I had a root canal done on #18 3 weeks ago. All is well and the pain and sensitivity is gone. Ever since then I have had my left ear feel full of pressure. Finally went to urgent care and they said I had an ear infection.

The weird part is almost instantly as soon as I got my numbing shots it felt like my ear filled with fluid and felt like this. It comes and goes throughout the day. I called me Endodontists and he insists it’s just coincidence and that the ear infection must be from something else.

Has anyone here heard or experienced something similar? I’m taking antibiotic ear drops and hope that fixes the issue but for some reason I’m worried it’s teeth related and all connected.
