This means the science is over a year old. Where’s the widespread use?
I'm trying to figure out how the science could possibly work, as teeth don't grow once they've finished, nor do they regenerate once damaged. They aren't like bones, surrounded by a living sheath to feed them with materials. They aren't shed but once in a lifetime (usually), and don't replenish their materials. So, tell me, how can they "regenerate" something more rapidly, that doesn't regenerate in the first place?
