Our bones heal naturally when broken, at least to some extent, so why is it not the same with teeth, which are arguably more useful?
Even the tooth regrowing drug developed recently will be first tested on humans with congenitally missing tooth, not those who lost their teeth later in life, at least from what I understand, which means there’s no *re*growing anything.
Will it ever be possible to fully regrow a tooth and have it be just like the one you lost?

Easieriis to explain why bones can heal. They naturally have cells in them that constantly move through the bone breaking it down and replacing it. Teeth do not have such cells so can’t regrow or repair.
As an aside the death of those cells with age is one reason why elderly people break bones easier and take longer to recover
