What are dental sealants?

Dental sealants are thin, protective coatings made from resin-plastic or other dental materials that are applied to the chewing surfaces of back teeth, especially first and second molars. These teeth often have deep surface grooves where bacteria and food particles can build up, leading to plaque and cavities. Sealants help protect against the buildup of bacteria and reduce cavity risk.

How much do dental sealants cost?

Costs vary based on where you live, the number of teeth requiring sealants, and whether other oral health treatments are recommended to accompany sealant treatment. In general, dental sealants cost $20 to $95 per tooth without dental insurance.¹ Use our cost estimator tool to find a price range for dental services near you.

What does the price of dental sealants include?

The cost of a sealant typically covers cleaning and preparing the tooth surface (removing plaque, drying the tooth), applying the sealant resin or material and, if required, curing the sealant by using light to harden it.

Are dental sealants covered by my dental plan?

Most plans offer coverage for dental sealants as part of preventive care, particularly for members under the age of 18. Be sure to review the specific details of your plan and ask for a cost estimate from your dentist before you begin treatment.

How can I pay the costs not covered by my dental plan?

If you have one of the following accounts, you may be able to use those funds to cover any portion of the charge not covered by your dental plan:

• Health Savings Account (HSA): An HSA lets you set aside pre-tax money to pay for qualified medical and dental expenses. Funds roll over from year to year, but availability depends on whether your health plan qualifies. Dental sealants are typically an eligible expense—check your plan for details.
• Health Reimbursement Arrangement (HRA): Funded by your employer, an HRA can reimburse you tax-free for eligible medical and dental expenses, depending on how your plan is set up. Dental sealants are typically an eligible expense—check your plan for details.
• Flexible Spending Account (FSA): Similar to an HSA, an FSA lets you use pre-tax dollars to pay for certain health expenses. FSAs are offered through employers and typically have lower annual limits. Keep in mind that unused funds often expire at the end of the year.

It is a good idea to check with your HSA, HRA, or FSA administrator before starting treatment. Always review your specific plan to understand what is included.
