It might be hard to get out of bed when you have a jaw ache. Understanding what is causing the ache in your jaw may help you take steps to alleviate it.
The first step in addressing jaw pain is knowing the cause. There are many possibilities.
Teeth grinding or teeth clenching
One of the most likely causes of your morning jaw pain is bruxism. That’s the medical term for teeth grinding. You may be grinding your teeth or clenching your jaw in your sleep without realizing it.
Cavities or gum disease
Tooth cavities usually develop first in the outer layers of a tooth. If untreated, the decay can spread into the inner layers of a tooth and down to the root and surrounding bone. The result: a throbbing jaw.
Periodontitis, or gum disease, can be a cause, too. Periodontitis usually starts out as inflammation in your gums from an accumulation of bacteria, as well as from a buildup of plaque on your teeth. Without treatment, it can work its way down into your bones and other tissues and cause significant pain.
You have some sinuses close to the roots of your upper teeth and your jawbone. And when those sinuses fill with fluid, the congestion can create pressure on your teeth and jawbone. Sinus infections or sinus inflammation can make your jaw ache.
If you have woken up with a stiff neck, you know that sleeping position can cause some pretty annoying pains. If you sleep on your stomach or side, you may put pressure on your jaw. When your alarm clock rings in the morning, your jaw hurts.
Temporomandibular disorders can affect your two temporomandibular joints, which connect your lower jaw to your skull. A temporomandibular joint disorder can cause pain in your jaw, face, and neck, as well as stiffness in your jaw. It might even limit your ability to move your jaw or cause a malocclusion, or misalignment, of your teeth.
Third molars, better known as wisdom teeth, might be notorious for causing jaw pain. Often, there’s not enough room for this last set of teeth to fully erupt, so they can put pressure on the other teeth. They can grow in crooked and cause misalignment, which can be painful. And they often get impacted, or stuck in your jaw and unable to completely erupt through the gums, which can cause pain and stiffness in your jaw.
The underlying cause of jaw pain can be treated.
- Bruxism. Sleeping with a mouthguard or bite guard is a fairly easy, noninvasive way to protect your teeth from damage and reduce some strain on your jaw.
- Teeth clenching. Practicing a few simple tongue and jaw exercises may help you relax tight muscles and align your jaw properly.
- Cavities and gum disease. A dentist may likely recommend a cavity filling, crown, or other procedure, such as extracting a tooth that is beyond saving if the root or gums become severe.
- Sinus pain. You can try a home remedy like breathing in hot, steamy air or rinsing your sinuses with a spray or neti pot to try to alleviate some congestion and pain. An over-the-counter (OTC) pain reliever or allergy medicine might help, too. But if a doctor suspects you have a bacterial infection in your sinuses, you may need an antibiotic.
- Sleeping position. You may have to change up your sleeping position if you’re a stomach or side sleeper. One 2018 study suggested that sleeping on your back can be a great option to help avoid putting strain on your jaw or your temporomandibular joints, and possibly for exacerbating problems from a TMJ disorder you may have.
- TMJ disorder. The treatment may vary, depending on which type of TMJ disorder you have. It could include pain medication, heat therapy, cooling therapy, or corrective dental treatments. Some doctors even suggest Botox injections, although the
evidence of the effectiveness is very limited.
- Wisdom teeth. Your dentist can give you advice about whether to undergo oral surgery to remove some or all of your wisdom teeth. In the meantime, an ice pack or OTC pain reliever may help you out.
Jaw pain can be caused by a short-lived illness. Sometimes a doctor can prescribe additional treatment for a sinus infection.
Other causes of jaw pain, such as tmd pain or teeth grinding, can justify a dentist talking to them. Your dentist can help you figure out the cause of the jaw pain.
If your quality of life is affected, it is a good idea to call a medical professional.
You may be tempted to take an OTC pain relief immediately after you wake up because your jaw feels sore. If you want to be checked out by a medical professional, consider it. If the pain seems to be constant, you should call a dentist or doctor.
