The 360kg animal was fitted with the largest dental crown ever made in a first-of-its-kind procedure at a Minnesota zoo

An Alaskan brown bear at the Lake Superior Zoo in northeastern Minnesota has a gleaming new silver-coloured canine tooth in a first-of-its-kind procedure for a bear.

The 360kg (800-pound) Tundra was put under sedation on Monday and fitted with a new crown – the largest dental crown ever created, according to the zoo.

“He’s got a little glint in his smile now,” zoo marketing manager Caroline Routley said on Wednesday.

The hour-long procedure was done by Dr. Grace Brown, a board-certified veterinary dentist who helped perform a root canal on the same tooth two years ago.
