Cavities in my kid's back teeth even though they brush
It is frustrating to watch your child brush every night and still hear the word cavity. The reason is usually the shape of the back teeth. Their chewing surfaces have deep grooves that are often narrower than a single toothbrush bristle, so food and bacteria settle where no brush can reach. That is where most cavities in children begin, and it does not mean you or your child did something wrong. A sealant closes those grooves off so there is nothing left to trap food.
Not wanting my child to need a shot or a drill
Placing a sealant needs no numbing and no drilling, which makes it one of the gentlest things your child will have done at the dentist. The tooth is cleaned and dried, a thin liquid is painted into the grooves, and a small light hardens it in seconds. Each tooth takes only a few minutes, and your child can eat normally right after. As with every visit here, each step is named and shown to your child before it happens.
Knowing whether sealants are actually worth it
Sealants matter most on the permanent molars, which usually come in around age 6 and again around age 12, ideally soon after they break through. According to the CDC, sealants prevent about 80 percent of cavities in the back teeth for the first two years, and keep protecting against about half of them for up to four years. Not every tooth needs one. Some back teeth have shallow grooves that clean easily, and a tooth that already has a cavity needs a filling instead. The dentist checks each molar and tells you plainly which would benefit, and you see the teeth on the screen so you know exactly what the recommendation is based on.
Sealants at school versus at the dentist
Ohio has run school-based sealant programs for more than 40 years, but the Ohio Department of Health aims them at schools where at least 40 percent of students qualify for free or reduced-price meals. If your child's school is not one of them, the dentist's chair is where sealants happen. Placing them during a regular cleaning here also means the same team checks them at every six-month visit and catches any that have worn, rather than finding out years later.
How long sealants last
Sealants can last for years with normal chewing, though they do wear down over time and occasionally a piece chips off. That is why they get checked at every cleaning. If one has worn thin, it can usually be patched or replaced, again with no drilling. Your child should still brush and floss as usual, since sealants protect the chewing surfaces of the back teeth but not the tight spaces between them. Fluoride works alongside sealants by strengthening the rest of the tooth surface.
Frequently asked questions
Do sealants hurt?
No. There is no shot, no drilling and no numbing. The tooth is cleaned, a liquid is painted into the grooves, and a light hardens it. For most kids, the hardest part is keeping their mouth open for a few minutes. Your child can eat and drink normally as soon as the visit is over.
At what age should my child get sealants?
Usually as soon as the first permanent molars come in, around age 6, and again when the second molars arrive around age 12. Sealing them early protects the grooves before a cavity has a chance to start. Some baby molars with very deep grooves may benefit too, and the dentist will tell you if your child's do.
What are sealants made of?
Sealants are a thin, tooth-colored or clear resin, similar to the material used in tooth-colored fillings. The American Dental Association considers them safe and notes that any BPA exposure from a sealant is extremely low, lower than what people take in every day from food and the environment. If you have questions about the material, ask at the visit and you will get a straight answer.
Are sealants safe? I have heard about BPA.
Yes. Some sealant materials can release a tiny trace of BPA for a few hours after they are placed, but the amount is far smaller than what people are exposed to every day from food packaging and receipts. The American Dental Association considers sealants safe for children. If you would like to talk it through, ask at the visit and the team will explain the material being used.
Can adults get sealants?
Yes. Sealants are most common for kids, but an adult with deep grooves and no fillings in a back tooth can benefit too. Since the whole family is seen in this office, the dentist can check your own molars at your cleaning and tell you honestly whether a sealant is worth it for you.
What happens if a sealant comes off?
It is not an emergency. The tooth is simply back to the way it was before it was sealed. Mention it at the next visit, or sooner if your child feels a rough edge, and the sealant can be checked and redone without drilling. Sealants are looked at during every cleaning, so a worn one usually gets caught before it matters.
