A female polar bear living at the Assiniboine Park Zoo in Winnipeg died during a dental procedure while under anesthesia.
The zoo confirmed that nine-year-old polar bear Aurora died on Tuesday, CTV News reported.
“It’s always very sad when we lose animals at the zoo and in this particular case it was even more difficult in the circumstances of her passing,” said Grant Furniss, the zoo’s senior director of zoological operations.
Aurora had recurring dental problems since she was rescued and moved to the petting zoo in 2013. She was found wandering alone around Churchill Airport when she was around a year old.
The zoo believes her teeth were damaged by eating rocks and sticks in an effort to survive without her mother.
According to the zoo, the procedure went well, but as the team prepared to reverse the anesthesia, Aurora went into cardiac arrest.
“Aurora was a much loved bear and she brought joy to hundreds of thousands of people coming in and out of the zoo,” Furniss said.
