Hello doctor, I had a tooth extracted, and it resulted in the perforated sinus. I was on antibiotics Amoxicillin for seven days before and three days after the extraction. I took all the medicines on the sixth day I got a bad sinus infection. I went to my primary care doctor she put me on Amoxicillin once again. She told me to go back to the dentist if there is no improvement. I went back to the dentist, and she prescribed Augmentin and advised to go to an oral surgeon, and he confirmed the sinus perforation. He told me it was healing and told me to stay on antibiotics come back in two weeks for follow-up. After six days on Augmentin, I am still having bad headaches in the front by my eye and a lot of sinus pressure. I am taking the Augmentin, Sudafed, Off Brand Flonase, Tylenol, Ibuprofen 800, and Asprin alternating. Should I be taking another type of antibiotics, or do you feel the Augmentin is working?
Hello.  Did you get a CT scan done to see the size of the fistula? It's called an oro-antral fistula. If it is big then it may have to be corrected surgically. Additionally if the infection is not healing one can give a thorough antral wash and wash out the contents of the sinus in an operation theatre under anesthesia which will help in bringing down the load of infection and help the antibiotics act. Since you have taken amoxicillin/augmentin for quite some time, I also feel the antibiotic can be changed into a stronger one with a broader action, say like Levofloxacin and Metronidazole.
