The prime minister told MPs it was down to moderate Muslims to stand up to extremism and tell those with "grievances" against the West they were wrong.
Appearing before the Commons liaison committee of senior MPs, he said he disagreed that ministers were not trying to work with the Muslim community.
Mr Blair told MPs: "If we want to defeat the extremism, we have got to defeat its ideas and we have got to address the completely false sense of grievance against the West.
"In the end, government itself cannot go and root out the extremism in these communities.
"I am probably not the person to go into the Muslim community... It's better that we mobilise the Islamic community itself to do this."
He said there was a "clear and active" threat of further attacks but stressed the "overwhelming majority of Muslims utterly abhor this extremism and are completely on the same side as everybody else in wanting to defeat it".
