Veterinarians at Assiniboine Park Zoo were hard at work Tuesday, spending more than four hours operating on an 11-month-old polar bear.

Aurora, a female cub found orphaned in Churchill, arrived at the zoo in October with some dental issues.

She underwent dental surgery to fix some broken teeth. Two of her baby teeth and one adult tooth had to be pulled, according to zoo officials.

After four and a half hours, Aurora was given a clean bill of health and returned to the International Polar Bear Conservation Centre in the zoo.

The operating team was led by Dr. Colleen O’Morrow, who has performed dental surgery on a wolverine at the zoo in the past.

Zoo officials said the animal is now recovering.
