A controversial 52nd-minute Dagenham penalty from Medy Elito was cancelled out by an 89th-minute equaliser from Hughes.
Bentley could not hide his delight with the way his side fought back.
He said: "We knew coming into the game that they were coming off the back of a good win in midweek, they've got loads of legs and are full of youthful enthusiasm.
"I rate them, I think they're an honest side, and I've got a lot of time for the manager.
"He's a good lad and he gets them going, so we knew coming here that it was going to be a tough game.
"I don't think there was much football played, it was quite windy, on a bone-hard pitch, so it was hard to play football.
"But I think both sets of players had a go. It's been a difficult week, the games are coming thick and fast, but I have to say I think it was a poor decision for the penalty which nearly cost us the game, but thankfully it didn't."
Luke Norris' shot was adjudged to have been blocked by Chris McCready's hand, although there was little the defender could have done to get out of the way.
Elito coolly dispatched the resulting spot kick into the bottom right of Barry Roche's goal.
As Dagenham looked to close out the match, Morecambe captain Hughes rescued a point for the Lancashire side with a composed finish from a tight angle in the last minute.
