Dental Sealants for Kids in Arlington, VA
A simple, painless treatment that protects your child’s back teeth from cavities — before they ever start.
What Are Dental Sealants?
Dental sealants are thin, protective coatings painted onto the chewing surfaces of your child’s back teeth — the molars and premolars where most cavities in kids occur.
The back teeth have deep grooves and pits that are nearly impossible to clean completely with a toothbrush. Food and bacteria get trapped in these tiny crevices and cause decay over time — even in kids who brush and floss regularly.
Sealants act like a shield. They fill in those grooves and create a smooth surface that’s easy to clean and hard for bacteria to penetrate. It’s one of the most effective preventive treatments available for children.
Why Parents Choose Sealants
Sealants can prevent up to 80% of cavities in the back teeth, where 9 out of 10 cavities in children occur.
No drilling, no needles, no discomfort. The whole process takes just a few minutes per tooth.
Preventing a cavity now is far less expensive than filling one later. Most insurance plans and Medicaid cover sealants.
Sealants can last up to 10 years with regular dental checkups. Dr. O checks them at every visit.
What to Expect — The Sealant Process
The entire procedure is quick, gentle, and completely painless. Most kids are surprised by how easy it is.
Teeth Are Cleaned
Dr. O starts by thoroughly cleaning the teeth that will receive sealants, removing any plaque or debris from the grooves.
Teeth Are Dried & Prepared
Each tooth is dried and a mild gel is applied briefly to help the sealant bond properly. This is rinsed off and the tooth is dried again.
Sealant Is Applied
The liquid sealant is painted onto the tooth’s chewing surface, flowing into all the grooves and pits.
Sealant Is Hardened
A small curing light hardens the sealant in just a few seconds. Your child can eat and drink normally right away.
Frequently Asked Questions
Yes. Dental sealants have been used safely for decades and are recommended by the American Dental Association, the American Academy of Pediatric Dentistry, and the CDC. They are made from a safe resin material and contain only trace amounts of BPA — far less than what children are exposed to in everyday items like food containers or receipts. The protective benefit far outweighs any concern.
The best time to apply sealants is shortly after the permanent molars come in — typically around ages 6 and 12. The first set of permanent molars usually appears around age 6, and the second set around age 12. Dr. O will let you know when your child’s teeth are ready during their regular checkup.
Most dental insurance plans cover sealants for children, usually up to age 14. Medicaid also covers dental sealants for eligible children. Our team will verify your child’s coverage before the appointment so there are no surprises. Call us at (703) 634-9450 with any questions about coverage.
With proper care, sealants can last up to 10 years. Dr. O checks the condition of your child’s sealants at every regular visit and will reapply them if any chipping or wear is detected.
No — sealants protect the chewing surfaces of back teeth, but they don’t cover the sides or spaces between teeth. Regular brushing, flossing, and dental checkups are still essential. Think of sealants as an added layer of protection, not a replacement for good oral hygiene.
Sealants are a preventive treatment and work best on healthy teeth before decay starts. If a small cavity is detected, Dr. O will discuss the best treatment option. In some cases, a sealant may still be appropriate for early-stage decay — he will advise you on what’s best for your child specifically.
