Tiger Woods -- My Tooth Is Back!

It's in the hole!!!

Just 8 days after Tiger Woods was spotted in Italy with a missing tooth, the golf superstar surfaced in Phoenix today with a FULL SET of chompers.

Tiger was flashing all of his pearly whites at the Waste Management Phoenix Open at TPC Scottsdale ... with no weird skull mask thing to cover his face.

And get this ... Woods doubled down on his previous story that the front tooth was knocked out by a photographer at his GF's World Cup alpine race in Italy ... saying:

"The photographer changed positions and I got hit. It was an accident. ... And yes there was blood everywhere. All good now."
