WHAT ARE TMJ DISEASES AND DISORDERS?
TMJ diseases and disorders are a group of
conditions that cause pain in and around
the jaw joint (called the Temporomandibular
Joint or TMJ) and nearby muscles. Jaw problems
affect a person’s ability to speak, eat,
chew, swallow, and even breathe.
WHAT ARE THE SYMPTOMS OF TMJ DISEASES AND
DISORDERS?
Pain is the most common symptom; however,
some people have no pain but still have problems
using their jaws.Symptoms can include:
Face pain
Pain in the jaw joint and nearby areas, including
the ear
Being unable to open the mouth comfortably
Clicking, popping or grating sounds in the
jaw joint
Locking of the jaw when attempting to open
the mouth
Headaches
A bite that is uncomfortable or feels “off”
Swelling on the side of the face Neck, shoulder,
and back pain
Other symptoms may include: ringing in the
ears, ear pain, decreased hearing, dizziness,
and vision problems.
Keep in mind that occasional discomfort in
the jaw joint or chewing muscles is common
and is not a cause for concern. Many people
with TMJ problems get better without treatment.
Often the problem goes away on its own in
several weeks to months.
WHAT CAUSES TMJ DISEASES AND DISORDERS?
Not all causes are known. Some possible causes
are injuries to the jaw area, various forms
of arthritis, some dental procedures, stretching
of the jaw as occurs with inserting a breathing
tube before surgery, and clenching or grinding
of teeth.
HOW ARE TMJ DISEASES AND DISORDERS TREATED?
Reversible Treatments
According to the National Institute of Dental
and Craniofacial Research of the National
Institutes of Health, TMJ treatments should
be reversible whenever possible. That means
that the treatment should not cause permanent
changes to the jaw or teeth.
Examples of reversible treatments are:
Over-the-counter pain medications
Prescription medications
Gentle jaw stretching and relaxation exercises
Stabilization splints (biteplate, nightguard)
Irreversible Treatments
According to the National Institute of Dental
and Craniofacial Research of the National
Institutes of Health, irreversible treatments
have not been proven to work and may make
the problem worse.
Examples of irreversible treatments are:
Adjustment of the bite by grinding the teeth
Extensive dental work
Mandibular repositioning splints
Orthodontics
Surgical procedures including replacement
of all or parts of the jaw joint
ARE TREATMENTS FOR TMJ DISEASES AND DISORDERS
COVERED BY INSURANCE?
Many medical and dental insurance plans do
not pay for the treatment of jaw joint and
muscle disorders, or only pay for some procedures.
Contact your insurance company to see which
treatments are covered.
FUTURE RESEARCH
Much more research is needed. Scientists
do not clearly understand what causes most
TMJ problems, how to diagnosis them, how
to treat them effectively, and how to prevent
them from happening.
In recent years, The TMJ Association, a national
patient advocacy organization, has co-sponsored
three international scientific meetings with
the National Institutes of Health to address
these areas of concern. Details about these
meetings and extensive information on TMJ
diseases and disorders can be found on The
TMJ Association’s Web site, www.tmj.org.
