On: First 'tooth regrowth' medicine moves toward clinical trials in Japan

Seems like it shouldn't be referred to as a "regrowth" medicine when you're talking about something that didn't grow in the first place.

It’s talking about growing a third set of teeth so it is regrowth

[sigstoat → eikenberry]

some newspaper translator had to figure out how to translate the novel(ish?) phrase 歯生え薬. what do you want? it's not like this is FDA-approved marketing materials for something that's actually available.

[userbinator → sigstoat]

It's not exactly difficult:

    歯 - tooth
    生え - grow
    薬 - medicine

Doesn't say anything about "regrowth" though.

That has a fascinating answer but requires R, no TL;DR from me :)
