Just like the title says. I visited vet a few months ago and he said it may take a little longer for tooth to grow but nothing chamged since then. Upper teeth are starting to become kinda sharp, one is longer than the other and i'm worried because as i know, guinea pigs teeth are growing their whole life, right? I have got two piggies, the one without tooth is about 5 years old, he's friendly, doesn't seem to be in pain or anything. Can this be caused by his age, or something else? I'm sorry for grammar mistakes, english is not my native language :<
