Dental sealants are often recommended for kids as an extra layer of protection against cavities. But are they worth it? Before you say yes at your next dental appointment, it’s important to understand what sealants do, how they work, and whether they’re truly necessary for your child.
Here’s everything parents need to know to make an informed choice.
What Are Dental Sealants?
Dental sealants are thin, plastic coatings applied to the chewing surfaces of the back teeth (molars and premolars). These are the teeth most vulnerable to cavities because of their deep grooves and pits.
The sealant acts as a barrier, keeping food particles, plaque, and bacteria out of those hard-to-clean areas. They’re typically applied after the permanent molars erupt, usually between ages 6 and 12.
How Are Sealants Applied?
The process is quick, painless, and non-invasive. Here’s what happens:
- The tooth is cleaned and dried.
- A special solution is applied to roughen the surface.
- The tooth is rinsed and dried again.
- The sealant is painted on.
- A curing light hardens it in seconds.
No drilling. No needles. No discomfort. Most appointments take less than 30 minutes.
Do Sealants Prevent Cavities?
Yes, studies show sealants significantly reduce the risk of tooth decay.
- According to the CDC, sealants can prevent 80% of cavities in the back teeth.
- Children without sealants have nearly three times more cavities than those with them.
That’s a big deal considering tooth decay is one of the most common chronic diseases in children.
Are Sealants Safe?
Sealants are considered safe by dental and medical experts, including the Canadian Dental Association
One concern parents sometimes raise is BPA, a chemical used in some plastics. While some sealants contain trace amounts, the levels are extremely low and pose no known health risks. Children are more exposed to BPA from dust, food, and drinks than from dental sealants.
How Long Do Sealants Last?
Sealants can last up to 10 years, but they do need to be checked regularly during dental visits. If one wears down or chips, it can be reapplied.
They’re not a one-and-done solution, but they offer long-term protection during the years when kids are most cavity-prone.
Do All Kids Need Them?
Not always. Sealants are most beneficial for children at higher risk for cavities. This includes kids who:
- Have deep grooves or pits in their teeth
- Have a history of cavities
- Consume a lot of sugary snacks or drinks
- Struggle with brushing or flossing consistently
If your child has flat molars and low cavity risk, a dentist might decide that sealants aren’t necessary.
What Are the Downsides?
Sealants are generally low-risk, but here are a few things to consider:
- Cost: They may not be fully covered by insurance.
- Longevity: They can wear down and need replacement.
- Rare Allergic Reactions: Very uncommon, but possible.
Also, some critics argue sealants may give a false sense of security. They work best alongside daily brushing, flossing, and regular checkups – not in place of them.
What About Baby Teeth?
Sealants are usually applied to permanent teeth, but in some cases, dentists recommend them for baby molars if a child is particularly cavity-prone. The logic is the same: prevention now can save pain, stress, and money later.
Are There Alternatives to Sealants?
There aren’t many direct alternatives that provide the same kind of physical barrier. However, parents can boost their child’s cavity protection by focusing on:
- Good Oral Hygiene: Brushing twice a day with fluoride toothpaste and flossing daily.
- Fluoride Treatments: Offered in dental clinics, these help strengthen enamel.
- Diet Choices: Reducing sugary and sticky foods makes a big impact.
Sealants aren’t a silver bullet, but they are a valuable part of a broader prevention strategy.
What Do Dentists Say?
Most dental professionals recommend sealants for children at moderate to high risk of tooth decay. They’re a simple, cost-effective way to avoid cavities, fillings, and more invasive procedures down the road.
Still, each child is different. The best approach is to ask your dentist directly whether sealants are a good fit based on your child’s oral health, habits, and history.
Final Verdict: Are Sealants Worth It?
In most cases, yes. Sealants are a smart investment in your child’s dental future. They’re quick to apply, safe, and effective at preventing one of the most common childhood health issues.
That said, they’re not mandatory. Parents should weigh the benefits, talk with their dentist, and decide what’s best for their child.
