“ I am a middle aged woman, and I work in marketing, so I take very good care of my teeth. I do not smoke and drink only once or twice a month, and only a cocktail or two. My problem is, I have noticed a bump on my gum, above my left canine on my upper jaw. What is this from? Can it be oral cancer? The bump is roughly 5-6 millimeters in diameter, and is raised some 3-4 millimeters. What could it be?”
