Jaw mobility FAQs

Below are some frequently asked questions, tips and techniques for using TheraBite. If you have a question that is not listed here, please contact our Customer Service Team at 800.217.0025. We are here to help!

What is TMJ Disorder?

The temporomandibular joint (TMJ) is used in all jaw movements and is commonly referred to as the jaw joint. Patients with TMJ disorders (TMD) may suffer from limited jaw movement and/or orofacial pain in the joint and muscle area.

Signs and symptoms of TMJ disorders may include:

  • Pain or tenderness of your jaw
  • Aching pain in and around your ear
  • Difficulty chewing
  • Aching facial pain
  • Locking of the joint, making it difficult to open or close your mouth
  • Headache
  • Uncomfortable bite
  • Reduced mouth opening

Studies have shown that stretching combined with therapeutic motion are effective ways to improve jaw mobility. Therapeutic motion nourishes the joint without activating painful muscles.

What are the symptoms of TMJ Disorders and are there treatment options?

Our lower jaw supports important muscles, joints and teeth vital for chewing, speaking, swallowing and making facial impressions. Any restrictions in our jaw motion may jeopardize these functions. Limited or absent joint movement may lead to inflammation, causing the joint to stiffen and gradually lose functionality. Possible causes for limited jaw movement are for example facial trauma, rheumatoid arthritis, jaw clenching and fibromyalgia.

Training with the TheraBite System provides both stretching and therapeutic motion.

What is Trismus?

Trismus (mandibular hypomobility) is a condition that refers to any restriction in opening the mouth, or in jaw mobility. It is a severe, yet frequently overlooked, disability. Patients often suffer chronic pain and have difficulty with day-to-day functions, such as biting, chewing, oral hygiene, and speech..

Trismus can be caused by:

  • Radiation therapy to the head and neck
  • Surgery involving the head and neck
  • Temporomandibular joint disorders (TMD)
  • Infections
  • Systemic diseases, e.g. rheumatoid arthritis or scleroderma
  • Direct trauma to the head and neck
  • Indirect trauma, e.g. whiplash
  • Facial burns
  • Stress-induced disorders, e.g. clenching and grinding of the teeth (bruxism)
  • Congenital (at birth) or hereditary diseases
  • Aging

What are the symptom of Trismus and are there treatment options?

Trismus is a severe, yet frequently overlooked, disability. Patients often suffer chronic pain and have difficulty with day-to-day functions, such as biting, swallowing, chewing, oral hygiene, and speech.

Atos Medical AB manufactures the TheraBite® Jaw Motion Rehabilitation System™. It is a portable system specifically designed to treat trismus and mandibular hypomobility.

What is the TheraBite System and what is it used for?

The TheraBite Jaw Motion Rehabilitation System is a manually operated, intermittent passive motion system indicated for persons with restricted jaw motion or pain in the joint and/or muscles of mastication (chewing). A key aspect of the TheraBite system is that it follows normal jaw movement.

Why is TheraBite system more effective than conventional therapies?

While most conventional therapies rely on stretching to increase jaw mobility, the TheraBite system focuses not only stretching (in comfortable and anatomically correct manner), but also on passive motion to strengthen muscle and mobilize joints.

Is there any way I can make the Bite Pads stick better, or last longer?

Make sure that the mouthpiece surface is completely dry before applying the Bite Pads. As pressure and warmth increase the Bite Pads’ adhesion to mouthpieces, you can use your thumb to press and “massage” the Bite Pads when they are correctly positioned on the mouthpieces. Another tip is to leave the Bite Pads on the mouthpieces overnight before starting to use the device (the longer the Bite Pads stay on before use, the greater their adhesion strength).

How often should I change my Bite Pads?

Bite pads should last around 6 weeks. Placing the device under running water, or cleaning it, does not affect adhesion of the Bite pads.

Do you have tips or techniques designed to help assist patients and their family members?

Yes!  We have developed several CareTip Information Sheets as an educational resource for both patients healthcare professionals.  View our Atos CareTips here.
