Two weeks ago I got a root canal done on tooth # 13. One week ago I got a temporary crown put on. Starting two days ago I started to have a dull ache pain on my lower jaw and cheekbone. It only happens when I am laying down. The gum looks a little purple. Is that normal? Is having pain one week after getting a temporary crown put in normal? It didn’t hurt the days after I got it, the dull ache has kept me up last night. My next appointment is not until next week. Does everything look okay?
