It seems as though every 2 or 3 years, some researchers publish an article and the news picks up on it and goes “Huzzah! We can regrow our teeth now!” and then it goes nowhere and fades into nothingness.
It got me thinking, what *is* stopping us from regrowing teeth? Is it the inability to generate new enamel? Can we not do that outside the body and ‘attach’ it? Or is there an issue with attaching it to the tooth? Cause if we can grow enamel (even though I’m not sure we can), it seems weird to me that we couldn’t just make a mold of a tooth, make enamel over it, shape it right, and then just attach it somehow to the tooth.
What is actually stopping us from doing this? Additionally, how long should it *really* be before we get proper tooth enamel repairs in the average joe?

It’s fairly simple for a dentist to repair enamel, and allegedly, the dentin can heal just fine if you balance the microbiome of the mouth.

But I’ve never had a dentist say these things.
