A toothache means a tooth has a problem, right? Most of the time, yes: the pain comes from a decayed or fractured tooth, or possibly a gum infection causing tooth sensitivity.
Sometimes, though, the pain doesn't originate with your teeth and gums. They're fine and healthy—it's something outside of your tooth causing the pain. We call this referred pain—one part of your body is sending or referring pain to another part, in this instance around your mouth.
There are various conditions that can create referred pain in the mouth, and various ways to treat them. That's why you should first find out the cause, which will indicate what treatment course to take.
Here are a few common non-dental causes for tooth pain.
Trigeminal Neuralgia. The trigeminal nerves situated on either side of the face have three large branches that extend throughout the face; the branch to the jaw allows you to feel sensation as you chew. When one of the nerve branches becomes inflamed, usually from a blood vessel or muscle spasm pressing on it, it can refer the pain to the jaw and seem like a toothache.
Temporomandibular Joint Disorder (TMD). These two joints that connect the lower jaw to the skull can sometimes become dysfunctional for a variety of reasons. This can set up a cycle of spasms and pain that can radiate throughout the jaw and its associated muscles. The pain can mimic a toothache, when it actually originates in the jaw joints.
Teeth Grinding. This is an unconscious habit, often occurring at night, in which people clench or grind their teeth together. Although quite common in children who tend to grow out of it, teeth grinding can continue into adulthood. The abnormally high biting forces from this habit can cause chipped, broken or loosened teeth. But it can also cause jaw pain, headaches and tenderness in the mouth that might feel like a toothache.
These and other conditions unrelated to dental disease can seem like a tooth problem, when they're actually something else. By understanding exactly why you're feeling pain, we can then focus on the true problem to bring relief to your life.
People who fly or scuba dive know firsthand how changes in atmospheric pressure can affect the body: as minor as a popping in the ears, or as life-threatening as decompression sickness. Pressure changes can also cause pain and discomfort in your teeth and sinuses — in fact, severe pain could be a sign of a bigger problem.
Barotrauma (baro – “pressure;” trauma – “injury”), also known as a “squeeze,” occurs when the unequal air pressures outside and inside the body attempt to equalize. Many of the body's organs and structures are filled with air within rigid walls; the force created by equalization presses against these walls and associated nerves, which in turn causes the pain.
The sinus cavities and the middle ear spaces are especially sensitive. Each of these has small openings that help with pressure equalization. However, they can become swollen or blocked with mucous (as when you have a head cold), which slows equalization and contributes to the pain.
It's also possible to experience tooth pain during pressure change. This is because the back teeth in the upper jaw share the same nerve pathways as the upper jaw sinuses — pain originating from the sinuses can be felt in the teeth, and vice-versa. In fact, it's because of this shared pathway that pressure changes can amplify pain from a tooth with a deeper problem, such as a crack, fracture or a defect in dental work.
Besides problems with your teeth, the severe pain could also be related to temporo-mandibular joint dysfunction (TMD), which is pain or discomfort in the small joint that connects your lower jaw to your skull. There are a number of causes for this, but a common one for scuba divers is an ill-fitted regulator mouthpiece that they are biting down on too hard while diving. A custom-fitted mouthpiece could help alleviate the problem.
If you've been experiencing tooth pain during pressure change events, you should see us for an examination before you fly or dive again. There might be more to your pain — and correcting these underlying problems could save you extreme discomfort in the future.
