2 reasons: One reason is there's only 2 cell layers between tooth an sinus. If sinus still inflamed, teeth may be sensitive until sinus infection is completely cured. Second reason, you may have coincidental but unrelated sinus infection and tooth infection. Call your dentist for examination.

It can: Sinus infections can be very stubborn to resolve. Some can take months. In addition, the position of the upper back teeth can also cause a sinus infection to persist if a tooth is infected (in some cases). It is possible that your sensitivity is originating in the sinus, the tooth, or both. A thorough examination would be necessary to narrow it down.

Yes: Antibiotics does not cure the problem. Make sure the tooth infection is over.
