Polar bear undergoes root canal at Alaska Zoo

ANCHORAGE, Alaska (InvestigateTV) — Staff at the Alaska Zoo performed a root canal on one of its polar bears after the bear broke a canine tooth.

Kova, 4, shares an enclosure with another polar bear named Cranbeary. The two have toys, treats and a large pool where Kova likes to take her morning swim.

Curator Sam Lavin noticed something was wrong when Kova’s behavior changed.

“Kova is a very interactive and busy bear and she just seemed kind of off. She was pawing at her mouth a little bit,” Lavin said.

Lavin suspected a tooth issue and asked Kova to open her mouth for a closer look.

“We could see that she had broken one of her canines and there’s any number of ways she could have done that,” Lavin said.

An X-ray confirmed the diagnosis. Zoo staff consulted with a veterinary specialist outside Alaska, sent the X-rays and received advice on how to proceed.

“We went with a local doctor to do the work,” Lavin said.

An endodontist who normally operates on humans was part of the large team that performed the root canal on the fully sedated 450-pound bear.

“Everybody knew ahead of time what their role was and what to do and where to be and it was so well planned out and everybody worked so well together,” Lavin said.

The procedure went smoothly.

“She feels so much better,” Lavin said.

The zoo said Kova quickly recovered and is back with her playmate Cranbeary.
