Why do teeth don't regenerate?

Seems pretty dumb in our biological design to not be able to regenerate such a functional (and also easily breakable) part of our body.

Possible, but it may come with downsides you don't like.

Let me guess, the downside is infinite teeth.

The downside could be something that nobody has imagined yet. That is the problem with change. I'm not against this, but I demand reasonable study. (but not unreasonable levels - vaccines and GMO have been studied enough to conclude they are generally safe despite people yelling more study needed)

Side effects may include dry mouth, diarrhea, attacking swimmers at the beach. Do not take Teethenall if you are allergic to shellfish.

That I could live with.
