My guinea pig Kevin is 5yrs 6months. He has never suffered tooth problems until recently. I noticed one of his top teeth had broken a few weeks back, and it has now grown really thick, crooked and yellow. Kevin has a vet appointment on Wednesday regarding this. He is eating and drinking normally and doesn’t appear to be in any discomfort. However I have no experience with this, has anyone seen anything like this before and what was the outcome? Sorry for the bad photo. Kevin does have 2 skin tags below his nose / on his lip fold, which the vet has previously checked over and confirmed they are just fleshy lesions!
