Dr Kertesz is one of only a few specialist zoo dentists in the world, a sideline to his day job of treating humans at his surgery in London's West End.
His animal career began more than 20 years ago when someone brought in their cat for treatment and he has carried out dental work on exotic species including whales, pandas and elephants.
Zoo curator Will Walker said: "We have had him twice before over the last couple of years to do all our bears and other tigers."
Dr. Kertesz is paid well for his bravery and expertise, as the bill for the two tigers was £4,500. Link -via Arbroath
