Actor Matthew Perry is recovering from emergency dental work as he promotes new Tv remake The Odd Couple after undergoing four root canals in two days.

The former Friends star reveals he recently cracked a tooth while snacking on a bowl of mixed nuts during a trip to Las Vegas and had to undergo a series of surgeries.

He says, "I was in Las Vegas and I was shooting crap (sic)... and I bit into a... peanut medley, mixed nut sort of thing, and my tooth broke at the gum line...

"I get rushed to an emergency dentist and this husband and wife team... they kept looking at my teeth X-rays and kept (shaking their heads)...

"On the first day they did one root canal, so I was in the dentist's chair for two hours and 45 minutes, and on the next day, they did three and I was in the dentists' chair for four hours."
