Questioni have a 3 year old guinea pig. i realized that he has black stuff on his teeth i tried to get it off and it did not come off. is this something that can be treated or not.
AnswerClohey,
You had best take him to a vet and have it looked at. As always recommended when it comes to teeth or mouth of a Guinea Pig it is best to take him to a vet.
All problems with teeth are pretty much treatable. You don't have to worry about it not being treatable.
Though taking him to the vet to have it check out is a good idea, as teeth problems can lead to starvation and death if left unchecked and untreated.
I hope this helps and that everything is alright with your Guinea Pig,
Take care now,
Jules
