“For about a week now, I have had constant pain in a teeth with a cavity on it. Painkillers only work for a short time, and then he terrible pain begins anew. My tooth is extremely sensitive to both hot and cold. The glands near my ears are swollen, and yesterday I had a terrible headache. I have an appointment to see a dentist on Thursday, but I am going mad with pain. What can I do? Is this an infection? Thank you: Petra S.
