Hello doctor,Please see the full mouth X-ray that I have uploaded and see if everything is all right or if not, what are the recommendations. I had a root canal on two left sides lower teeth two years back, which along with the cap is visible in the X-ray.
Hello, Welcome to Chat Doctor forum. I am sorry to inform you that there seems to be mild to moderate infection near the root of the lower left first molar. It is better to go for systemic as well as some local or topical antibiotic (gel) and see the regression in three to five days. The other options include repeating the root canal treatment or extraction. (Let us not hope this does not happen). Rest of the teeth appear fine in the x-ray, except for some incipient caries, that need to be examined, diagnosed, and treated clinically. I hope it helps you.
