The 21-year-old, who is competing for a midfield place with Mesut Ozil, Mikel Arteta, Aaron Ramsey and Mathieu Flamini, has completed three of his last six matches for Arsene Wenger's side.
England require home victories over Montenegro and Poland to be certain of securing top spot in Group H and qualification to the World Cup, and Hodgson maintains Wilshere will play a vital part in both games.

"Just as I guess Arsene, every week, has to decide 'do I put him in the starting line-up or do I play someone else in front of him?'
"He's in an Arsenal team at the moment with competition for places in midfield that's very strong, anyway. But he's an important cog in our midfield thinking."
Hodgson says his usual priority is to manage Wilshere's fitness issues when the midfielder is on international duty and has praised Wenger's handling of the player's injury problems.
"I don't really have a concern," said Hodgson.
"My concern over Jack has always been whether he is actually physically fit to play or whether he's suffering from an injury.
"I've been led to believe that he doesn't suffer from that injury. He missed a lot of football, didn't he? It was a year and a half then he had to have another top-up to the operation this summer.
"For a young man, he's had an awful lot of serious injury problems but the way that Arsene has managed him since will help us."
