I wonder how teeth regrowth would work? Our adult teeth don't "push out" like it seems, but our body "grows out and around" the adult teeth formed from early age (maybe even birth? I'm no expert). You can look up pictures of baby skulls where the adult teeth are visible deep in the bone; a baby's adult teeth are formed already, and located in the bone around the lower nose area, some almost on the side of the nose; the baby will grow into them.

- NetBeck 3y agoFrom what I found on teeth development: >The first stage begins in the fetus at about 6 weeks of age. This is when the basic substance of the tooth forms. >Next, the hard tissue that surrounds the teeth is formed, around 3 to 4 months of gestation.[0] [0] https://www.hopkinsmedicine.org/health/wellness-and-prevention/anatomy-and-development-of-the-mouth-and-teeth https://www.hopkinsmedicine.org/health/wellness-and-preventi...
- taurusnoises 3y agoThank you for ruining my mind with this imagery.

- firecall 3y agoIt's weird isn't it! The reverse of how we think it works from external observation alone. It's totally normal to think they grow like nails, but only twice.
