Dental Sealants: Should Your Child Get Them? What Greensboro Parents Are Asking

If your child's dentist has mentioned dental sealants, you've probably wondered: are they really necessary? Do they work? Are they safe? These are exactly the questions Greensboro parents are asking — and they're worth answering clearly. Dental sealants for kids are one of the most effective preventive tools in dentistry, and understanding what they do (and don't do) helps you make a real decision for your child.

At Lake Jeanette Family & Implant Dentistry, we're a full-service family dental practice that sees patients of all ages — from toddlers at their first visit to adults managing complex restorative care. Preventive dentistry for kids is one of the things we care most about, because the habits and care decisions you make early make a real difference later.

What Are Dental Sealants?

Dental sealants are thin, protective coatings applied to the chewing surfaces of the back teeth — the molars and premolars. These surfaces have deep grooves and pits that trap food particles and bacteria, making them especially prone to cavities even in kids who brush well. Sealants fill in those grooves and create a smooth surface that's much easier to clean.

The application is quick and painless. We clean and dry the tooth, apply a gel to help the sealant bond, rinse it, dry the tooth again, and paint on the sealant material. A curing light hardens it in seconds. That's it — no drilling, no numbing, no recovery time.

Do Dental Sealants Actually Work?

The short answer: yes, significantly. According to the CDC, sealants prevent about 80% of cavities in the back teeth, where 9 out of 10 cavities in children occur. Children without sealants are roughly three times more likely to develop cavities in their molars than children with them.

That doesn't mean sealants replace brushing, flossing, or regular cleanings — they don't. Sealants protect the chewing surfaces of back teeth, but the sides of teeth, the gumline, and the spaces between teeth still need regular care. Think of sealants as an extra layer of protection on the part of the tooth most likely to develop a cavity, not a substitute for good hygiene.

When Should Kids Get Dental Sealants?

Timing matters. The ideal window is right after a permanent molar comes in, before any decay has a chance to start. For most children, that means:

• First permanent molars typically come in around age 6 — this is the most common time for a first sealant

• Second permanent molars typically come in around age 12 — a second round of sealants is usually recommended at this point

• Premolars (bicuspids) may also benefit from sealants, especially in cavity-prone kids

We check the condition of sealants at every routine cleaning appointment. They typically last 5 to 10 years with normal wear, and we can reapply them if needed. We use digital X-rays and careful visual exams to make sure we're seeing the full picture — not just the surfaces that are easy to check, but everything that could be developing underneath.

Are Dental Sealants Safe?

This is the question we hear most often from parents, and it's a fair one. Some older sealants contained small amounts of BPA (bisphenol A), which raised concerns. The current evidence — including guidance from the American Dental Association and the American Academy of Pediatric Dentistry — indicates that the trace exposure from sealants is very low and not considered a health risk. Modern sealants are also formulated to minimize BPA precursors.

If you have concerns about materials, we're always happy to talk through what we use and why. That's part of how we work — we walk you through what we're recommending and what it involves before we do anything, so you're making an informed decision, not just going along with something.

Does Insurance Cover Dental Sealants for Kids in Greensboro?

Most dental insurance plans cover sealants for children, typically up to age 14 or 16, because they're considered a preventive treatment. Coverage varies by plan, so our front desk team will check your specific benefits before the appointment. We also work with CareCredit and Sunbit for families who need flexible financing options.

We see families from across Greensboro and the surrounding Piedmont Triad — including Summerfield and Oak Ridge, which are just a short drive from our office, and Burlington. If you've been looking for a dental home for your kids and your whole family, we'd love to meet you.

Frequently Asked Questions About Dental Sealants for Kids

At what age should my child get dental sealants?

Most children benefit from sealants around age 6 when their first permanent molars come in, and again around age 12 for their second set. We'll check at each cleaning whether a new tooth has come in and is ready for a sealant.

Do sealants hurt to get?

No. The process involves no drilling and no numbing. We clean the tooth, apply the sealant material, and harden it with a curing light. Most kids barely notice it's happening. The whole thing takes a few minutes per tooth.

Can adults get dental sealants too?

Yes, though they're most effective when applied to decay-free teeth. Adults who have cavity-prone back teeth and no existing fillings or decay in those areas can be good candidates. Ask us at your next cleaning if it might make sense for you.
