Yo what if our teeth grew like nails and we have to cut the every once in a while.
Imagine someone not having proper teeth clipping machinery. Would they eventually cut through their heads with how long their teeth are?
For real though imagine accidentally swallowing a tooth you clipped.
Foxes having huge teeth would be weird right, like a little red dog looking boy scrapping everything in their path, all the dirt collecting on their teeth, other animals too
Penguins, I think the have teeth, but they would have some gnarly chompers living up there (or down there idk)
Octopuses too, I think I would work better with squids but imagine their sharp teeth ripping them up inside
Really the possibilities are endless but,
Nothing I said is as disgusting as the first letters of each line.
