<s>[INST] I had a root canal on tooth number 3 in December. After a round of antibiotics, I still felt discomfort in my right cheek. It gradually spread to my right eye and around to my temple. Could this be a residual result of the root canal that requires another set of antibiotics? [/INST] Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have discomfort in cheek and eye after root can don't worry discomfit can not be due to root canal treatment it can be due to feeling of heaviness or numbness of anesthesia given during treatment.  Wait for at least 24 hours then if still feels uncomfortable then consult dentist again.  Do warm saline gargle two - three times a day.  Hope this will help you. </s>
