Swelling around a previously treated tooth can have various causes, not just re-infection. While re-infection is a common cause of swelling after a root canal treatment (RCT), there are other factors that could contribute to swelling as well. Some possibilities include: Re-infection: Bacteria may have re-entered the treated tooth, causing a new infection. Incomplete Treatment: If the RCT was not fully completed or if some of the infected tissue remained, it can lead to continued or new infection. Complicated Anatomy: Sometimes, the tooth's anatomy can be complex, making it difficult to clean and seal properly during the RCT. Cracked Tooth: A cracked tooth can provide an entry point for bacteria, leading to infection and swelling. Foreign Body Reaction: Sometimes, a small piece of filling material or an instrument used during the RCT can cause an inflammatory reaction. Residual Tissue Irritation: Tissue irritation from the procedure itself can cause temporary swelling. Other Dental Issues: Swelling might also be related to other dental issues in the same area. It's important to consult your dentist or endodontist if you're experiencing swelling after an RCT. They will perform a thorough examination, possibly including an X-ray, to determine the cause of the swelling. If infection is confirmed, appropriate treatment will be recommended, which may involve re-treatment of the root canal, drainage of any abscess, and prescription of antibiotics if necessary. In any case, seeking professional attention promptly is crucial to ensure proper diagnosis and treatment.

Hello Yes if pain and swelling in same tooth thn it is bcz of secondary infection, re rct needed

Please get it checked if it’s the same tooth or some other tooth on that side of face. Could be any upper or lower tooth on the same side. Re infection also could lead to swelling but if RCT was fine by a qualified experienced dentist then Chances are low

Hello. It's usually because of re infection, kindly visit your dental surgeon for physical examination and evaluation

Mostly coz of reinfection for that you have to do re rct

Most probably re infection. Visit a local dentist for physical evaluation, x ray and treatment (as required).

Hi, Visit a your dentist immediately. You could be having re-infection or the adjacent tooth is infected. Get an X-ray taken for the tooth.

Need xray to properly diagnose it.. it can be re infection.. it it’s reinfection re rct will be done

Need an x-ray to complete the diagnosis.

Swelling again on the same side usually indicates a re infection , but you have to be sure if its the same tooth or any other tooth having caries either adjacent to the treated tooth or on the same side.
