A female polar bear living at Assiniboine Park Zoo in Winnipeg has died during a dental procedure while under anesthesia. According to the zoo, Aurora experienced recurring dental issues since she was rescued and transferred to the zoo as a cub in 2013. She was initially found wandering around the Churchill Airport alone when she was about a year old. The zoo said it believes her teeth were damaged from eating rocks and sticks in an attempt to survive without her mother.
