of the mouth. They usually come in around age six for the first set, and age twelve for the second set.
Sometimes we also seal premolars or even baby teeth if we think there’s a high risk of decay. But permanent molars are the main focus as they do the most work and have the deepest grooves.
Do Sealants Really Work?
Yes. Really, really well.
According to the CDC, sealants prevent about 80 percent of cavities in the back teeth for two years after they’re applied. And they continue to prevent about 50 percent of cavities for up to four years.
That’s huge. For kids without sealants, a cavity in a back tooth is almost a rite of passage. But with sealants, that risk drops dramatically. It’s one of the most effective preventive tools we have in our pediatric dentistry office in Mt. Airy, MD.
How Long Do They Last?
Sealants aren’t permanent. They’re tough, but they do wear down over time. Most sealants last anywhere from five to ten years.
We’ll check them at your child’s regular cleanings to make sure they’re still intact. If they’ve chipped or worn away, we can easily touch them up or reapply them. It’s quick and simple.
Does Insurance Cover Them?
Most dental insurance plans cover sealants for kids. They know that preventing a cavity is way cheaper than filling one. So they’re usually happy to pay for this kind of prevention.
Even without coverage, sealants are one of the most affordable preventive treatments out there. When you compare the cost of a sealant to a filling, it’s a no-brainer.
When Should My Child Get Them?
The perfect time to get sealants is right after those permanent molars come in. That way, we can protect them before any decay has a chance to start.
We’ll let you know when your child’s molars are ready. Usually, that happens right around their regular checkup. So you don’t even need to schedule a separate appointment.
