>You want to look for a vet who is board certified in animal dentistry >and/or oral surgery. That's a very good suggestion. If you simply go to the yellow pages here on Yahoo, and type in your home town and the search keywords "veterinary dentist" - you'll probably come up with something. Ferrets don't really get cavities, but you may be looking at a broken tooth, with a slab fracture showing the pulp cavity. Ferrets get a type of cavity-like lesion underneath the gumline called a resorptive defect, although I've never seen one (although I've never much looked - but I'm going to start). with kindest regards, Bruce Williams, DVM [Posted in FML issue 3738]
