Yes it will. It is the difference in distance that the air takes when travelling over the top of the wing versus the path under the wing that causes the lift to be generated! Their are people on this forum that fly planes with damaged wings including serious creases caused by crashes.
The important thing to consider is that ideally the wings should generate equal lift on each side of the plane. This is more important than the amount of lift from a stability point of view.
have fun!
