Most cavities in children don’t form where parents expect. They don’t start on the smooth front teeth that get brushed twice a day. They start deep inside the narrow grooves of the back molars — grooves so tight that a toothbrush bristle physically cannot reach the bottom.
That’s the problem dental sealants solve. And for most school-age children in Concord, they’re one of the highest-value preventive steps a parent can take.
What are dental sealants?
A dental sealant is a thin protective coating — usually a tooth-colored resin — applied to the chewing surfaces of the back teeth. Once painted on and hardened with a curing light, it fills in the deep pits and fissures where decay most commonly starts, creating a smooth surface that’s easy to clean and resistant to acid attack.
The procedure takes just a few minutes per tooth. There’s no drilling, no injection, and no discomfort. The tooth is cleaned, lightly conditioned, coated, and cured — that’s it.
Which teeth get sealants and when?
Sealants are most commonly applied to:
- Permanent first molars — erupt around age 6
- Permanent second molars — erupt around age 12
The American Academy of Pediatric Dentistry recommends sealing these teeth as soon as they’ve fully erupted. The reasoning is straightforward: a newly erupted molar that gets sealed before any decay begins can stay protected for years. A molar that already has a cavity cannot be sealed — it needs treatment first.
In some cases, sealants may also be appropriate for baby molars in children at high cavity risk. Dr. Yasmine Zaeni evaluates each child individually at every visit and recommends sealants based on tooth development, groove anatomy, and the child’s specific risk profile.
How well do they actually work?
The evidence is strong. According to the CDC, sealants prevent approximately 80% of cavities in the back teeth during the first two years after application, and continue to protect against roughly 50% for up to four years.
The American Dental Association reports that school-age children without sealants have nearly three times more cavitiesthan children who have them.
For families in Concord and surrounding areas like Clayton and Walnut Creek, that’s a meaningful reduction in the number of fillings, appointments, and anxious moments in the dental chair — for the life of those molars.

How long do sealants last?
With normal wear, sealants typically last 5 to 10 years. They’re checked at every routine visit, and any area that has worn thin or chipped can be touched up or reapplied.
An intact sealant is actively protecting the tooth. A sealant that has partially come off is no longer doing its job in that area — which is one more reason consistent checkups matter even for children who have never had a cavity.
Do sealants replace brushing and flossing?
No — and this is worth being direct about. Sealants protect the chewing surfaces of the molars. They don’t cover the sides of the teeth or the spaces between them, where cavities can still form.
Brushing twice daily with fluoride toothpaste and flossing remain essential. Sealants add a layer of protection on top of those habits — they don’t replace them.
Does insurance cover sealants?
Most dental insurance plans cover sealants for children, often at 100% for permanent molars up to a certain age — typically 14 to 16. Denti-Cal, California’s Medicaid dental program, also covers sealants for eligible children at no cost to the family.
Even without insurance, the cost of sealing a molar — typically $30 to $60 per tooth — is almost always less than the cost of treating a single cavity in that same tooth.
If you’re unsure about your coverage, our front desk team can verify your benefits before your child’s appointment.

FAQ: dental sealants for kids
Are dental sealants safe?
Yes. Sealants are one of the safest treatments in pediatric dentistry — no drilling, no anesthetic, no recovery. Modern sealant materials are considered safe by both the AAPD and the ADA. If you have questions about specific materials, our team is always happy to explain exactly what we use and why.
At what age should my child get sealants?
Most children get their first sealants around age 6, when the permanent first molars come in, and again around age 12 for the second molars. The best time is shortly after each molar fully erupts, before any decay begins.
Can sealants be placed over a cavity?
No. A tooth with active decay needs to be treated before a sealant can be applied. This is why timing matters — sealing a molar early, before decay begins, gives the best long-term result.
How do I know if my child’s sealants are still intact?
We check sealants at every routine visit. You don’t need to do anything special at home — just keep your child on their regular 6-month checkup schedule and we’ll monitor them as part of the exam.
My child already has sealants from another dentist — what now?
Bring your child in for a routine visit and we’ll assess the condition of existing sealants as part of the exam. If any need to be reapplied, we’ll let you know what’s needed and why.
