It turns out I had a huge infection beneath a crown in one of my molars.  I just had the ccrown and tooh removed today.  There was a 6 mm cyst on one root.  In the meantime, I have had a chronically blocked right eustachian tube (same side as the bad tooth).  Could there be any link?
Hello:)Welcome to Chat Doctor. Yes, infection and pain can be radiated towards the ear. You got the tooth removed, and the infection source is removed. You must have a full course of antibiotics prescribed by your dentist. Also, consult your physician regarding this. Ask your dentist if the removed tooth can be replaced for a better chewing ability. Regards.
