UFC stud Anthony Smith didn't just lose his fight Wednesday -- he lost his teeth -- spittin' chiclets during his war with Glover Teixiera.
31-year-old Smith started off strong -- but 40-year-old Glover asserted his dominance in the later rounds ... beating up Smith so badly, he was literally knocking out Anthonys teeth.
At one point. you could see Smith trying to grab a tooth off the octagon mat to hand to the referee.
"I couldn’t keep my mouthpiece in place due to the missing tooth,” Smith told ESPN's Ariel Helwani after the fight.
