I had an abcess a few months ago and got root canal treatment. Now, I am after developing a green-ish spot on my gums. It is just over the tooth i had the abscess in. It is surrounded by a dark purple colour. It is tender to touch and I am very worried it may be another abscess. Do you have any ideas as to what it could be?
Hello, Thanks for consulting ChatDoctorRead your query, as you have undergone root canal treatment now again you feel abscess and sinus opening in tooth this can be due to infection is still present at apical region of tooth causing again pus formation, I will suggest you to consult dentist and go for investigations Iowa X-ray if infection is still present at apex of same tooth then go for RE RCT or removal of tooth. Hope this will help you.
