The Canadiens had scored three goals in a 4:23 span midway through the third period to take the lead.
Caufield scored with a one-timer from the left circle to cut it to 4-3 at 8:41, Alexandre Carrier tied it 4-4 with a goal from the inside edge of the right circle at 11:47, and Caufield scored again with a netfront redirection of Dobson’s shot from the left circle, putting Montreal in front 5-4 at 13:04.
The Canadiens also scored three straight times in the third period on Tuesday at the San Jose Sharks to tie the score, but gave up two late goals in the 7-5 loss.
"To battle back in these types of games, it can be hard, especially with how offensively gifted these last two teams were," Hutson said. "It's always a positive thing, and we got better for sure."
Trouba's wrist shot through traffic from the right point 20 seconds into the game was disallowed after a coaches' challenge showed Kreider was offside prior to the goal.
Gauthier quickly got the Ducks back on the board, finishing a rush with a one-timer from the right face-off circle for a 1-0 lead 39 seconds into the game.
It was his sixth goal in a four-game goal streak.
“There's just a lot of young talent in the room," Kreider said. "A lot of guys who have game-breaking skill and do stuff that, honestly, I've never seen before. At any point in time, those guys can break out and score goals.”
