I woke up two nor three days ago and brushed my teeth. After brushing i expierenced a pain in upper left sid of my top jaw and teeth. i too some advil and the pain got better for brief period. the next day my bottom teeth and jaw expierenced the same pain on the same side. the pain is unbareable. i am wondering if the piain is related to my sinuses because i had a runny nose and slight headache days before the tooth pain. And if it is not a sinus issue what is it. is it possible to have an abcess tooth spread from the top teeth to the bottom?
