Is it possible for wisdom teeth growing in to cause a sinus infection?

No unless..........: If you have an infected wisdom tooth, it can spread to your sinuses. However, if you do have a sinus infection, i would look elsewhere first as to the cause. See your physician for treatment. See your dentist as well for an evaluation.

NO: No. But upper wisdom teeth can cause pain simulating a sinus infection. Make sure your wisdom teeth are evaluated and treated by an oral surgeon.
