Are dental sealants covered by insurance?
Usually yes for children, often at 100% as a preventive service, but only on the teeth and ages the plan allows. A sealant (code D1351) is a thin protective resin bonded into the deep grooves of a back tooth so decay cannot start there, most often placed on a child's newly erupted permanent molars. It is billed per tooth.
100%
Children, permanent molars, age-limited
Molars only
Most plans pay sealants on first and second permanent molars, nothing else. A sealant on a premolar or a baby tooth is the parent's bill on most plans.
Age 14 to 16
Where the sealant benefit usually ends. Second molars come in around 12, so the window to seal them on the plan's dime is short.
3 years per tooth
The common repeat limit. A sealant redone on the same tooth inside that window, even after it chipped, is usually not paid.
Which teeth?
Four molars can be four separate answers: age, tooth number, prior filling, and history. One check on the code before the visit tells the desk what each pays.
What would a real check show for this patient's D1351?
Pick a sample plan and type your per-tooth fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

When D1351 is the right code
- Permanent first or second molar with no filling
- Grooves intact, no decay into the tooth
- Patient under the plan's sealant age limit
- First sealant on that tooth, or past the repeat window
Documentation payers expect
Tooth number on the claim, the patient's age, and a note that the tooth has no existing restoration. Some plans ask for a bitewing showing no decay.
D1351 or its neighbors?
- D1351
- Sealant on an unfilled permanent molar
- D1352
- Resin filling for early groove decay, high-risk patient
- D1355
- Decay-preventing agent per tooth, not a sealant
- D2391
- One-surface white filling, when decay is present
Picking the wrong neighbor is its own denial category. The chart decides, not the schedule.
Why sealants get denied
What happens after the sealants
Sealants get checked at every recall and some wear or chip. A repair or replacement inside the plan's repeat window, usually 3 years, is not paid, and by the time the window opens the child may be past the age limit. If decay starts in a sealed groove, the next code is a filling (D2391) at 80% on most plans, and the parent asks why the sealant did not prevent it. Knowing the age limit and the per-tooth history before the visit sets the expectation the right way.
D1351, quick answers
Does insurance cover sealants?
For children, most plans cover D1351 as preventive, often at 100%, on permanent first and second molars only.
Until what age are sealants covered?
Commonly through 14 to 16, but it varies by plan. The eligibility check shows this plan's age limit for the code.
How often will a plan pay to reseal a tooth?
Usually once per tooth every 3 years. A chipped sealant replaced inside that window is typically the patient's cost.
Can a sealant go on a tooth that has a filling?
Most plans will not pay for it. Sealants on restored teeth are a routine denial, whatever the reason for placing one.
Are sealants on baby teeth or premolars covered?
Rarely. Most plans limit the benefit to permanent molars, and the tooth number on the claim is checked against that rule.
