Red Spot On Gum Above Back Tooth Which Is Painful When Burst. History Of Getting Root Canal Treatment For The Same Tooth. Help

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 rct thn 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 sporidex 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 re-rct or extraction.
but re-rct will save ur tooth.thank u for asking,get well soon

Abscess has to be drained completely and curetted well.
