Is there reason to worry if your jaw aches contantly for a long period of time?
I would suggest making an appointment with your health-care provider to try and determine the etiology of the discomfort. When we experience pain this is a sign from our bodies that something is amiss. Your pain may have a dental cause (etiology), or it could be from other sources, like TMJ for example. Often, females have atypical presentations that are related to common problems. For example, females with AMI, acute myocardial infarction, often complain of jaw or arm pain, not the classic pain of midsternal chest pain or pressure.
Nevertheless, worry is premature, but we should try to figure out what is causing your discomfort. Does anything make the pain worse? Is it constant or does it come and go? These are just a couple of questions your hcp will ask you in trying to figure out the source.
Well, I don't know if worry is the right word to describe it, but concerned enough to seek medical attention is a good idea. Try to determine whether or not it is jaw pain or tooth pain, like an infection at the root level. A dentist or dental surgeon can help you with either, but if the problem is in your jaw, then perhaps you'll need a doctor.
The most common problem with jaw pain is TMJ, or Temporomandibular Joint disorder, which has to do with jaw alignment and pain at the connective muscles in the face. It is highly treatable, but most people don't seek treatment at all. But, by all means, don't take my diagnosis on eNotes - get thee to a physician or dentist.
