Did you know that, according to the National Institute of Dental and Craniofacial Research, over 23% of kids between 2 and 5 years and over 50% of those who are 6 to 8 years old have cavities? This incredibly common concern occurs when bacteria in the mouth produce acids that erode their enamel and cause harm.

Fortunately, your pediatric dentist can provide dental sealants to prevent tooth decay from developing. If you’re unsure about what’s involved in this treatment, continue reading to learn about 3 frequently asked questions and their responses!

Question #1: How Are Sealants Different than Fillings?

You are likely already aware that your child’s dentist can provide fillings to treat cavities that have already happened. This procedure involves placing layers of color-matched composite resin to their enamel in layers to rebuild lost or damaged sections, then hardening it in place with an ultraviolet curing light. The resulting repair can last 5 to 10 years if cared for correctly.

Meanwhile, getting dental sealants can prevent your child from developing tooth decay in the first place. This treatment provides a protective barrier that keeps unhealthy germs and plaque from penetrating or injuring their enamel. For this service, your pediatric dentist applies the sealant to the biting surfaces of your kid’s teeth, then applies a curing light to harden the liquid into solid resin.

Question #2: What Are Sealants Made From?

Dental sealants can also be made using composite resin, leading many parents and guardians to question how this service differs from getting tooth-colored fillings. However, most sealants use a type of acrylic that can be customized to match your child’s enamel. In the past, some sealants contained trace amounts of BPA derivatives, but today, more modern, BPR-free formulas are used to safeguard your little one’s smile.

Question #3: How Long Will My Child’s Sealant Last?

This treatment can protect your kid’s grin from bacteria that produce acids and cause decay, but it doesn’t last indefinitely. You can usually expect them to last about 2 to 5 years before they start to wear down, but it depends significantly on your child’s unique circumstances.

For example, treatments placed on molars tend to require replacement sooner because they withstand more pressure from biting and chewing. Thankfully, brushing and flossing twice daily and scheduling routine checkups and cleanings can preserve the results, extending their longevity.

If you’re still unsure if dental sealants are right for your child, the best way to find out is to schedule a consultation with your family’s pediatric dentist!
