Amir needed fillings on three chipped front teeth to prevent any future pain.
He was sedated at Howletts Wild Animal Park in Kent and taken to the on-site hospital for treatment by moggy molar expert Peter Kertesz.
Park vet Jane Hopper said Amir has made a 'purr-fect' recovery, but would keep an eye on him over the next few weeks, the BBC reported.
Experts said it was a difficult procedure because the tooth's root could be six times longer in a tiger than a human.
