In light of all the bad things happening to animals this past week, I thought I'd post something positive...
ANCHORAGE, Alaska (AP) — An Anchorage endodontist performed a root canal on a big tooth in a very big patient — a full-grown Siberian tiger .
Dr. Doug Luiten worked on 300-pound Kunali — measuring nearly 7 feet from backside to nose — Thursday at the Alaska Zoo .
"It's the longest tooth I've ever worked on," Luiten said of more than three-inch (8 centimeter) canine.
The zoo had to order some special instruments to accommodate the longer tooth, and even had to modify those during the root canal.
