Hey doctor! This is the second email I'm sending. The first email was not exactly being specific and I would like you to ignore the other email if possible. Anyways, my problem is that when I floss my teeth, my upper molar gums get really irritated. There is no blood on the floss nor does blood come out when I brush. From what I see, there are no inflammations ,and my gums only hurt when I floss and never else when I'm eating, brushing, etc. And only my upper gums are irritated and in pain. I would like to know what the problem is and how I would go about treating it. I appreciate any help. Thank you.
