Treatment is to trim the overgrown teeth as they develop.
Scurvy Guinea pigs cannot manufacture their own Vitamin C. Lack of Vitamin C results in scurvy. Scurvy can be fatal. Contact a veterinarian at the first sign of this problem. Contact your veterinarian immediately. If indoors, air conditioning during the heat of summer provides the best prevention.
