I have had pain in my lower jaw and one of my lower molars for over one week. I even started getting pain in my jaw, neck, and ear. Then on New Year's Eve, I started feeling really sick. My whole mouth hurt. When I swallowed, it hurt my head. It felt as if something was stuck in my soft palate. Then on New Year's Day, I started blowing and spitting out large clots of blood with green and yellow mixed mucus. I went to my doctor and she said I have a very bad sinus infection. My dentist's office finally opened this past Thursday. I got an emergency appointment. He told me I have an infected molar, but he wants me to wait to see if the Amoxicillin 1000 mg twice daily will help my tooth too.

My question is whether you think my tooth could have caused the sinus infection.

Absolutely yes - Sinus Infections and Dental Oral Health

Yes. Years ago I had a bad tooth that I was waiting to get taken care of and it caused me a sinus infection.

Me too. So sick for many months, with a bronchial cough, couldn't walk up stairs, no antibiotics worked, because of an infection under a crown. Go straight to an oral surgeon, NOT your dentist, for this, despite the higher cost.

And I will make it four, yes of course, tooth infections can cause 100's of other body illness

Thank you for answering my question. I'm going to call my dentist tomorrow so I can get it pulled. I have had bad luck with root canals and ended up having all four upper molars and porcelain crowns pulled. That was way too expensive and I definitely will not do it again.

As did I, I ended up having to have many teeth pulled for various reasons

I agree about never again - all that money spent on root canals and crowns, believing that they lasted forever, and having no idea how much can go wrong. Does any dentist ever warn people?
