How to treat swelling with pus near an RC-treated tooth?

Question

Hello doctor,

My dentist performed a root canal on one of my upper molars. He assured me it was a minor infection based on the X-ray, but later, he couldn’t manage the infection. A small, hard bump appeared on the gums near the treated tooth.

After a month, he closed the tooth, but it started to swell again. He asked me to take antibiotics and said it was fine. He then filled the tooth, but now the swelling is back. There may be pus inside. What should I do now?

Hello,

Welcome to icliniq.com.

Upon review, these were the findings,

Swelling in the upper right vestibule in relation to the right first molar.
Restoration in relation to the right first molar.

The red color swelling in the gums is probably an abscess due to caries in relation to the right first molar. The filling looks like a temporary restoration. It might also be secondary caries. It is best to check vestibular and tooth tenderness on percussion in relation to the right first molar.

I would suggest access opening in the affected teeth, prescribing antibiotics and painkillers to control infection and pain, and further completing the re-root canal treatment in the right first molar. There will be a good treatment outcome.

Hope I have solved your query. I will be happy to help you further.

Thank you.
