If your child's dentist has mentioned dental sealants, you're not alone in wondering what they are, when to get them, and whether they're really worth it. As a parent, protecting your child's teeth from cavities is a top priority — and sealants are one of the most effective, low-risk tools available for doing exactly that. Visit GetYourDentist.com anytime to explore more dental resources for your family.
This guide answers every question parents typically ask about sealants: the right age, the procedure itself, costs, insurance coverage, and how to find a trusted dentist in Washington for your child's first appointment.
Children should typically get dental sealants between ages 6 and 14, when their first and second permanent molars erupt. In Washington, most pediatric dentists recommend sealants as soon as each molar fully comes in — usually around age 6 for the first molars and age 12 for the second molars. Early application provides the most protection during the cavity-prone years.
What Are Dental Sealants?
Dental sealants are thin, protective coatings made of plastic or resin that are painted directly onto the chewing surfaces of back teeth — mainly molars and premolars. Once applied, they harden into a shield that prevents food particles and bacteria from settling into the tiny grooves and pits of the tooth enamel.
Think of the surface of a molar like rough terrain: deep valleys and ridges are nearly impossible to clean fully with a toothbrush. Sealants fill in those valleys, making the tooth surface smooth and much easier to keep clean.
How Effective Are Dental Sealants?
The numbers are impressive. According to the Centers for Disease Control and Prevention (CDC), sealants protect against 80% of cavities in the back teeth for the first two years after application, and continue to protect against 50% of cavities for up to four years. School-age children without sealants have nearly three times more cavities than those with them.
That's a meaningful difference — especially considering that cavities in permanent teeth can lead to pain, missed school days, and costly restorative treatments down the road.
The Right Age for Dental Sealants in Washington
Timing is everything when it comes to sealants. The goal is to seal each molar as soon as it fully erupts — before decay has a chance to begin. Here's how the typical timeline looks:
| Age Range | Teeth Erupting | Sealant Recommendation |
|---|---|---|
| Ages 5–7 | First permanent molars | Highly recommended as soon as fully erupted |
| Ages 11–14 | Second permanent molars & premolars | Strongly recommended upon eruption |
| Teens (14–18) | All permanent teeth in place | Beneficial if no decay or fillings present |
| Adults | Existing molars without sealants | Possible, though less common; ask your dentist |
Washington state's school-based dental sealant programs often target children in grades 2 and 7 — roughly aligning with the two key eruption windows. If your child has missed these windows, it's still worth discussing sealants with a dentist, since healthy teeth without existing decay or fillings can still benefit.
Can Toddlers or Very Young Children Get Sealants?
Sealants are typically applied to permanent teeth, not baby teeth. However, in cases where a child has deep grooves in their primary molars and a high cavity risk, a dentist may recommend sealants on baby teeth as well. This is less common but completely safe. Your child's dentist will evaluate this based on their individual oral health history.
What Happens During a Sealant Appointment?
Good news: the process is quick, painless, and doesn't require any drilling or numbing injections. Most parents are surprised at how straightforward it is. Here's what to expect:
- Cleaning: The dentist or hygienist thoroughly cleans and dries the teeth that will receive sealants.
- Etching: A mild acidic gel is applied to roughen the enamel surface slightly, helping the sealant bond better.
- Rinsing & Drying: The gel is rinsed off and the tooth is dried again completely.
- Application: The liquid sealant material is painted onto the chewing surface of each tooth.
- Curing: A special blue light is used to harden the sealant within 60 seconds.
- Bite check: The dentist checks to make sure the sealant doesn't interfere with the child's bite.
The entire appointment typically takes 30 to 45 minutes, and children can eat and drink normally right afterward (though avoiding sticky or hard foods for the first 24 hours is a good idea).

How Long Do Sealants Last — and What Affects Their Longevity?
Dental sealants can last anywhere from 5 to 10 years with proper care. Some sealants last even longer. During each routine dental checkup, the dentist will inspect the sealants for chips or wear and can reapply them as needed.
Factors That Affect How Long Sealants Last
- Diet: Frequent consumption of hard, crunchy, or sticky foods can wear sealants down faster.
- Teeth grinding (bruxism): Children who grind their teeth at night may wear through sealants more quickly.
- Oral hygiene habits: Good brushing and flossing habits extend the life of sealants and prevent decay around the sealed areas.
- Material quality: Resin-based sealants tend to be more durable than glass ionomer types, though both are effective.
It's worth noting that even if a sealant chips or partially wears away, it still provides more protection than having no sealant at all. The dentist will advise on whether reapplication is recommended.
Cost of Dental Sealants in Washington
The cost of sealants varies by provider and location, but here's a general range parents can expect in Washington state:
| Cost Factor | Typical Range |
|---|---|
| Cost per tooth (without insurance) | $30 – $60 per tooth |
| Cost for 4 molars (without insurance) | $120 – $240 |
| With dental insurance (children's plans) | Often fully covered or at low copay |
| Washington Apple Health (Medicaid) | Covered for children under 18 in many cases |
| School-based sealant programs (WA) | Free or low/no cost for eligible children |
Does Insurance Cover Sealants in Washington?
Most dental insurance plans that include pediatric coverage will cover sealants for children up to a certain age — typically 14 or 16. Washington's Medicaid program, Washington Apple Health, covers sealants for eligible children, making them accessible even for families without private insurance.
Additionally, Washington participates in the Washington Seal Washington Kids initiative and various school-based dental programs that provide sealants at no charge to qualifying children. Contact your child's school nurse or local health department to learn about available programs in your area.
Are Dental Sealants Safe for Children?
This is one of the most common concerns parents raise, and it's a fair one. Some parents have heard about BPA (bisphenol A) in sealant materials and wondered whether it poses a health risk.
What the Research Says
The National Institute of Dental and Craniofacial Research (NIDCR) and the American Academy of Pediatric Dentistry both affirm that dental sealants are safe and the benefits far outweigh any theoretical risks. While some sealant materials contain trace amounts of BPA or BPA-related compounds, the actual exposure during application is extremely low — far below levels considered harmful.
- Studies show BPA exposure from sealants is lower than from many everyday items like plastic food containers or water bottles.
- The brief, one-time application means ongoing exposure is essentially negligible.
- BPA-free sealant formulations are available and widely used by dentists who prefer to take an extra precautionary step.
If you have concerns, ask your child's dentist specifically about the brand of sealant they use and whether BPA-free options are available at their practice.
Sealants vs. Fluoride: Do Kids Need Both?
Parents sometimes wonder whether sealants and fluoride treatments overlap in purpose. The short answer: they complement each other beautifully.
| Protection Method | How It Works | Best For |
|---|---|---|
| Dental Sealants | Physical barrier covering grooves and pits | Back teeth (molars, premolars) |
| Fluoride Treatment | Strengthens enamel and reverses early decay | All tooth surfaces, especially smooth sides |
| Both Together | Comprehensive protection across all surfaces | Maximum cavity prevention |
Most pediatric dentists recommend both treatments as part of a preventive care plan. They work on different surfaces and via different mechanisms, so together they offer much more complete protection than either alone.

Frequently Asked Questions About Kids' Dental Sealants in Washington
At what age should my child get dental sealants?
Most children should receive their first sealants around ages 6–7, when the first permanent molars erupt. A second application is typically recommended around ages 11–14 for the second molars. The sooner sealants are applied after each molar erupts, the better the protection.
Are dental sealants covered by insurance in Washington?
Yes, in most cases. Many dental insurance plans with pediatric coverage include sealants at low or no cost for children up to age 14 or 16. Washington Apple Health (Medicaid) also covers sealants for eligible children. Always verify your specific plan's benefits before the appointment.
Do dental sealants hurt?
No. The sealant process is completely painless and does not involve any drilling, injections, or removal of tooth structure. Most children tolerate the procedure very well, and the whole appointment typically takes under an hour.
How long do dental sealants last?
Sealants typically last between 5 and 10 years, though some may last longer. Your child's dentist will check them at every routine visit and recommend reapplication when necessary.
Can adults get dental sealants too?
Yes, adults can receive sealants on healthy molars that have no existing decay or fillings. However, sealants are most beneficial and most commonly applied during childhood, when cavity risk is highest and the teeth are newly erupted.
Are there any free dental sealant programs in Washington?
Yes. Washington has several school-based sealant programs that provide free or low-cost sealants to children in certain grades. Additionally, Washington Apple Health covers sealants for Medicaid-eligible children. Contact your local health department or school nurse to find programs in your area.
What's the difference between dental sealants and fillings?
Sealants are a preventive measure applied to healthy teeth before decay develops. Fillings are a restorative treatment used after decay has already caused damage. Sealants are far less invasive and significantly cheaper than fillings — which is why prevention makes such strong financial and health sense.
Can sealants be applied over existing cavities?
Sealants should not be applied over untreated cavities. However, if very early-stage decay is detected, some dentists may apply sealants to help stop progression, depending on the severity. Your dentist will evaluate each tooth individually before proceeding.
Do my child still need to brush and floss if they have sealants?
Absolutely. Sealants only protect the chewing surfaces of back teeth — they don't cover the sides, fronts, or areas between teeth. Daily brushing with fluoride toothpaste and flossing remain essential parts of your child's dental routine.
How do I know if my child needs sealants or already has them?
Your child's dentist will assess their teeth during a routine checkup and recommend sealants if appropriate. If you're unsure whether your child has sealants, the dentist or hygienist can check — sealants are usually visible as a thin, slightly shiny coating on the molars.
