Renewal of root canal treatment

[Haroja]

Hello dear dentists, I had root canal treatment in 2016. In 2022, it was decided to renew my root canal treatment because there was a lesion on my tooth root. I had swelling in my gums. 2 years have passed, but the swelling has reoccurred. There is a small hole in my gum with a structure similar to a pimple tip. When I press the swelling, odorless liquid flows out. It doesn't hurt, and frankly it doesn't cause any discomfort. What is the cause of this swelling? I received orthodontic treatment and had 2 teeth extracted in my upper jaw.

The pimple sounds like a draining sinus of an abscess. It sounds like one or both of the root canals might have a recurrent infection. I would advise maybe seeking the opinion of an endodontist. Especially since the root canal has previously been re-done. They can take a 3D-CBCT scan of the tooth to evaluate for any cracks or missed/short filled canals.

It's possible that the swelling and discharge you're experiencing could be due to an infection or abscess around the root of the tooth. This can happen if there's still bacteria present or if the previous root canal treatment wasn't fully successful. It's best to consult with your dentist or endodontist for an evaluation and possible retreatment.

Definitely not a good RCT, so little wonder you're having trouble. At the least the GP is poorly condensed, which also makes me concerned about the quality and sterility of the preparation. You need to see a specialist endodontist for retreatment if possible.
