[|Human|] I have some inflammation on my lower front gum , the teeth above the area has a bridge,Ive had oral surgery there ,root canal ect. That was 30 years ago. I floss under the bridge,have my teeth cleaned regularly. Yesterday it looked like a blister was forming now it looks like its gone . It is sore when I press on it
[|AI|]  Thanks for using Chat Doctor. Read your query. Infection or inflammation in any of the tooth under the bridge could have caused the abscess in the region mentioned. Reinfection of the root canal teeth could be the possible reason. I would advise you to visit your endodontist and have a radiograph done to evaluate the status of the treated teeth. If infected you can carry on the re-treatment based on the condition of the teeth. Do salt water gargling. Antibiotic may be required based on the infection. Hope this was useful. Thanks and regards.
