Hi. I have had a red spot on my gum just above one of my back teeth for about a year now and it gives me discomfort now and again, especially if it bursts. I have been to the dentist twice since it first appeared and I will soon be back. I got root canal treatment for it but its still here. Any help would be great thanks
Well, u have periapical infection from carious origin. Generally if the tooth is treated properly by act the there should not be any pain or any discomfort or any red spot above the tooth. The red spot above the tooth with discomfort indicate the presence of sinus tract which generally happen due to active periapical infection. Now u can take some antibiotic like stories AF 750 mg twice daily for 5 days with met 400 mg thrice daily for 3 days.to get relieved .for permanent solution u have to go for reject or extraction. But reject will save your tooth. Thank u for asking, get well soon
