zoo bear new tooth minnesota.

An Alaska brown bear at the Lake Superior Zoo in northeastern Minnesota has a gleaming new silver-colored canine tooth after a first-of-its-kind procedure. The 800-pound bear named Tundra was put under sedation Monday and fitted with a new titanium alloy crown. The zoo says it’s the largest dental crown ever created. The hour-long procedure was done by Dr. Grace Brown, a board-certified veterinary dentist who helped perform a root canal on the same tooth two years ago. Brown plans to publish a paper on the procedure in the Journal of Veterinary Dentistry later this year.
