Hi..
Can understand your concern..
As per your complain pain after
root canal treatment can occur if there is persistent underlying infection causing pain and the pain can radiate to ear.
But in case you do not have any
tooth ache related to the root canal treated and crowned teeth and the x ray also does not reveal any signs of abnormality the
sore throat and earache can be due to
throat infection.
In case if you have any doubt about having your symptoms connected to the dental problem you can take a
second opinion from an ENDODONTIST who is a specialist in root canals and can suggest you better after clinical examination and x ray.
You can try warm saline gargles, throat lozenges , antibiotics and Ibuprofen to relieve sore throat and earache and if it is due to throat infection you will get relieved.
Hope your query is solved..
