Page turn button has lost its reflex and needs to be pushed very hard

by mistake i pushed the button too hard and used it as a support to remove the back case, now it has lost reflex and is slightly out of the frame/rim of the device. by observing the symmetry of the other pair of buttons i know for sure that this one is dipped inwards a little and out of this frame. i have to push it a little harder than usual for it to work. can i fix this manually without replacing the button ? will this cause any problem in the future.
