The 27-year-old is still being troubled by the effects of groin and ankle problems which frustrated his start to the campaign.
But Bent, who scored during Villa's 2-0 victory over Wigan on Saturday, insists he is ready for action if called upon by England boss Fabio Capello.
"If I get the opportunity to play then I will," Bent told the Daily Star. "After games I have to ice one or two bits and bobs like my ankles and groins.
"I have to keep on top of my groins, because they are niggly. As a footballer, you want to play in every game you can.
"It has been a frustrating start to the season for me to be honest, but all I can do is try and keep on top of it and I will be fine."
He added: "I did the first groin and got better then did the second one, which was a bit disappointing.
"But you have to get yourself right and I keep working on it every day and hopefully it will be fine."
England, currently top of qualifying Group G by six points, need just one more point to secure a spot in next summer's tournament.
Former Sunderland man Bent is certain Capello's side can finish the job in Montenegro: "I do believe that at Wembley they came to shut up shop and it was a case of attack versus defence.
"But over there, they are going to go for it as well, so there is no reason why it shouldn't be an open game with chances.
"I'm sure we can go over there and get the result everyone wants."
