A dentist who helps rescued animals in his spare time has been nicknamed Bear Drills after a double root canal op on a 39-stone beast.
Norman, a 20-year-old Syrian brown bear, was saved from a former businessman's abandoned zoo by International Animal Rescue.
Found with five others in filthy conditions, his teeth were smashed to pieces after he tried to gnaw his way out of his 12ft by 12ft cage.
