Hello doctor, I am suffering from cut of left inner cheek and it will happen on last Tuesday. I never eat tobacco and do not smoke ever. One thing I want to tell you that on that place before cut there was redness either rubbing of teeth or I don't know. Today is 4th day of cut. Its pain full when I touched it by tongue or teeth. Is it sign of cancer I worried about it.

Mouth ulcers/ cuts are very common occurrence, caused by Viral and fungal infections, Although painful most of them heal in 4-5 days duration depending on the size & location of ulcer without any medication. For symptomatic relief one can apply lignocaine containing ointments available over the counter. One should look into cause of ulcer if it occurs frequently. Common causes include indigestion, trauma, stress. If they persist for more than 5 days, then please visit your dentist to find out the cause & to receive appropriate treatment.
