Celtics guard Derrick White left in the first half of Boston’s matchup with Philadelphia on Thursday night with a dental injury that was reminiscent of the one he suffered last year in the NBA Finals.

White knew part of the reason why: he had been pushing off going to the dentist’s office. After the Celtics blew out the 76ers, the starting guard explained what exactly went down that necessitated him leaving the game briefly.

Kelly Oubre Jr. led the way for the Sixers with 27 points, while Justin Edwards 14 in his return from a sprained ankle. Tyrese Maxey and Paul George both missed Thursday's game with ailments.

Sixth Man of the Year favorite Payton Pritchard torched the Sixers back on Feb. 20, draining eight threes in a 28-point performance. He again produced plenty Thursday, tallying 19 points and six assists. Pritchard’s third triple extended Boston’s lead to 63-43 late in the second quarter.

The Sixers traveled to Boston to face the defending champions, who were short-handed on the second night of a back-to-back. With Jayson Tatum, Derrick White and Payton Pritchard available, the Celtics had more than enough to easily handle a Sixers team missing Tyrese Maxey (back) and Paul George (groin) on top of Joel Embiid and many other critical pieces.

Jayson Tatum sleep-walked to 35 points as the short-handed Sixers rolled over for the short-handed Boston Celtics.

The Celtics were already without five rotation players against the 76ers on Wednesday, then one of their starters had to head to the locker room. C’s guard Derrick White looked like he lost a tooth after getting hit in the face by the 76ers' Kelly Oubre Jr.
