A bent car door can be fixed by using a dent puller. It attaches to the dent via a suction cup which allows the dent to be readily popped out.
To fix a car door that is sprung due to a bent or damaged hinge, the best thing to do is replace the hinge. If the hinge is welded and not bolted to the vehicle, the entire door will have to be replaced.

Start by evaluating the frame. If the frame is bent...foreget it. It will never be the same.
It depends on the door and the car. Some use specially designed shims, others slide and are adjusted by loosening the mounting bolts while others still are carefully "bent" as needed to adjust the door.
