Patient: The patient had all dentures and had a packet of hardened bone or flesh under the dental bed that was not known to be bone. It has been inflamed for about 6 months. There was pain when I pressed it with my hand, and after the pus was squeezed out of the lower jaw 2 months ago in an oral surgery, there were still small bumps of flesh, and it has been inflamed and swollen again for some time. I went to the hospital and had an ultrasound and a film done, and I was told that I had to have surgery. But you have to go to Shenyang, as if there are blood vessels inside the Yingkou side of the surgery can not be, said first in Yingkou hospital baking bake electricity to see the effect. After the pus was squeezed out of the lower jaw 2 months ago at the oral surgery, there have been small bumps, which have been inflamed and swollen for some time. I want to know what exactly is the disease and do I have to have surgery to recover? What can be the result without surgery? Can it recur after surgical removal. Thank you for your reply. Weisheng Wen: Hello! The most likely causes of your gum mass are of two types: inflammation or tumor. If it is inflammation, the causative factors must be found, such as residual roots, osteomyelitis of the jaw bone, etc. The symptoms will be relieved after the cause is removed. The above cases can be diagnosed by taking X-rays. If it is a tumor, pathological examination should be done to determine the nature of the tumor in order to develop a treatment plan.
