HiI recently had root canal treatment for an abscessed upper front tooth. Have one more treatment to go.Since trouble with my tooth I am experiencing ear ache/pressure in both ears, facial and general discomfort in my gums. I am experiencing nausea intermittently, also an unpleasant bile type taste in my mouth. I also have a blocked left nostril which I  think is sinus related Have you any idea what may be occurring.? Cheers Jennie
Thanks for your query, I have gone through your question, the discomfort in the face and gums could be because of the infection in the tooth. This will be reduced once you complete the course of antibiotics and treatment.....the nausea could be because of the antibiotics and analgesics due to gastric irritation, you can take antacid with antiemetic.....the pain in the ear could not be related to the front tooth infection...consult ENT specialist for that... I hope my answer will help you...take care.
