If your child's dentist recommends a dental sealant, you may wonder whether it's really necessary. Sealants are a simple preventive treatment designed to protect the grooves and pits on the chewing surfaces of back teeth, where cavities can be harder to prevent with brushing alone.
At Hines Little Smiles, our team of pediatric dentists and hygienists carefully evaluates your child’s individual cavity risk, tooth anatomy, and brushing habits when deciding whether sealants are the right fit. When recommended, the process is quick, doesn't require drilling or numbing, and can often be completed during a regular visit.
If you’d like to learn more about how sealants fit into your child’s preventive care plan, we invite you to continue exploring our helpful articles or speak with our team at your next visit.
A dental sealant is a thin protective material placed over the natural pits and grooves of a tooth. These grooves are common on molars, and some can be difficult for toothbrush bristles to reach.
The sealant fills those areas and hardens to create a smoother surface. This makes it more difficult for food and bacteria to collect in the deepest grooves.
Sealants are most commonly placed on molars and sometimes premolars, depending on the shape of the teeth and your child's individual needs.
Molars have uneven chewing surfaces with grooves that can trap food and bacteria. Children are also still developing the brushing skills needed to thoroughly clean the back of their mouths.
Permanent molars begin coming in around age six, with another set typically arriving around age twelve. Because these teeth need to last for many years, protecting them early can be helpful when their grooves are particularly deep or difficult to clean.
Sealants work as a physical barrier over the grooves of a tooth. By covering those areas, they can help keep food and bacteria from settling into places that are difficult to clean.
They are a preventive treatment, not a replacement for daily oral hygiene. Your child should continue brushing twice a day with fluoride toothpaste and cleaning between the teeth as recommended.
Sealant placement is usually a straightforward process:
There is no drilling or numbing, and the tooth can typically be used normally afterward.
Sealants can last for several years, but they can wear or chip over time because molars handle a lot of chewing.
That's why we check them during regular dental visits. If a sealant becomes worn or damaged, we can determine whether it needs to be repaired or replaced.
Good brushing habits also help protect the tooth around and underneath the sealed area.
Sealants are helpful, but they aren't a complete shield against cavities.
Sealants may be recommended when a child has deep grooves, a higher risk of cavities, or difficulty thoroughly cleaning the back teeth.
We consider factors such as your child's tooth anatomy, dental history, brushing habits, and overall cavity risk before recommending them. Baby molars may also benefit from sealants when their grooves make them more difficult to keep clean.
For children who are nervous about dental treatment, sealants can also be a relatively simple preventive procedure because they don't involve drilling or injections.
No. Sealant placement doesn't require drilling or local anesthetic. Your child may notice the taste of the conditioning material, but the procedure itself shouldn't be painful.
Yes. Sealants protect the surfaces where they're placed, but cavities can still develop elsewhere. Regular brushing, flossing, and dental visits remain important.
Let us know so we can examine the tooth. If needed, we can repair or replace the sealant.
No. They serve different purposes. Fluoride helps strengthen enamel, while sealants provide a physical barrier over the grooves of certain teeth. They can work together as part of a cavity-prevention plan.
Dental sealants are a quick way to add protection to the teeth that can be hardest for children to keep clean. Whether your child would benefit from them depends on their individual teeth and risk for decay.
