When a part of the photo is missing, including creases that appear white, scratches and torn sections that are missing, the results depend a lot on which part of the image is gone. If the missing part was background or clothing or flesh without important details, it can be filled in with color from a surrounding area and is often unnoticeable to the naked eye.

If, on the other hand, the missing section includes details like eyes, hands, fine lines like hair, etc. It may be impossible to achieve results that pass unnoticed.

If the picture is important enough and the detail that is there is sufficient you may be willing to go ahead and acheive whatever is possible. This may fall into the realm of "painting" where the artist is guessing what was there and tries to blend colors in so that the missing details are less noticeable. The resulting image is neccessarily different from the original.

Before we proceed, and before you are charged anything, we will let you know if these limitations apply to your image.
