What Causes Lymph Nodes In Neck, Under Arms After Having Root Canal?

I recently had a root canal on an infected tooth. I am now having issues with sore lymph nodes in my neck mad under both arms. Do you think the infection is still present in my body? I have a temporary crown but is seriously considering just having the tooth extracted to get some relief.

Hello there,

Welcome to HCM,

Lymph node enlargement or lymphadenopathy is seen in any kind of bacterial and viral infections in the body.
It can rarely be associated with a root canal treated tooth.
lymphadenopathy in the neck area can be due to infected tooth but that of under the arms is totally a different issue.
exact diagnosis can be made only after clinical examination and evaluation by taking radiographs.
i would suggest you to get an OPG radiograph done which will help in diagnosis and accordingly treatment can be planned .
consult an oral surgeon and get the examination done.

i hope this helps,
take care.
I find this answer helpful
