Have been having severe tooth pain for 6 days. Dr. says is sinus infection affecting teeth. Dentist says tooth has infection around roots, but says roots are in the sinus cavatity. Am taking antibiotics, pain killers (not helping at all!!)Pain has gotten extremely worse. The only thing that stops the excruciating pain is a sip of cold water washed over the teeth. The pain radiates to teeth around it on top and down in the bottom jaw bone. I aslo have an impacted widsom tooth on top beside the tooth that seems to be the source. Gums are so tender can't stand for food to touch them. I am very confused and in severe pain, any ideas as to the cause?
