Preventive Care

Block the cavity before it starts.

A sealant is a thin protective coating painted onto the deep grooves of back molars, the spots a toothbrush can't fully clean and where most childhood cavities begin.

Overview

A simple coating that stops cavities before they form.

Back molars have deep pits and grooves on their chewing surface that are naturally hard to keep clean, food and bacteria settle in there even with good brushing, because the bristles simply can't reach the bottom of the groove. That's where most cavities in kids and teens actually start.

A sealant fills those grooves with a durable resin coating, smoothing the surface so plaque and food can't get trapped in the first place. It's applied in minutes, doesn't require any drilling or numbing, and holds up well through years of chewing.

It's one of the highest-value things we do preventively: a five-minute appointment that can save a child from a filling, or several, down the road.

Is It Right For You?

Who benefits most from sealants.

Sealants are most common in kids, but they're not only for kids. At your exam we'll check the grooves on your back teeth and tell you honestly whether a sealant makes sense.

Kids With New Permanent Molars

The six-year and twelve-year molars are the classic candidates, ideally sealed soon after they come in.

Deep Grooves on Back Teeth

Some tooth anatomy naturally has deeper, harder-to-clean pits, a quick check at your exam tells us who this fits.

Cavity-Prone History

Kids or adults who've had several cavities on molars benefit from the extra layer of protection.

Teens Getting Braces

Sealing molars before orthodontic treatment protects them during a stretch when brushing gets harder.

Adults Without Existing Fillings

If a back molar has never been filled and still has its natural deep grooves, it can still be sealed.

Limited Dexterity or Access

Anyone who has a harder time thoroughly brushing back molars, young kids, some adults with limited mobility, gets extra benefit.

The Process

From clean tooth to sealed tooth.

01

Clean & Dry

We clean the tooth's chewing surface thoroughly and keep it dry, since moisture can keep the sealant from bonding properly.

02

Prep the Surface

A mild etching gel roughens the enamel slightly so the sealant grips well, then we rinse and dry the tooth again.

03

Apply the Sealant

The liquid resin is painted directly into the grooves of the tooth, flowing into every pit before it's set.

04

Cure & Check

A curing light hardens the sealant in seconds. We check the bite feels normal and the coating is smooth before you go.

Sealant vs. Filling

Why we'd rather seal a tooth than fill it.

A sealant and a filling both use similar materials, but they're solving completely different problems, one prevents damage, the other repairs it.

Sealants are inexpensive relative to almost any other dental treatment, and most insurance plans cover them for children at little to no cost, since insurers recognize how much cheaper prevention is than treating cavities later. Coverage for adult sealants varies more by plan. We'll verify your benefits and give you an exact number before we apply anything.

Common Questions

What parents ask about sealants.

Still have questions? Book a visit at any of our three offices and we'll walk you through it.

Book Consultation
Is applying a sealant painful for my child?

No. There's no drilling and no anesthetic involved, so it's one of the most comfortable things we do. Most kids handle it easily, and it takes just a few minutes per tooth.

How long do sealants last?

Most sealants last 5 to 10 years, though we check them at every routine cleaning and reapply if one has worn down or chipped. They're a low-maintenance layer of protection, not a one-time forever fix.

Do sealants replace the need for brushing and flossing?

No. Sealants protect the chewing surfaces of back molars specifically, but cavities can still form between teeth or along the gumline, so regular brushing and flossing still matter everywhere else.

At what age should my child get sealants?

Most commonly around age 6, when the first permanent molars come in, and again around age 12 for the second set. We'll check at each exam and recommend timing based on your child's specific teeth.

Can adults get sealants too?

Yes, if a back molar hasn't already been filled and still has its natural deep grooves. It's less common than in kids simply because most adults already have some dental work on those teeth.

Will insurance cover my child's sealants?

Most plans cover sealants for children at little to no out-of-pocket cost, since it's a well-recognized preventive measure. We'll verify your specific benefits before the visit.
