Curtis Granderson Gets Chipped Tooth Fixed Before Game 6, Check Out My Smile!

Before Curtis Granderson steps into the batter's box Friday night ... he needed a visit to the dentist's chair -- 'cause dude JACKED UP his tooth sliding into second base Wednesday!!

You'll remember ... The Grandy Man legged out a double in the 9th inning of the Brewers' Game 5 loss to the Dodgers -- and his helmet whacked him square in the mug on the slide.

Curtis ended up with a fat lip AND a broken front tooth to go along with the L ... and even said afterward the chipped piece got STUCK IN HIS LIP!!!

BUT ... the story has a happy ending -- 'cause Curtis hit up Mykleby & Thao Family Dentistry in Wauwatosa before Friday night's first pitch ... and he's cheesin' like normal now.

The smile might be fleeting, though ... Milwaukee's on the verge of elimination.
