What do you give a 28-stone silverback gorilla with toothache? A wide berth - unless, that is, you are London dentist Peter Kertesz.
Dr Kertesz, 64, who specialises in wildlife dentistry, spent 45 minutes operating on the animal, called Pertinax, to successfully remove a three-inch tooth.
Officials at the Paignton Zoo in Devon, where surgery took place, say Pertinax was "understandably groggy" following the operation, for which he was anaesthetised for two and a half hours.
