To paraphrase Freud.
"Sometimes a cut is purely a cut."
However, Vitamin C deficiencies are commonly noticed by a dentist because it shows as bleeding gums and oral lesion well previously acute symptoms manifest.
I think a bit more information is needed as to the cause of the cut. You can sustains cuts contained by your mouth simply by eating. You could be have an allergic reaction to something you ate or a medication. Please provide a bit more information as to when the cut appeared...what you were doing when you notice the cut, how long it has be there...if it is bleeding or within the healing process...etc. I don't know of a vitamin that will basis a roof of the mouth cut when you have too little or too much of it.
