As far as I'm aware it's not naturally possible as the enamel producing cells which are a vital part of the formation of the tooth are not normally active within human adults. Due to this I doubt that it would be possible to regrow a tooth solely through changing your diet.

Some people of certain descent can grow new enamel, but it is extremely rare and they do not grow new teeth, just put down enamel all the time.  I think it is Inuits, maybe.

alright then, thats what they need to study! cause they can grow a tooth back but they have trouble getting the outer layers to grow like the enamel, thanks for the input!

yep i agree, and to me i know there has to be a way to regrow our teeth, i mean why not? professionals say it can't be done, and have been saying it for years, and now this new research comes out proving that it can be done it just needs more research, i have always been one to question, and i always thought this was possible so thats why i ended up searching it, the problem is there isn't a whole lot of information about it, and thats why i wish people would tell me how they think it could be done, like if they were to do it themselves or attempt to, what methods would they use to regrow teeth? i think if enough people start thinking about it, someone will come up with a way.

ok, so i know what every dentist is gonna say, no its impossible, you get one set of adult teeth and thats it! but why is it impossible? many ideas were once thought to be impossible and later proved to be true. i for one believe it can be done, and i have read things online of people saying how they regrew their teeth, or when their adult tooth fell out, a new adult tooth started to grow in its place, etc. i have also read articles about people supposedly regrowing their teeth by changing the type of food they eat to a far more nutritious diet. so do you think its possible to regrow human teeth through nutrition or any other means? look at beavers their teeth regrow their entire life, and i've read about skeletons being found with a second set of adult teeth below the original, but the thing that pisses me off the most about this subject is the lack of information on it, so if you were to attempt to regrow your tooth, or repair an existing one, what would you need to know? and what methods do you think could work? i don't know much about genetics or dna or even to much about what teeth are composed of, but what i've read about it, teeth are similar but not the same as bone, and your body can regrow bone, and considering we are made of materials readily found on this planet, i just don't see why it can't be done, if we are made up of certain minerals, vitamins, and other materials that are all found on earth, why can't we use them to repair our bodies? sorry i know its a lot of questions but i am really interested about this topic and would like to know more, if you have any information on it please let me know, and i don't wanna sound rude but i would like a answer explaining your position on the matter instead of what you have just heard about it or what your opinion on it is, if you say its impossible explain why that is so, if you say it is possible please also explain why, thanks.

Hi Mike

Yes people can get an extra tooth after losing an adult one but its rare and usually the teeth dont come through normally though. In dentistry there are very rare cases in which they have come through normal and the person has an entire set of them.

Its like cutting your finger off. Sometimes (although very rare) the person will fully regrow it.

The teeth usually arent normal because evolution doesnt have much influence once you've had kids so their has been no selective process applied to them as regards passing yourself on.

thanks for the info psychedelic! yeah i've heard about that, but if it can happen in rare cases then that means that adult teeth can be regrown its just a matter of how! any suggestions?

people who can "regrow" their adult teeth usually have what is called supernumary teeth. meaning they were born with extra teeth. im not sure you can wish yourself a new one. hehe. implants are probably the best way to go if you are healthy and dont smoke. the implant itself is placed into the bone (jaw) and it will grow around it making it quite secure. the part that might break down is the cap or crown that is placed on the implant. they look natural and can be matched to your other teeth color.  aqnyways...i work at a dental office and this is all just everyday stuff to me. :yes:

I've said for years that gene therapy will one day allow us to regrow teeth. It is just a matter of time. I'm not going to hold my breath... or stop going to the dentist though. It could still be decades.

I have an implant and it works great. Cost quite a lot, but much better then a bridge or some kind of denture.

This is the first time I've heard of the sonic tooth growing device.

Here at Intel we make processors on 12 inch wafers. And, the individual processors on the wafers are called die. And, I am employed to check these die. That is why I am the DieChecker.

As you start life out (developmentally) you have what is called an enamel organ. Which is formed by a couple cell types; one being ameloblasts. As the tooth grows and eventually erupts from the gum, it tears through the enamel organ, destroying it.

Without the enamel and dentin matrix you cannot grow new teeth as adults. In some other animals, this processes gets conserved into adult hood--In the lineage that spawned us, and the rest of mammals this was lost. The mammals were rather short lived and so it was a better evolutionary trade off, to allow the cells that form the enamel organ to die out than use resources to maintain them throughout life.

No, nutrition has nothing to do with it. It will likely be possible, sometime in the future, to use bioengineering to harvest stem cells and force them to differentiate into cells that give rise to an enamel organ in vitro, and then transplant the organ into the maxilla.

Continuous tooth deposition is different than regrowing a lost tooth. Continuous growth happens at the level of the root, where a few ameloblasts are maintained to deposit enamel. The majority of continuous growth work is done by odontoblasts, which deposit dentin matrix.

Tooth and bone deposition don't work the same. Bones are continuously deposited and reabsorbed through a restructuring process. This is mediated by special cell types called osteoclasts (a kin to macrophages) and osteoblasts. Unfortunately, we don't have an equivalent cell type for restructuring our teeth. As teeth are deposited they are crystalized with a mineral called hydroxyapatite (similar to bone, but only in much greater amounts). This hard mineralization makes teeth very durable and "long lived".  

From an evolutionary standpoint, we are the sum of our selective pressures. Since most teeth will outlast the reproductive age of the organism (at least for hominids and other mammals) then there is little chance that evolution could favor a system to replace and regrow teeth in humans.

supernumary teeth? ok, well do you know if anybody has studied people with this condition? maybe they can find the gene responsible?
i wish i could wish my teeth back LOL  <_<  yeah i guess implants seem like the best option but i haven't actually lost any of my teeth except i got 1 wisdom tooth taken out, and was supposed to get the others removed but i got dropped from insurance! my main problem is when i was a kid, i hated brushing my teeth, and my mom tried to get me to, but over time i think she just gave up, then fast forward to age 13, i was depressed, and ate alot and drank a 12 pack of mountain dew a day, and it wore away my enamel eventually chipping my front tooth and then two others, but i feel like they are getting worse everyday, and at this point veneers looks like my only option. ok well thanks for the info.

gene therapy huh? i guess i'm gonna have to look into that, never heard of it till now, thanks.
its too bad the military doesn't need soldiers with strong new teeth, cause if that were the case, i'm sure this would have been figured out by now, i think the reason it may be taking so long is a lack of funding for the people studying it.

yeah i heard about it a while ago, and if my memory serves i think they said they could use it to regrow the dentin and everything else, but they couldn't figure out how to grow the enamel back yet, but i think this article could hold the key.

ok i see, do you think it would be possible to take that enamel organ, or the enamel it secretes from a growing wisdom tooth, and use it to regenerate another tooth? and when i say regenerate a tooth, i don't mean a whole one, i mean one that is damaged like a chipped tooth or something along the lines of that.

ok that makes sense, but since it was an evolutionary trade off, do you think since we have such a bad diet that ruins our teeth, we may be slowly evolving to keep that enamel organ or have teeth that last even longer?




No, nutrition has nothing to do with it. It will likely be possible, sometime in the future, to use bioengineering to harvest stem cells and force them to differentiate into cells that give rise to an enamel organ in vitro, and then transplant the organ into the maxilla.




ok, thanks for clearing that up, so all that on the web about nutrition is bull?

yeah i didn't mean a whole tooth just regenerating parts of one.

If they can turn a stem cell into just about anything, I don't see how they will NOT be able to create enamel cells eventually. All they will do is stimulate some stim cells, inject them into the region that needs the tooth and bam, in a year you have a new tooth. The theory and technology already exist, it is simply a matter of creating a successful process to use.

Hello mate here is a link i just found on youtube .
Don't know how serious it is though !

Here is a chick that says you can regenerate teeth by using eggshells ..... http://www.naturalne...generation.html

I am in Australia and boy what i would do for a little help with teeth .
