EATONVILLE, WASH. – You could call them the “bear” necessities.
Healthy teeth are pretty important when you’re a 423-pound black bear that eats seven pounds of food every day.
So when Northwest Trek Wildlife Park veterinarian Dr. Allison Case saw that Benton, one of the park’s two black bears, had a fracture in an upper canine, she decided it was time for a root canal.
“During his regular physical checkup last month, I had the opportunity to closely examine his upper left canine and the root exposure,” Case said. “It’s a significant tooth, and we want to protect it long-term. The ideal approach was a root canal.”
Case called in Dr. Kevin Stepaniuk, a veterinary dentist, who has performed root canals on a number of other zoo animals, including a tiger and a polar bear at Point Defiance Zoo & Aquarium. Together with veterinary technician Sara Dunleavy, keeper Haley Withers and Stepaniuk’s own team, they assembled early on Friday for the procedure.
Under full anesthetic, Benton stretched out on his hammock bed in the den under warming blankets. First came cleaning and filing the exposed root and pulp area to remove all decay. The team then disinfected the canal, and Stepaniuk sealed the exposed area from the environment.
While the veterinary team worked, Withers took the chance to get a close look at Benton’s fur, claws, paws and body – something you can’t easily do with an awake, active bear. She trimmed Benton’s claws and assessed his wiry black fur.
Eleven years old, Benton arrived at Northwest Trek in 2014 from the Topeka Zoo in Kansas, along with his sister Fern. The bear siblings share a large forested habitat at the wildlife park, splashing in the stream in summer and sleeping out the winter in a den they built themselves a few years ago.
They are two of four bears at Northwest Trek. Grizzly bear cubs Hawthorne and Huckleberry, who came to the wildlife park last summer after they were orphaned in the wild —- live.
