Osteomyelitis is an infection of the bone. The temporomandibular joint is rarely affected by osteomyelitis, but when it is, it requires immediate attention. Lack of jaw and neck mobility may occur during and after the infection, and physical therapy will help improve your jaw mobility to restore your ability to eat, speak, and brush your teeth.

Physical therapists are movement experts. They improve quality of life through hands-on care, patient education, and prescribed movement. You can contact a physical therapist directly for an evaluation. To find a physical therapist in your area, visit Find a PT.

What Is Osteomyelitis of the Jaw?

Osteomyelitis is an infection of the bone and most commonly affects the bones of the extremities, spine, and pelvis. The temporomandibular joint, or TMJ, is rarely affected by this condition, but when it is, serious problems with the bones of the face and jaw can result.

Usually, the infection is the result of bacteria entering the body through poor oral hygiene or oral surgery, such as a root canal procedure. It also may occur following a jaw fracture. Osteomyelitis in the jaw occurs more in men than women, and more commonly in the mandible (lower jaw bone) than the maxilla (bone where the top teeth are arranged). People with diabetes, have alcoholism, or other diseases that impact the immune system are at greater risk. Having had another recent surgery before oral surgery or jaw trauma may increase risk, also.

To heal the infected bone, the body sends white blood cells to the area; however, persistent presence of white blood cells near the bone actually causes the bone to break down. The infection restricts blood flow to the area and causes bone death ("necrosis").

Signs and Symptoms

Osteomyelitis of the jaw can cause:

  • Fever.
  • Jaw pain.
  • Facial swelling.
  • Tenderness to the touch.
  • Jaw stiffness.
  • Sinus drainage.
  • Tooth loss.
  • Pus (thick, usually yellow-white fluid).
  • A palpable bump on the bone of the jaw.
  • Fatigue.
  • Fever.
  • Headaches or neck ache.

During the acute stage of osteomyelitis, you'll have increasing, constant jaw pain and sinus pressure that is not affected by movement of the jaw. If you have chronic osteomyelitis, you may have jaw and neck stiffness, and difficulty with eating and talking.

How Is It Diagnosed?

A series of blood tests usually is ordered to check for elevated white blood cell counts. This condition is often misdiagnosed because its symptoms are similar to other jaw, skull, or face problems. Bone changes and inflammation may be observed in medical images (x-ray, ultrasound, CT, or MRI) of the jaw, as well.

If osteomyelitis is found to be the cause of your pain, your physician will prescribe antibiotics to clear up the infection. Occasionally, there is difficulty opening the mouth, normally due to tissue damaged by the inflammation. In these cases, physical therapy will help restore motion and decrease pain in the jaw area. Your doctor or dentist will inform your physical therapist what specific areas were impacted by the infection. The physical therapist then can help you restore the normal motion and mobility of those structures, reduce your pain, and gain the ability to speak, eat, and maintain oral hygiene.

How Can a Physical Therapist Help?

Your physical therapist can help restore the natural movement of your jaw and decrease your pain; but first, the antibiotics need to take effect. After you've finished your antibiotics, you might have pain and limited movement at the TMJ and cervical spine. You also might have headaches.

During your first visit with your physical therapist, the therapist will:

  • Review your medical history, and discuss any previous surgery, fractures, or other injuries to your head, neck, or jaw
  • Conduct a physical examination of your jaw and neck
  • Evaluate your posture and how your neck moves
  • Examine the TMJ to find out how well your mouth can open and whether there are any abnormalities in jaw motion as a result of the osteomyelitis

The therapist might place his or her hand in your mouth in order to examine your jaw movement.

Following the examination, the physical therapist will select appropriate treatments to improve jaw movement and relieve pain.

Improve Jaw Movement

Physical therapists use skilled hand movements called manual therapy  to increase movement and relieve pain in tissues and joints. Your therapist also might use manual therapy to "stretch" the jaw to:

  • Restore normal joint and muscle flexibility (so that you won't feel "tight")
  • Break up the scar tissues ("adhesions") that may occur when disease or injury limits movement for a period of time

Your physical therapist may teach you special "low-load" exercises. These are exercises that don't exert a lot of pressure on your TMJ but can strengthen the muscles of the jaw and restore a more natural, pain-free motion. The therapist will also teach you exercises that help you increase the opening of your jaw and improve the way your jaw works

Relieve Your Pain

In addition to manual therapy, if your pain is severe, your physical therapist might use treatments such as electrical stimulation or ultrasound to reduce pain.

Can This Injury or Condition Be Prevented?

Prevention of infection starts with maintaining a healthy lifestyle. Your body fights infections best when you have proper rest, nutrition, and hygiene, such as hand washing and tooth brushing.

If you need oral surgery, the dentist or doctor's technique can be the start of avoiding infection. However, you should take antibiotics as prescribed after any surgery, as everyone's mouth has a significant amount of bacteria present. These bacteria do not pose a threat in normal circumstances.

After any procedure, you will be given instructions about how to care for the healing area. For instance, after wisdom tooth removal you can prevent infection by following directions for how and when to clean the area, and using gauze to pack the wound. You may need to alter your diet to protect the area, while allowing open wounds in the mouth to heal.

If you notice any signs and symptoms of infection, or something doesn’t seem correct with your mouth and jaw, calling the office can avoid progression of any problems.

What Kind of Physical Therapist Do I Need?

All physical therapists are prepared through education and experience to treat patients who have osteomyelitis. You may want to consider:

  • A physical therapist who is experienced in treating people with orthopedic or musculoskeletal problems. Some physical therapists have a practice with a craniofacial focus, meaning that they focus on movement disorders related to the skull and facial structures, and often specialize in treating the temporomandibular joint (jaw joint).

You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you're looking for a physical therapist (or any health care provider):

  • Get recommendations from family and friends or from other health care providers.
  • When you contact a physical therapy clinic for an appointment, ask about the physical therapists' experience in helping people with osteomyelitis.
  • Be prepared to describe your symptoms in as much detail as possible, and say what makes your symptoms worse.
