You expect a decayed tooth, a fracture or a gum infection to be the cause for that toothache causing you grief. Sometimes, though, the answer may be “none of the above”—there's nothing wrong going on in your mouth to cause the pain.
You pain is real—but its source is elsewhere in the body, a situation known as referred pain. It's important to find out the pain's true source to determine what kind of treatment you'll need to alleviate it.
Here are some of the likely candidates for a “toothache” that's not a toothache.
Facial nerves. Tooth pain may be associated with trigeminal neuralgia, a misfiring disorder of the trigeminal nerves that course through either side of the face. The nerve is divided into three branches, two of which are located in the upper face and one in the lower jaw. Because they're interconnected, a problem with one of the branches in other parts of the face could be felt in the branch around the jaw.
Jaw joints. Temporomandibular Joint Disorders (TMD) can cause pain in the pair of joints that connect the lower jaw to the skull. The joints can become inflamed due to stress or trauma and the associated muscles begin spasming, causing severe pain. Because of their proximity to the teeth, the pain from the joints can radiate into the dental area and mimic a toothache.
Ear or sinus infections. Both the ears and the maxillary sinus are subject to infections that can cause severe pain and pressure. With the close proximity of both the ears and the sinus to the upper jaw, it's quite possible for pain originating in these structures to be felt within the mouth.
These are only a few of the possibilities that also include migraines, shingles, fibromyalgia and even vitamin deficiencies. As such, your dentist or physician may need to do a little detective work to locate the true cause. But the effort to locate where your mouth pain is actually coming from will help ensure you get the right treatment to give you lasting relief.
