The Magpies had to wait until the 84th minute for substitute Shola Ameobi to fire them in front at League Two Morecambe, and the second-round tie was only finally settled in injury time when younger brother Sammy claimed a second.
Bentley said: "At the end of the day, we have given a great account of ourselves.
"I think we were the better side in the first half, we just needed to score when we were on top.
"It could have been a whole different ball game. Their crowd might have got on top of them a little bit, it would have given us that little bit more confidence.
"But we gave a good account of ourselves, we had a right good go and I am proud of all the players for their efforts."
