As children grow, so do their smiles—and protecting those smiles from cavities is an important part of pediatric dental care. Alongside brushing, flossing, and regular dental visits, dental sealants are a simple and effective way to help keep kids’ teeth healthy.
If you’re curious about what dental sealants are, how they work, and whether your child may benefit from them, we’ve got answers. Here’s everything parents need to know about this easy and preventive treatment.
What Are Dental Sealants?
Dental sealants are thin, protective coatings that are applied to the chewing surfaces of the back teeth—usually the molars and premolars. These teeth have deep grooves and pits that make them especially vulnerable to cavities, even with regular brushing and flossing.
The sealant material flows into these grooves and hardens, creating a smoother surface that’s easier to clean and less likely to trap food particles and bacteria. In short, sealants act as a barrier to help prevent tooth decay.
Why Are Sealants Important?
The majority of cavities in children occur in the back teeth, where it’s harder to clean effectively. According to the Centers for Disease Control and Prevention (CDC), sealants can prevent up to 80% of cavities in molars over two years. That makes them one of the most effective tools we have for cavity prevention.
Here are some key benefits:
- Effective protection: Sealants reduce the risk of decay in molars, where most cavities in school-age children develop.
- Long-lasting results: With proper care, sealants can last several years before needing reapplication.
- Painless and quick: The procedure is simple and non-invasive, making it an easy experience for both kids and parents.
- Cost-saving: Preventing cavities early on can help avoid more complex and costly dental treatment down the road.
When Should Children Get Sealants?
Timing matters when it comes to sealants. We typically recommend applying sealants when a child’s permanent molars first come in— usually between 6 and 12 years of age.
These teeth are especially at risk for decay shortly after they erupt. Applying sealants early offers the best protection during the cavity-prone childhood and adolescent years.
How are Sealants applied?
Applying dental sealants is quick and easy—each tooth takes just a few minutes. After the tooth is cleaned, the sealant is brushed onto the chewing surface and then hardened with a special curing light. The process is simple, completely painless, and doesn’t require any drilling or numbing. Sealants typically last between 2 to 5 years and provide strong protection against cavities. Your pediatric dentist will check them during regular visits to ensure they’re still doing their job.
Do Sealants Replace Fluoride or Brushing?
Not at all—sealants work best as part of a complete oral health routine. While sealants offer protection on the chewing surfaces of back teeth, fluoride helps strengthen enamel throughout the mouth. Brushing twice a day and flossing daily are still essential for removing plaque and food particles between teeth and along the gumline.
Together, brushing, fluoride, and sealants create a powerful combination to help prevent cavities and keep smiles healthy.
How Long Do Sealants Last?
Sealants are durable and can last several years, especially with regular dental checkups and good oral hygiene. Over time, they may wear down or chip, particularly if a child frequently chews on hard foods like ice or candy.
During routine dental visits, your dentist will check the condition of your child’s sealants and recommend reapplication if needed. The good news is that reapplying sealants is just as easy as the first time.
Are Sealants Safe?
Yes, dental sealants are safe and have been widely used in pediatric dentistry for decades. Some parents have questions about BPA, a compound found in many plastics. While some sealant materials may contain trace amounts of BPA, the exposure level is extremely low—well below the amount considered to be a health risk.
According to the American Dental Association and the CDC, the benefits of sealants far outweigh any minimal risk, making them a safe and trusted choice for cavity prevention.
Are Sealants Worth It?
For many families, the answer is yes. Dental sealants are a small investment in your child’s long-term oral health. They’re quick to apply, require no recovery time, and offer years of protection from cavities. In fact, sealants are one of the most effective and widely recommended tools in pediatric dentistry for preventing tooth decay.
