At 15-2, Boston leads the NBA and matched the best start in franchise history through 17 games. The winning streak is the club's fifth-longest, four behind the 2008-09 team that set the franchise mark, AP reported.
Dennis Schroder had 23 points, and Kent Bazemore added 19 for Atlanta.
The Hawks are an Eastern Conference-worst 3-13, but they still had plenty of adrenaline following a 46-point victory over Sacramento – the biggest in franchise history – two nights ago.
The Celtics erased a 16-point deficit to take their first lead on Brown's 3-pointer midway through the third. It marked Boston's fourth win when trailing by at least 16 during the streak.
"We need to put an emphasis on playing with space and getting the ball to the other side of the floor," said Celtics coach Brad Stevens.
"It just stuck too much early on. We were staring at some post-ups that if we got it to the other side, maybe you could take advantage of."
Irving, playing with a protective mask to protect a minor facial fracture, ended the game with a right-handed finger-roll layup, delighting a few thousand Boston fans who were chanting "MVP! MVP!" in the fourth quarter.
In 31 minutes, Irving made 10 of 12 shots, including five 3-pointers, and hit all five of his free throws.
"We don't try to (go down early)," said Irving following Saturday's win.
"Some teams, they go on runs and whether that be us giving up some easy ones or giving up some turnovers or doing things we can correct. When we do correct them, it turns into a different game."
Stephen Curry scored 35 points, Kevin Durant had 27 and defending NBA champion Golden State overcame a 22-point halftime deficit to beat Philadelphia.
''We take everybody's best shot every night but they fight and fortunately we turned it around,'' Warriors coach Steve Kerr said.
''We weren't locked in, we weren't focused in the first half,'' Kerr said. ''It took the embarrassment of being blown off the floor to get us going.''
Joel Embiid scored 21 points and Ben Simmons had 23 points and 12 assists for Philadelphia. The 76ers led 47-28 after one quarter and 74-52 at the half.
But the Warriors erased that large deficit with a furious rally in the third quarter. Curry's 3-pointer got them within one point. He then made a pair of free throws to give Golden State a 90-89 lead.
The two-time NBA MVP hit another 3 and Draymond Green blew past a defender for a dunk to make it 99-89 going into the fourth.
''I was extremely aggressive in the first quarter, just didn't make the shots,'' Curry said.
''We were more calculated in the third quarter.''
The 47 points allowed in the first quarter was Warriors’ most given up in any quarter since Portland had 48 in the fourth quarter of a game on November 14, 1992.
