I have had sinus and dental problems for years. The pain in phenomenal! Sorry to hear you have similar issues. Both my dentist and oral surgeon have taken infections out of my gums, always in the areas that are affected by sinus problems. I stopped having to go to the dentist for sinus trouble when I started using a netti-pot. Daily flushing with saline, and sometimes peroxide or a small drop of cider vinegar works for me. Recently I stopped the regimen for three days, and now am dealing with my first sinus infection in at least seven months. It definitely sounds as if you need to see a doctor and a dentist. Write in and let us know how you are doing.
