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.
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.
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.
The six-year and twelve-year molars are the classic candidates, ideally sealed soon after they come in.
Some tooth anatomy naturally has deeper, harder-to-clean pits, a quick check at your exam tells us who this fits.
Kids or adults who've had several cavities on molars benefit from the extra layer of protection.
Sealing molars before orthodontic treatment protects them during a stretch when brushing gets harder.
If a back molar has never been filled and still has its natural deep grooves, it can still be sealed.
Anyone who has a harder time thoroughly brushing back molars, young kids, some adults with limited mobility, gets extra benefit.
We clean the tooth's chewing surface thoroughly and keep it dry, since moisture can keep the sealant from bonding properly.
A mild etching gel roughens the enamel slightly so the sealant grips well, then we rinse and dry the tooth again.
The liquid resin is painted directly into the grooves of the tooth, flowing into every pit before it's set.
A curing light hardens the sealant in seconds. We check the bite feels normal and the coating is smooth before you go.
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.

Book ConsultationNo. 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.
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.
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.
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.
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.
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.
If your child's back molars have come in, or you've had a few too many cavities yourself, sealants are a quick, low-cost way to get ahead of the next one.
