Dental sealants can be a simple and effective solution for preventing tooth decay. But what exactly are dental sealants, what do they cost and how can they benefit your oral health?

On average, dental sealants cost $40–$70 per tooth without dental insurance. However, some dental plans help cover sealants as part of their preventive care benefits.1

Here’s a closer look at the cost, the benefits and more.

What are dental sealants?

Dental sealants are thin, protective coatings made from durable plastic or resin. The coating is applied to the chewing surfaces of teeth and act like a shield against bacteria and acids that cause cavities.

Sealants are usually applied to the back teeth (molars and premolars) because they do the most chewing. These teeth also have deep grooves and pits where food and bacteria can easily get trapped.

How much do dental sealants cost?

Dental sealants typically cost $40–$70 per tooth without dental insurance. The cost can vary depending on where you live, the type of dental practice and if the procedure is for a child or adult. The type of material used (plastic or resin) can affect the price as well.1

Does dental insurance cover dental sealants?

Some dental insurance plans offer partial or full coverage, but the amount will vary, and some dental plans help cover sealants as part of their preventive care benefits.1 If dental sealant coverage is important to you, be sure to check the plan details before buying the plan.

Who should consider dental sealants?

Children and adolescents

Children of all ages can benefit from dental sealants. They can be applied to baby (primary) teeth starting at the age of 2. As kids grow older, the first molars appear around age 6 and the second molars around 12. Sealing these teeth as soon as possible can help keep them cavity-free from the start.2

Adults

Adults can benefit from sealants, especially if their molars have deep grooves or pits. In fact, young adults aged 20–34 have more untreated cavities in their back teeth than any other age group.3

The benefits of dental sealants

Cavity prevention

Dental sealants prevent cavities and block food and bacteria from settling in the chewing grooves of your teeth.  

Painless application

Applying sealants is a painless process that doesn’t require drilling, numbing or other invasive procedures.

Cost savings

While dental sealants may have an upfront cost, they can help you avoid future expenses like fillings, crowns or root canals.
