The back teeth are the hardest surfaces in your child’s mouth to keep clean. Deep grooves and pits on the chewing surfaces of molars trap food and bacteria that even thorough brushing cannot always reach, making those teeth far more vulnerable to cavities. Dental sealants solve this problem by filling those grooves with a thin protective coating, creating a smooth surface that is easy to clean and dramatically less likely to develop decay.
At North Creek Dental Care, children’s dental sealants are a routine part of the preventive care we provide to families throughout Tinley Park and the Southland area. Our pediatric dentist team recommends sealants as one of the most cost-effective and painless investments parents can make in their child’s long-term oral health. Recognized as Southland’s Best Dental Office in both 2024 and 2025, we make every visit comfortable and straightforward for kids of all ages.
What Are Dental Sealants and How Do They Work?
A dental sealant is a thin, plastic-resin coating painted directly onto the chewing surfaces of the back teeth. The material flows into the pits and fissures of the molars, bonding to the enamel and hardening under a curing light. The result is a smooth, sealed surface that blocks food particles and bacteria from settling into the grooves where cavities most commonly begin.
Sealants do not replace brushing and flossing, but they close the gaps that at-home care often misses. According to the CDC, school-age children without sealants are nearly three times more likely to develop cavities in their molars compared to children who have them, and sealants can prevent up to 80% of cavities in the first two years after application.
The Benefits of Sealants for Children
Sealants are quick, painless, and require no drilling or removal of tooth structure. They protect molars during the years children are most susceptible to cavities, can last several years with proper care, and are far more cost-effective than treating decay after it forms. Most PPO insurance plans cover sealants for children as part of preventive benefits.
When Should Children Get Dental Sealants?
The optimal time to apply sealants is as soon as the permanent molars erupt. The first molars typically come in around age six, and the second molars around age twelve. Sealing these teeth shortly after they appear gives children maximum protection during the years when cavities are most likely to develop and when brushing habits may not yet be fully reliable.
In some cases, sealants can also be applied to primary (baby) teeth with especially deep grooves. Our team evaluates each child at their preventive visit and recommends sealants when the timing and clinical picture support them. If your child is in the six-to-twelve age window, now is the ideal time to ask about sealants at their next appointment.
What to Expect During the Sealant Appointment
Applying dental sealants is one of the quickest and most comfortable procedures we offer. The appointment typically takes only a few minutes per tooth and requires no shots, no drilling, and no anesthesia. Our team will clean and dry the tooth, apply a mild etching solution to help the sealant bond, paint the sealant material onto the chewing surface, and then use a curing light to harden it. That’s it.
Your child can eat and drink normally right after the appointment, though we recommend avoiding sticky or hard foods for the first twenty-four hours. Sealants are checked at each routine visit to make sure they remain intact, and any that have worn down can be easily reapplied. Most sealants last several years before needing attention.
Sealants and Fluoride: A Complementary Approach
Sealants and fluoride treatments work together as the two most effective preventive tools in pediatric dentistry. Where fluoride strengthens enamel by remineralizing the tooth surface, sealants provide a physical barrier against the food and bacteria that cause decay. Used together, they significantly reduce a child’s overall cavity risk.
At North Creek Dental Care, we often recommend both treatments as part of a comprehensive preventive visit. Our team can help you understand which combination makes the most sense for your child based on their age, cavity history, and individual risk level. Ask about pediatric fluoride treatments at your child’s next appointment.

Keeping Sealants in Good Shape
Sealants are durable, but a few simple habits help them last longer:
- Avoid chewing on ice, hard candies, or other extremely hard foods
- Steer clear of sticky foods like caramel and gummy candies that can pull at the sealant material
- Brush with a soft-bristled toothbrush twice daily — sealants make brushing easier, not optional
- Keep up with routine dental visits every six months so the team can check sealant integrity
- Ask about fluoride treatments at each visit for added enamel protection
