It is quite common that patients come into the office with a “tooth ache” on their upper back molars. A good percentage of the time, the pain is actually from a new or long-standing sinus infection. The symptom that many patients talk about is biting pain and general diffused pain with their upper molars and sometimes their bicuspids. Tests in the office can rule out if it is tooth related. With x-rays and clinical tests, we can determine if it is a sinus infection. So, before you have a root canal make sure you determine whether the pain is coming from the tooth and possible nerve death or from a sinus infection causing tooth related pain.
