If it is too deep to hide, would it be possible to get a matching laminate plank and replace that one? Do you have any to spare from the original installation? (always a good idea with flooring and tiling) Would it be possible to swap that plank for one in a less noticeable position? (e.g. such as beneath a piece of furniture or inside a cupboard) A "magic man" or "plastic surgeion" would probably be able to hide it for you, but they don;t come cheap
