If you think dental work on humans is complicated – imagine treating a 300-pound tiger with teeth seven inches long.

Meet Priya, a 14-year-old tiger rescued from a roadside zoo in Colorado. When her new caretakers at Big Cat Rescue noticed that she had a few infected teeth, they called up tiger vet Dr. Justin Boorstein for help.

Dr. Boorstein might look calm during the procedure, but he claims that it’s always stressful to work with big cats. The biggest risk is not knowing how they will react to anesthesia. Even after sedating around 100 big cats, Dr. Boorstein’s uncertainty remains.
