You’ve probably heard the word “sealant” at your child’s dental visit. Maybe the hygienist mentioned it, or you saw a permission form. But what exactly are they, and does your child really need them? Dental sealants are one of the most effective ways to prevent cavities in kids. And they are absolutely worth the initial cost.
What Are Dental Sealants?
Sealants are thin, protective coatings painted onto the chewing surfaces of back teeth. They’re made from a plastic-like material that bonds directly to the tooth. Once applied, they create a barrier that keeps food and bacteria out of the deep grooves.
Those grooves are called pits and fissures. They’re perfect hiding spots for cavity-causing bacteria. Even good brushing can miss them because the bristles can’t reach all the way down. Sealants solve that problem by sealing the grooves off.
Why Kids Need Them
Molars are the teeth most likely to get cavities. They appear around age 6, and those first permanent molars have deep grooves that easily trap food. Kids don’t always brush perfectly, and let’s be honest, most adults don’t either.
The CDC reports that sealants can prevent up to 80 percent of cavities in the first few years after placement. That’s a huge win for something so simple. Children ages 6 to 14 benefit most, when permanent molars are coming in.
What About Baby Teeth?
Some parents wonder if sealants are worth it on teeth that will eventually fall out. The answer is yes, in certain cases. Baby teeth hold space for permanent teeth and help with chewing and speech.
If a baby tooth has deep grooves and your child is cavity-prone, sealants can prevent decay from spreading or causing pain. Dr. Lutz and Dr. Shulman will recommend sealants only where they make sense.
The Sealant Process
Putting on sealants is quick and painless. No drilling or numbing is needed. We clean and dry the tooth, then apply a special gel to roughen the surface so the sealant sticks.
Dr. Lutz or Dr. Shulman paints on the sealant, hardens it with a special light, and that’s it. Each tooth takes just a few minutes. Most kids tolerate it easily, and many don’t even realize anything happened.
How Long Do Sealants Last?
Sealants can last up to 10 years with proper care. They do wear down over time, so our team will check them at each visit. If a sealant chips or wears thin, we can touch it up or reapply it.
Good oral hygiene helps them last longer. Brushing twice a day, flossing, and avoiding hard candies or ice will protect both the sealant and the tooth underneath.
Are There Any Downsides?
Sealants are safe and well-studied. Some parents worry about BPA, but the amount in dental sealants is minimal, and major health organizations consider it safe. The benefits far outweigh any theoretical risk.
Sealants don’t replace fluoride or good brushing habits. They protect the chewing surfaces of teeth, but they don’t cover the sides. Flossing between teeth is still essential.
