Swelling in the cheek after getting root canal treatment. Is there an infection?

I had a root canal done last Thursday on the last upper left molar. Within the hour, my left cheek swelled up and I had minor pain. The swelling has gone down a bit but still sore and I noticed a small lump on left cheek...this has never happened to me (I had a previous root canal on another molar). Should I contact the endodontist that did the procedure or my dentist? Could this be an infection? I have no fever and only the discomfort of the root canal/cheek

Thanks for posting your query.
The swollen cheek followed with root canal treatment may be due to-
Improper instrumentation methods used.
Breakage of files inserted.
Periapical infection remaining under the tooth.
Infected vital pulp remaining within the pulp canals.
Take complete course of antibiotics.
Warm saline gargle frequently may relieve swelling.
Apply cold packs alternatively.
Please do visit your endodontist and get further treatments and check-ups.
I wish you good health.

Thanks for asking the query,

Swelling in the cheek after Root canal treatment can be due to persistent infection in the roots, excessive instrumentation during the procedure, infected pulp tissue left in the canal.
I would suggest you to visit the Dentist and get the check up done, take an x-ray of the tooth, if there is infection you can go for re-RCT.
Take tab Amoxiclav and tab brufen twice for three days.
Take lukewarm saline gargles, and antiseptic mouthwash rinses twice dialy.

Hope this helps out.

Hello there ,

Thanks for writing your query,

Swelling in the cheeks post root canal treatment suggests incomplete removal of infected pulp tissue in the root canals that leads to spread of infection to the surrounding structures and in turn it leads to formation of abscess or a lump .

i suspect some remnant of the infected pulp tissue has left unexplored during the root canal procedure or there is a missed canal due to which the infection has gone worse and you have developed a periodontal abscess due to spread of infection to the underlying tissues.

This type of periodontal abscess drains in the oral cavity and may lead to nausea and vomiting.

once the abscess is drained the infected tooth needs to be explored again for root canal procedure.

you need to get an x ray done the affected area to confirm the presence of infection, approach a dentist for the treatment.

i hope this helps ,

take care.
