New York Rangers winger Barclay Goodrow is gonna need an emergency trip to the dentist chair this week ... and it's all 'cause he took a puck straight to the mouth during a game Tuesday night.
Goodrow was attempting to chase down the puck during the first period of NY's tilt with the Senators in Ottawa ... when his teammate, K'Andre Miller, accidentally nailed him in the face with a keep-in attempt.
Goodrow immediately crumpled to the ice in pain ... sliding several feet before he stopped and spit out a bloody tooth.
