Two years ago a pimple appeared on my gums just above my right front tooth (#8). After breaking it, the abcess reappeared after days had passed and has continued to reappear. At times it seemed like the problem had disappeared but has always reappeared. Now, by pressing on the spot with my thumbnail, a small amount of yellowish ooze squeezes out. I usually do this in the morning and once again later in the day. There is no discomfort. Ever. No pain, no sensitive teeth , no loose teeth. No sensitivity to hot or cold . Occaisionally after sqeezing out the abcess there is a small amount of blood. I ve just been to the dentist and the x-ray showed nothing. The dentist isn t sure what this is.
