    Teeth have always kind of struck me as something we could eventually not just replace or regrow and make as good as new, but actually replace with something better.

    Teeth are, by their nature, subject to a lot of wear and tear, corrosive environments, have a lot of nooks and crannies that need to be cleaned regularly, etc.

    How fucking cool would it be to have some sort of cyborg teeth made of some material that won’t wear down, is more corrosion resistant, stronger than your natural teeth, etc? You could use your teeth as a bottle opener with impunity, or do everything else your parents always warned you not to do with your teeth.

    I’m certainly no doctor or material scientist to suggest what the ideal tooth replacement material would be, but imagine having some kind of titanium alloy super teeth that would never wear down, corrode, or get cavities no matter what kind of neglect or abuse you subject them to, and are purposely engineered for easier flossing, may e even more efficient biting and chewing. Sure, the Jaws look isn’t everyone’s aesthetic, but some of us might consider it a worthwhile trade-off.

    In the meantime though, this is damn cool if it pans out.

      The problem there is that the teeth are supported by the jaw bones.

      We’ve had dental implants for the past 2 decades that are pretty indestructible as you describe. The only problem is the jaw bones you drill into aren’t that robust. Especially when you start putting multiple holes in it to hold the teeth. So the jaw bone part of the implant tends to fail after about a decade or two, even when the tooth part of it is still plenty robust.

      Which frankly is the same problem faced by all proposed cybernetic implants/augmentations. The cybernetic part can be as indestructible as you want, but the organics its attached to are comparatively fragile.

        Yeah and those implants are no joke in strength

        Trigger Warning: true story of workplace injury involving a coworker and his teeth.

        It's light on injury descriptions at least

        One of my coworkers a few months ago had a 200lbs roll of aluminum fall on his head. His implant collided with 3 teeth above it and blew those up.

        He’s mostly recovered at this point from the whole ordeal (concussion, smashed fingers, etc.) he’s just waiting on the bone grafts to heal up for the replacement teeth that are going in.

        And yes he got lucky that the roll mostly glanced off of him towards the front. Had he gotten hit straight on top of the head (or it glanced towards the back) he likely would have broken his neck or died.

      Natural teeth attached to the jaw will always be better than any artificial alternative. Moreso now because they can be regrown.

      Soon we’ll be farming volunteer humans for bone marrow stew. Sign up, have several bones removed—femur, tibia, you name it—and cracked open for that sweet juicy marrow. Then a steady supply of bone growing pills to start the process all over again.

      I had some “teething” as my wisdom teeth came in. It’s painful, and causes a fever, but babies have no understanding of why they are in pain, and no way to deal with it. As an adult, it’s not fun, but it’s manageable and much less scary.

      That’s because their teeth are busting through their fleshy gums. Presumably this would be growing out an existing hole.

      Have you had your wisdom teeth grow? I figure this would be the same. With mine it wasn’t a particularly pleasant experience, but it wasn’t too bad either - and if it’s the same with that new treatment, I’d be willing to take the pain over the alternative of staying toothless when I grow old.

      Crying isn’t always about pain. Babies can’t talk and don’t have the capacity to realize what’s going on. A lot of their crying can simply be chalked up to the frustration of not being able to communicate, not necessarily from pain.

        As far as I know, no national health systems cover cosmetic dental work.

        Certainly both in the UK and in Portugal I always had to pay for it from my own pocket.

        Mind you, neither of those countries has anywhere near US prices even for private healthcare.

        No, some people have a complete third set. Some people only have a partial third set, or even have third teeth in just a few positions within the mouth. A dentist who told me about this said it’s a little rare, but not super rare.

        Not really. The research papers mention an interaction between an antibody and a gene that controls tooth growth in both humans and mice. If that gene is supressed, there is no tooth growth.

        However, every tooth you can ever grow, or at least the embryonal tissue for it, is already present at birth. There is no way to get more, and activating this gene would not give you additional tissue to develop into new teeth.

    I could be crazy but I swear I’ve heard this a number of times before. It always seemed wonderful as my teeth tend to self-destruct. But nothing ever seems to come from it.

    It would be nice if we just naturally grew a new set every 10 years or so but people with strong teeth would be quite annoyed at that especially if they had to do alignment.

        That would be amazing… imagine face planting from a stupid stunt and being like no biggie they’ll grow back. Works for kids and we already know from admittedly gross tumors the human body can grow hair and teeth. Just have to get them in the right place.

        Also agree with the other comment to your post… crispr will likely be for the rich. Hell, it probably already is. A cynical view but i don’t sit at that table so who knows.

        It might seem silly to relate the 2 but it’s just a feeling… major applicable innovation seems lacking.
