Gignac, who has scored three goals in three games to help Marseille enjoy a perfect start to the season, had not made France squad since the 2010 World Cup.
The 27-year-old, who has played 16 times for France, rediscovered his scoring touch last season with 13 league goals after two dismal campaigns under former Marseille coach Deschamps in which the pair endured a difficult relationship.
"My point is to call players who are efficient and who can bring something to the squad," Deschamps told reporters.
"We had had a troubled relationship in Marseille but then I had to field him and time has gone by. We have talked about this and we don't have anymore problems from this points of view," he added.
France have been not scored in their last four matches and Benzema has not found the net since a friendly against Estonia before the 2012 European Championship.
"Regarding what (Gignac) has achieved with his club and the needs that are ours, he can have a role to play," Deschamps said.
France are second in their qualifying group, one point behind world champions Spain with three matches left.
They host Finland for the final game next month.
