Amir the tiger was put to sleep to fix three of his gnashers after he'd gnawed on some bones and broke a canine and two incisors. Ouch!
Staff at Howletts Wild Animal Park, where nine-year-old Amir lives, feared the 20-stone cat would develop a painful infection, so they took him to their on-site hospital, where dentist Dr Peter Kertesz performed a 75-minute procedure to fill his fangs.
The tooth expert was quoted in the Daily Mirror explaining that the upper canine was hardest, saying: "The tooth pulp was exposed and had become infected."
And the fang in question was 9cm-long - six times the length of a human's!
Amir is one of six Sumatran endangered tigers that lives at the park in Canterbury, Kent.
Ben Warren, head of carnivore section, added: "He is a lovely tiger. We knew a filling would be best to prevent deterioration."
We're sure his pearly whites will be back to looking their best in no time!
