    Actually, the brain doesn't regenerate either. When someone has brain damage, if they are able to recover in some way it's because another part of the brain takes over that function. The damaged part never regenerates.

    There are literally SO MANY body parts that can't heal as explained by so many in the comments here.
    Here's another example: your spinal discs. Once they rupture, you either deal with permanent back pain and loss of mobility or get surgery to remove it entirely so you stop leaking all over your central nerves (massively painful) and still deal with permanent back pain and loss of mobility.

    • Mika
      Mika 3 months ago +1

      That's actually untrue! In some cases, discs cannot be repaired, but in most cases they actually can heal and the nucleus (gel-like substance inside the disc) can be reabsorbed. It depends on many factors.

      False!!! This is absolutely false. 66% of disc herniations and 98% of disc sequestrations heal spontaneously within 6-12 months! Happy to cite research, this is amazing stuff.

    • Daniel Song
      Daniel Song 2 months ago +1

      Bruh "herniations" is so wide and vague. There are slipped, ruptured, bulging, etc types of herniations. If you guys seriously think a disc that was fully ruptured can be healed, try again. The pain fades over time, but it never goes back to original condition like magic

    • Shapeshift Wellness
      Shapeshift Wellness 2 months ago +1

      @Daniel Song Respectfully, you obviously have no medical training. I’m a doctor and low back pain is my specialty. A “slipped” disc is not even a real thing. For the record, the types of disc injuries include but are not limited to: annular tears, bulges, herniations, extrusions, protrusions, and sequestrations. Now for the research; please read this peer reviewed article showing that 66% of disc herniations resorb spontaneously given time: pubmed.ncbi.nlm.nih.gov/28072796/
      I can share tons of other papers.

      @Aureus From my understanding and from what I have read lungs can't heal like the damage from smoking won't heal or if you are caught in a fire and inhale heated smoke and all that it won't heal to 100% or close to it will be damaged forever. And with heal I mean like the liver that can be abused like hell and basically heal to 100%. But if they mean heal as in it can do something to better than teeth sounds right.

      They do have a limited regenerability, through the presence of the satellite cells. They can divide to become more satellite cells and then differentiate into new striated muscle cells.
      Although as mentioned, they tend to regenerate via hypertrophy rather than hyperplasia.

    • Nerd

      @Sravan S well all of these can “heal” through fibrosis and hypertrophy (for skelly and cardiac). I’m operating under the idea that healing is regenerative- not compensatory.

    I was told by my dentist that your teeth can actually heal themselves on a very slow/long-term level. Obviously not chips (that's like lobbing a finger off). But on a microscopic level your teeth can get better over time in terms of enamel, roots etc. Just not once you get damage past a certain point. At least not in an amount of time that you'd be willing to wait for. But basically he said that your teeth can heal/improve in health over time in a really clean environment. I haven't looked further into it, but I did think this was super interesting.

      I dont think there's a singular gene linked to tooth development. Most likely it's a set of loci that are expressed to promote bone growth of the jaw since you are born with your baby and adult teeth built in. Even if you could somehow cause osteogenesis, where would they be? You don't have any free space for them to develop in.

    I’ve had a chipped tooth when I was a kid, and it sealed itself. You can definitely heal your teeth. It just isn’t acknowledged by the dental industry, likely because there isn’t a medically recognized way to produce high efficacy healing. It is possible, though. People have done it.

      Minute damage to teeth can be "remineralized", which is definitely acknowledged by the dental industry.
      But the amount of damage that it can happen with is miniscule and it technically isn't the tooth "healing itself" so much as the minerals in your mouth just... depositing over time.

    Your scaphoid is a bone in your wrist that will also not heal itself. It has very little blood supply(I believe only one major source) causing fragments that have broken off to die (since they have no blood). The only way to fix the fracture is with emergency surgery.

      Actually scaphoid has two arteries supplying it. They can either enter from the same side or from different sides.
      If the arteries enter from same side then during the fracture the whole supply to the bone gets cut off and it won't heal but if it has supply from different sides then it will heal

    I know they say they heal over time. But I have yet to see anyone with an annular tear of a spinal disc heal itself. They end up popping pain pills, doing physical therapy, resting and eventually just say fuq it and live with the pain or have surgery. Some may have pain relief temporarily from the pills, therapy and rest but the pain comes back bcuz the tear can not heal itself. The only way to heal an annular tear is by injecting Fibrin into the disc.

      Tendons and ligaments have very little blood supply, but will eventually heal to some degree. The degree being basically 0, and "healing" meaning retaining some functionality

    This has nothing to do with the skeleton though. Unlike teeth, bones are extremely regenerative. The difference is that teeth aren't actually alive, it's all dead material produced by cells in your gums (very oversimplified). The only way to regenerate teeth is by replacing them ( like sharks and crocodiles do) or by adding new material at the bottom (like rodents do), this would be similar to how your fingernails and hair grow.
    Also other body parts like the central nervous system don't regenerate either, that's why spinal cord injuries are so terrible.

    He was almost right with the ear answer. The hair cells in your inner ear that convert vibration into what your brain perceives as sound also can’t regenerate. Being deaf in one ear has taught me a thing or two about hearing loss.

      Yes exactly, I can confirm this, as after surgery where the nerves have been cut, I've lost sensation in that area, & it hasn't re-connected or re-grown new nerves.

    The tongue doesnt heal back trust me. When i was a kid some things happened leading to me getting broken glass in my mouth and sliced my tongue and went threw to the other side. Truthfully i don't understand how im still living considering i was not only constantly losing blood but i was also drowing in my own blood. True story btw. Fun fact i can put my finger or other objects threw my tongue now😅

    Not the whole teeth tho.
    Teeth has layers to it.
    The one which can be repaired and can not regenerate is the outermost layer of the teeth known as enamel which covers the crown of the tooth.
    The inner layers tho., can heal and regenerate.

      That’s the same as the cutting off arm argument. Every part of the body is damaged slightly heals/repairs. Teeth are the only that don’t there’s no dna or blueprint in you to regenerate them at all.

      "It's a little smaller now but still there." The fact that it wasn't just a gaping wound for the remainder of your life is proof that your tongue did in fact heal itself.
