Suns forward Torrey Craig will have to make an unexpected visit to the dentist chair today ... and it's all thanks to Giannis Antetokounmpo, who accidentally knocked a tooth out of the dude's mouth during a game on Tuesday night.
The painful moment happened in the third quarter of Milwaukee's tilt with Phoenix ... when Giannis was trying to blow by Craig to get to the basket.
As the Bucks superstar was dribbling, though, he stuck out his elbow -- and inadvertently smashed it into Craig's mouth.
