I have no tooth ache or swelling but have earache and numbness to left side of face, ear and jaw?

See your dentist: Sounds like the numbness is in the area of the facial nerve. You may have a case of bells palsey or a virus that effects this nerve. See your dentist to rule out a dental cause or see your physician.

Need exam: This may or may not be a dental issue. With numbness occurring, you don't want to wait. Please call a dentist asap who can do an exam, see if it is a dental issue and if not dental refer you to someone who can help you. Good luck and don't wait.

Could be either: Sounds like a possible TMJ issue. Have it checked out by a dentist that knows how to diagnose and treat tmj.

Bell's Palsy: Bell's Palsy, inflammation of the Facial Nerve and/or surrounding tissues. See your General Dentist, General Physician or Urgent Care (not ER), Specialist in Oral Pathology, or a Specialist Neurologist for physical examination and differential diagnosis. For best resolution, seek examination as soon as possible.
