Hello sir, as you have gum bleeding you have to go to a dentist and get a thorough scaling and polishing done . Also get a x ray of the root canal treated and check if there is any infection.

Bleeding gums have no concern with infection caused to u. There will bbe because of dirty teeth

Do you have gum infection everywhere or is it only near the rootcanal treated tooth??

U can have chlorhexidine mouthwash..and proper flossing and proxa brushing.. consult your dentist nearby.. to avoid complexity..

Hi If u have gum bleeding or anything like bad breath it should be immediately addressed by doing complete cleaning and polishing . Gargle with plain water after every meal followed by mouthwash at night times . Take a xray over the root canal treated tooth and consult with nearby dentist . Generally yearly once cleaning is mandatory to avoid these kind of gum infection.

Get an X-ray done to check that tooth. The gum swelling may be related to the tooth or the gums in that area. A proper good fitting crown should be done for that tooth if the RCT is ok
