Adult Tooth Coming in Behind Baby Tooth

Hi, posted a question not too long ago about my daughter having a loose tooth. She's only 4 and 1/2. After she brushes her teeth, I always brush them as well to make sure we get everything. Yesterday, noticed that her permanent tooth is coming in behind her baby tooth. Just wondering if any of you have had this happen with your child and what happened? Did the baby tooth fall out by itself or have to be pulled? My mom passed away so am unable to ask these questions and my dad doesn't remember. Waiting for a call back from dentist office to see what they say but just curious in the mean time. Thanks.

What can I do next?

It happened to me when I was 5. I had 3 adult teeth coming in behind my baby teeth. Because only one tooth was loose at the time they pulled 4 of my baby teeth. If her tooth is loose already I would think they would leave it alone!

My son was 6 and his two bottom middle adult teeth had grown up behind his baby ones and were almost as tall as his baby ones! His baby teeth were just not getting wiggly, no matter how much we played with them. The dentist had been watching them for a while and decided it was time to pull them. Within weeks of having them both pulled his adult teeth had moved forward into place.

My daughter had this happen with several of her teeth, and yes, we chose to have the baby teeth pulled because it was causing her adult teeth to grow in very crooked.

My teeth started doing that. I'm not sure if that's the norm, or if my baby teeth were just stubborn, but I had to have 6 of mine pulled when the adult teeth came in behind them.

If the baby tooth is not lose yet you need to get her into the dentist. If it's coming in behind it it wont have any room to come in at the right spot. My son had that happen he was older but the dentist said if we didn't pull it we would have issues.

You might prepare for possible braces. Maybe not. One of our kids had that and then the permanent ones crowded and he had two rows with one behind so it had to be pulled for braces. They look nice now. Maybe it will work out for you though. Hope so.

I wasn't 4 1/2, but I had an adult come in behind my kid's tooth adn it actually fused together and I had to have the dentist remove the baby tooth. If you can tell the aduklt tooth is coming in, she shoudl probably work on losing the tooth--and maybe check witht he dentist to see whether it's a concerns she's losing teeth a bit early.

My son had this happen with at least the first 2 teeth he lost. The adult teeth basically pushed the baby teeth out. I did end up pulling those first 2 teeth because they were extremely loose and the roots just would not let go. He lost his first tooth the week he turned 5.

Yes, it's happened. My daughter just lost her two front bottom teeth, her adult ones came up before the little ones were out. I pulled the first, but not after she had wiggled it so much that it was only attached by a "thread". The second she managed to get to fall out on her own. The big ones seem to be moving into their proper place now.

Talk to your little one see if you can't get her to play with it on her own to get to come out.

My daughter is 5, rounding the corner to 6. :)

My oldest has had every adult except one come in before the baby tooth came out. All of his baby teeth have come out on their own. I think we're up to 8 teeth so far, 7 of which the adult tooth came in first.
His dentist said none of them needed to be pulled, they were all fine and would come out on their own.
My second son isn't having the same issue. He's a toothless Jack-o-lantern LOL His are falling out without the same work his brother's did. It's a lot harder work to get the baby tooth out but they all came out. His teeth are fine, they all moved to where they belong.

Totally normal and very common. Google "shark teeth."
You'll be amazed at how those permanent teeth move forward as soon as the baby teeth are out.
No worries. (It's more serious if it's on top--fairly rare though.)

This has happened to both of my sons. My ten year old has so far had to have 9 teeth pulled by the dentist, and only one had fallen out on its own. My dentist recommends instead of trying to wiggle the loose tooth with the adult tooth behind it, push down on the loose tooth. Anyway, his really didn't want to come out. They are making him an appliance to wear to straighten the teeth out, since they are now crooked. My seven year old is going the same way, and has so far had 2 teeth pulled, and 2 have come out on their own. Niether had their first loose tooth until the age of six.

answers from Boise on

Her body is doing exactly wht it is suppose to do.

Baby teeth normally don't have roots like adult teeth, they have a small 'hook' root on one side. They fall out because the big teeth come in behind them and push them out. baby teeth act as a placement guide for adult teeth. They should not be pulled out prematurely or the other teeth get more loose and move in and then the adult tooth doenst have room to come in. Just let them fall out on thier own. If they are mostly out and hanging out by just the root on one side, it is ok to gently help them out.

I'd have the dentist remove the tooth. Then it will move into the space faster than waiting for the baby tooth to come out.

Sometimes those baby teeth can be just plain stubborn!! (Like a watched pot never boils, something like that!)

My daughter lost all 4 top and all 4 bottom by the time she was 4 1/3. It is perfectly normal for her permanent teeth to be coming in. I think you need to get her to a pediatric dentist for a check up and to get her teeth corrected.

I don't think it's totally uncommon. I'm sorry that I don't really know the answer. I guess it does depend on where the tooth is.
Good luck.

This happened to me several times when I was little, and the dentist had to remove the baby tooth. The adult tooth wasn't aligned directly under the baby tooth to push it out. I don't recall it ever hurting (although I was always a bit scared about it), and the dentist always put the tooth into a little box or something for the tooth fairy. I didn't have to have braces, so it doesn't necessarily mean that her adult teeth will be out of place. It's just one of those things that happens :-)

It happened to me. Added to it was an issue that my jaws were smaller than what was needed to accommodate all 16 teeth up and down each. The dentist did what was then known as serial correction for me.
I had nearly 11 milk-teeth extractions, and 4 permanent teeth extractions done by the time they said it was all OK now. I only have 28 teeth! :)

Yes. It happened to my daughter, several times. Some did fall out on their own (well, she wiggled and pulled them out, lol) but one did not, turned black, was still intact and we took her to the dentist to have it pulled.

I was very worried, but our dentist said not to. It isn't uncommon and usually isn't any big deal.
At this point (daughter is 11) we are still waiting on some of her baby teeth to come out. Just had 4 of them pulled last week, b/c we took her in to the orthodontist for a "look see" and she had 4 permanent teeth coming up angled towards the roots of permanent teeth she already has, and they are doing NOTHING to resorb her baby teeth that they SHOULD be coming up underneath.
Pulled the baby ones, to hopefully let the perm ones come up in the open slot, instead of impacting the roots of the 'next door' permanent ones.
This is not something that always happens, by any means. But as a parent, my recommendation would be, when your daughter is a bit older, and if this happen with other teeth (the shark teeth issue), that you take her to an orthodontist for xrays to see if things look ok. Not to scare you! We still are not sure what will happen long term with our daughter yet, but there isn't anything we could have done/would have done differently up until she was about 9 years old. So at 4 1/2, you are good!
No worries. Just keep an eye on it, and encourage her to wiggle the one that "should" be falling out. And get the Tooth Fairy ready...

ETA: Wanted to also point out that the baby tooth doesn't just get pushed out by the permanent one. The permanent one resorbs the root on the baby one, that is why it gets loose. If it comes up behind the baby one, it can't resorb the root, so the baby one takes longer to get loose (if at all). But once the baby one IS gone, the permanent one usually will move forward into the slot, as it is pushed by the tongue constantly. :)
