Can cavities cause sinus issues?

I literally just got over this last month! I was treating myself for sinus congestion for weeks, but it was actually an infected upper molar cavity causing it. Got a root canal and my sinus pressure vanished overnight.

Yes, cavities in the upper jaw can sometimes cause sinus discomfort. Please consult your dentist soon, they will be able to help you resolve this easily.

I can only share what happened to me. I had constant sinus pain and congestion on one side of my face, which my dentist later found was caused by an untreated cavity in my back tooth. Once treated, the sinus issue stopped.

Yes, it is medically proven that upper teeth roots can penetrate the sinus cavity. An infection there will directly cause sinus issues. Stop guessing and get an X-ray done at a good dental clinic.

Actually, while researching dental pain, I read that 'maxillary sinusitis of dental origin' is a real thing. It happens when upper tooth cavities infect the sinus floor. Pretty interesting and definitely worth checking with a dentist.

I am not completely sure, but I know that facial pain can feel very connected. Since my PCOS makes me cautious about bodily inflammation, I would suggest getting a dentist's opinion to see if the cavity is affecting your sinuses.

With my diabetes, I have to be very careful because infections can spread quickly to the sinuses. If you have a cavity and sinus issues, don't ignore it. Eat a low-sugar diet and visit your dentist immediately to avoid complications.
