About the cause of gum boil, I got different opinions from two dentists: 1. It is due to deep pocket in tooth 14 and suggest 14 to be pulled. 2. It is due to dead pulp of 15. Tooth 14 and 15 need and tooth 14 need gum surgery to remove the pocket.
I am a bit confused about who was right on the gum boil. I cannot see infection of root of tooth 15 on as in many X-rays. Besides, tooth 15 is still alive. The second dentist said the infection is on the inner of the tooth 15 which cannot be seen from X-ray. But the boil is on tooth 15, so it is hard for me to believe the first dentist also.
Could some one give me some hints on this? Thanks a lot.
