What causes stinging and burning sensation on gums?
Patient: This week I began feeling a stinging/burning sensation on my gums. The stinging was felt in the area where one of my top right teeth were removed about 9 years. It feels uncomfortable when I eat or drink. I took a picture of the isnide of my mouth and saw 3 black dents in my gums. Anytime I put my tongue on it it stings. I'm worried because I've never seen this before. Doctor: HiThe condition you have mentioned above is probably your back tooth which was infected and was removed. however professional removal of tooth involves in total removal of the tooth aliong with its roots , which was probably not done in your case ,that explains the three black stumps . Infected root stumps may pose problematic causing pain sensation  in the soft tissue around the root  stumps.I advice you to go to an oral physician ,who will take a radiograph of that area ruling out any other infection . the root stumps need to be removed completely hope this will be of some help to you , take care .
