I was wondering if you could give me some pointers
on what the right-hand-side
gum lump could be. I am thinking that since there is also something
on the left-hand-side, that it may be a lymph node that is acting due to the slow falling-apart of the tooth above it, but I am not sure. My attempts to find out information about lymph nodes in the mouth, and more particularly in the gums, produced no success online.
I am not a smoker or drinker.
