Adriana, you had mentioned pain in the upper teeth. It is not unusual to get pain with the upper teeth when there is a sinus infection. Reason for this is because many times the roots of the bicuspid and molars may get very close to the sinuses and the pressure in that area can cause sensitivity to the teeth. It does not mean that there is any "problem" with the teeth even if it feels like there would be. when the sinus issues clear up, the teeth sensitivity also goes away.
Of course, if you are having tooth pain, it is a good idea to get it cleared with your dentist that there really isn't a problem with the teeth.
