A "grumpy" 31-stone (200kg) tiger with an infected tooth has been treated by a Mayfair dentist.
Keepers at Noah's Ark Zoo near Bristol noticed their large male tiger, Khan, was "a bit off" and spotted a chip in his five-inch-long (13cm) canine tooth.
Faced with the "dilemma" of dealing with a tiger with toothache, the zoo called in London surgeon and part-time zoo dentist Dr Peter Kertesz.
Following a 45-minute operation, the zoo said Kahn was "visibly happier".
The tiger has the "strongest bite force of any of the big cats", according to the animal park.
