Sealants for Kids: When Did Your Dentist Recommend Them?

But now I’m wondering, is it normal to do them this early? Did your kids get sealants right after their molars came in or did you wait a bit?

My kiddo got sealants on her 6-year molars pretty much as soon as they were all the way in. Dentist said it’s actually better to do it early, before any cavities have a chance to start. I didn’t have them as a kid either, so it felt a little weird at first, but I guess it’s just more common now. She didn’t even flinch during the process - honestly, I think she was more annoyed about not being able to eat for a bit after.

If your dentist suggested it, sounds like you’re on track. I know some parents who waited, but then their kids ended up with little cavities that could’ve been avoided. It’s one of those “better safe than sorry” things, I guess. Plus, less drama later on if you can avoid fillings, right?

We did sealants as soon as the molars were fully erupted - our dentist was pretty clear it’s ideal to get them on before any decay sets in. I was a little skeptical at first, but after seeing a couple of my patients’ kids develop cavities in those grooves, I get the logic. Curious if anyone’s dentist mentioned how long sealants typically last? Ours said about five years, but I’ve seen some wear off sooner, especially with kids who grind their teeth.

Ours said about five years, but I’ve seen some wear off sooner, especially with kids who grind their teeth.

Yeah, that’s pretty much what I’ve heard too - five years is the “official” line, but in reality it’s kinda all over the place. My youngest is a champ at teeth grinding (seriously, it sounds like she’s chewing gravel in her sleep), and her sealants started fading after just three years. The dentist said it’s not unusual for them to need a touch-up or even a full redo, especially with little grinders or snack monsters.

Honestly, I’d still do them again, though. Way easier than dealing with a filling later on. It’s wild how deep those grooves are on molars... like, you could lose a raisin in there and never see it again. One thing our dentist mentioned is they’ll just check the sealants at every cleaning and reapply if needed - no big drama.

It’s not a forever fix, but it definitely buys some time before cavities try to sneak in.

We did sealants right after my kid’s 6-year molars showed up, too. Dentist didn’t even hesitate - said it’s easier to do them before any food gunk or decay gets in those grooves. I was a little skeptical since I never had them growing up, but honestly, tech’s changed so much since then.

My son’s lasted about four years before we had to patch a couple spots. He’s pretty rough on his teeth (chews ice, bites pencils... classic). Dentist just checked them at each cleaning and handled it if something was chipped or missing. Never seemed like a huge deal.

Honestly, the cost is way less than even a single filling. No complaints here - if anything, I wish my parents had gotten them for me. I’ve got two fillings in those same molars from back in the day.

- Totally agree on the timing - my dentist was all about catching those 6-year molars early too.

“Dentist didn’t even hesitate - said it’s easier to do them before any food gunk or decay gets in those grooves.”

Honestly, I wish my parents had known about sealants when I was a kid - my molars are basically a silver museum at this point. You nailed it about the grooves; once decay sneaks in, there’s no turning back. My orthodontist actually pointed out that keeping those teeth sealed up early makes braces way less of a hassle later, since you’re not dealing with fillings or extra sensitivity. The popcorn thing made me laugh...my brother lost his to a rogue Skittle. Sealants really do pay for themselves compared to drilling and filling down the line.

Gotta say, I’m not totally sold on sealants being a magic bullet.

Totally get where you’re coming from. My kid had sealants put on last year and one chipped off within months - felt like we were back at square one. It’s a bit frustrating when you’re doing all the right things at home, too. I guess nothing’s really foolproof, just more layers of defense. Sometimes I wonder if it’s more about peace of mind than a real game-changer, especially for kids who already have solid brushing habits.

- Definitely hear you on the frustration. Sealants aren’t bulletproof - more like an extra layer, not a guarantee.

“Sometimes I wonder if it’s more about peace of mind than a real game-changer, especially for kids who already have solid brushing habits.”

“Even with great brushing, those grooves on molars are tough to clean. Sealants cut down risk, especially for kids with deep pits.”

Fully agree here - the grooves are always the trouble spots. My oldest brushes like a champ but still ended up with a cavity in a back molar before we even considered sealants. Dentist said it’s just how those teeth are shaped. Sealants aren’t perfect, but I’d rather have that extra layer than deal with fillings later. It’s more peace of mind for me than anything.

I get why sealants are popular, and I’ve seen them recommended for my grandkids too, but I’m a bit more cautious about jumping straight to them for every kid. Back when my own kids were young - think 80s and early 90s - our dentist was actually a bit on the conservative side. He’d check the molars first, watch for any signs of decay or deep pits, and only suggested sealants if he saw something concerning. His logic was that not all kids have those deep grooves, and sometimes a good brushing routine plus regular checkups did the trick.

I remember one of my sons had what the dentist called “shallow fissures” on his molars. We skipped sealants for him, and he never had a cavity in those teeth. The other had deeper grooves and did get sealants after his first tiny cavity. So, I guess I’ve always thought it depends a lot on the individual tooth shape, not just age or habit.

There’s also the maintenance part people don’t always mention. Sealants can chip or wear down over time, and if you’re not keeping up with regular dental visits, you might not notice if they’ve failed until there’s already decay underneath. I’ve seen that happen with my neighbor’s granddaughter - a sealant cracked, and nobody realized until her next cleaning months later.

I’m not saying sealants aren’t useful - they definitely have their place - but I do think there’s room for a case-by-case approach. Sometimes dentists seem to recommend them across the board these days, maybe out of caution or insurance protocols, but I don’t know that one-size-fits-all makes sense. For some families, especially if insurance doesn’t cover it well, it can add up fast.

Just my two cents from watching several generations go through this... I’d rather see careful evaluation than automatic sealant for every kid. But yeah, those back molar grooves can be sneaky - I don’t envy parents trying to keep up with it all.

That’s really reassuring to read, honestly. I’ve been feeling a bit overwhelmed with all the recommendations for sealants these days - like if you don’t get them, you’re instantly a “bad parent.” Hearing about your experience with your kids and how your dentist took time to actually look at their teeth makes me feel better about asking more questions at our next appointment. I do worry about stuff like maintenance and cost, especially since insurance doesn’t always cover everything. Thanks for sharing - it helps to know it’s okay to take things case by case.

Totally get this. My dentist was all “sealants are great!” but then hit me with the price tag and I nearly spit out my coffee. Honestly, my teeth survived without them as a kid... not sure it’s always a must. Definitely asking more questions next time too.

Yeah, the sticker shock with sealants is real. They do help protect those deep grooves in molars, but honestly, not every kid absolutely needs them. If your child’s brushing game is strong and there’s no history of cavities, sometimes it’s okay to skip or just wait. I always tell folks - ask about risks and benefits for your specific situation... every mouth’s a little different.

I totally get where you’re coming from about the price - my jaw dropped the first time I saw the estimate for sealants on my kid. We ended up doing them because she’s got those super deep grooves, and honestly, she’s not the world’s most diligent brusher (despite my best efforts). But I’ve got friends whose kids skipped them and have been fine, so I think you’re right - it’s not a one-size-fits-all thing.

What helped me decide was asking our dentist to actually show me what he was talking about - he pointed out the grooves and explained her risk. That made it feel more like a real choice, not just a sales pitch. I’m with you: if your kid’s teeth are in good shape and brushing is solid, waiting or skipping isn’t wild. Sometimes dentists just default to “extra protection,” but it’s not always necessary.

Anyway, I’d say trust your gut and ask all the questions you need. Every mouth really is different... and every parent’s budget is too.

I totally relate to the sticker shock - my dentist brought up sealants for my daughter at her last cleaning, and I left feeling like I’d failed some parenting test. I’m still anxious about whether we really need them or if it’s just “extra.” I did ask a million questions, though, and seeing the grooves in her teeth made it feel less abstract. Still, I keep second-guessing myself because my niece never got them and she’s fine so far. It’s hard not to worry you’re missing something important, but hearing others skip or delay helps me breathe a little easier.

I totally get what you mean about the pressure - sometimes I feel like every dental recommendation is just another item on the “good parent” checklist. But honestly, I’ve always wondered if sealants are a must or just a “nice to have.” My dentist suggested them for my son when his molars came in, and I hesitated because, yeah, it’s not cheap, and insurance barely covered any of it.

I ended up waiting a year, partly because of the cost and partly because I wanted to see how his brushing habits played out. He’s not the world’s best brusher, but no cavities yet. I do feel a little guilty sometimes, but then I remember I never had sealants as a kid, and my teeth were fine.

I get that every kid is different, but I don’t think skipping or delaying sealants automatically means you’re doing something wrong. Sometimes it feels like dentists push “extras” pretty hard, and it’s tough to tell what’s really necessary. I just keep reminding myself that being thoughtful about these choices is what matters most.

That checklist feeling is so real - sometimes I swear my dentist is adding “sealants” right after “floss every day” just to mess with my guilt levels. We did end up getting sealants for my daughter when her molars came in, but only after a lot of back-and-forth (and a bit of sticker shock). Honestly, I didn’t have them as a kid either, and I survived. I figure, if your kid’s brushing is decent and you’re keeping an eye on things, waiting or skipping isn’t some parenting fail. There’s always going to be another “must-have,” right?

Honestly, I didn’t have them as a kid either, and I survived.

I get that, and sometimes I wonder if we’re overdoing it with all these “extras.” My own kid’s dentist suggested sealants right when the adult molars popped in, and I hesitated for months. Ended up doing it after a friend’s kid got two cavities in those grooves. Curious if anyone’s dentist actually said it was fine to wait, or is it always an “ASAP” thing?
