Rheumatoid Arthritis Of The Temporomandibular Joint
As a synovial joint, patients with RA are at risk of TMJ involvement, and 6771% patients will have at least one symptom however, the true prevalence depends on the population studied, diagnostic criteria, and means of TMJ assessment . The likelihood of TMJ involvement correlates with the severity and duration of the systemic disease as tenderness in multiple peripheral joints is often accompanied by a painful TMJ . Typical clinical findings include joint pain, stiffness, sounds, and limitation of movement . TMJ pain and masticatory muscle tenderness suggest an active disease .
Rheumatoid arthritis patients tend to have more frequent and severe symptoms, signs, and radiographic changes when compared with PA and AS . Crepitus, in particular, is considered to be an important sign of joint destruction . Typical radiographic changes include cortical erosions, subcortical cysts, flattening of the condylar head and articular eminence, subcortical sclerosis, and narrowing of the joint space, but none of these are pathognomonic of RA .
Difficulty in mouth opening is common in RA due to pain, fibrous adhesions, anterior disc displacement, muscle contracture, inflammation, or more severe degeneration of the TMJ. However, when measured objectively, there is no statistically significant difference between the mouth opening of patients with RA and the general population, so this finding in itself does not yield a definitive diagnosis .
Medications For Jaw Pain
It was a relief to find that just as DMARDs and biologics work for knees and hands, they also work for jaws.
If you dont already, your doctor may add other anti-inflammatory medications to your treatment regimens during jaw flares to reduce the inflammation and help prevent damage and interruptions to life. However, this may not be necessary if other, simpler therapies seem to be effective.
What Are The Most Common Symptoms Of Tmj Problems
People who have TMD may experience radiating pain from the joints, stiffness in their jaws, changes in the way their teeth align and locking of their jaws. Some people may have trouble eating hard or chewy foods. You may become aware of a scraping noise from inside your jaw. You may also experience clicking in your jaw when you move it. While many people believe that the clicking itself is the cause of TMD, it is most likely just another symptom.
Not all jaw pain and TMJ problems are due to arthritis. Other people may experience issues due to the muscle issue myofascial pain, joint damage or trauma to the area.

What Is Temporomandibular Disorder
Temporomandibular disorders are disorders of the jaw muscles, temporomandibular joints, and the nerves associated with chronic facial pain. Any problem that prevents the complex system of muscles, bones, and joints from working together in harmony may result in temporomandibular disorder.
The National Institute of Dental and Craniofacial Research classifies TMD by the following:
Myofascial pain. This is the most common form of TMD. It results in discomfort or pain in the fascia and muscles that control jaw, neck and shoulder function.
Internal derangement of the joint. This means a dislocated jaw or displaced disk, , or injury to the condyle .
Degenerative joint disease. This includes osteoarthritis or rheumatoid arthritis in the jaw joint.
You can have one or more of these conditions at the same time.
About Jaw Joint Problems
Your jaw joint connects your lower jaw to your skull. It allows your mouth to open and close so you can speak and chew. Lots of muscles and ligaments help your jaw move up and down, from side to side, and backwards and forwards.
If you have a problem with your jaw joint or the muscles around it, this is usually called temporomandibular jaw disorder. Some doctors also call it myofascial pain disorder.
Up to seven in every 10 people in the UK have a problem with their jaw joint at some point in their lives. You can get problems with your jaw at any age, but its most likely to happen when youre aged between 20 and 40.

When Psa Invades The Jaw
PsA can affect the TMJ, just like any other joints in your body.
When Candace Primack of Scottsdale, Arizona, started to feel a sharp pain in her left ear in her law class one day, she didnât know what to do. All she knew was that the slightest movement made the pain that much worse.
After consulting with multiple otolaryngologists who could not provide any meaningful insight into her condition, she realized that the unanswered questions had also baffled a majority of medical professionals she had been seeing. It wasnât until she was referred to a dentist who specialized in the temporomandibular joint that the cause of her pain was found â a cause that shocked Primack: psoriatic arthritis .
TMJs are the joints that connect the jawbone to the skull. PsA can affect the TMJ, just like any other joints in your body. An estimated 35 percent of people with PsA will experience symptoms in their TMJ. Despite those high numbers, there still seems to be quite a bit of confusion when it comes to treating PsA in the jaw.
Causes Of Osteoarthritis In The Jaw
A common cause of osteoarthritis in the jaw could be that the person affected has put their jaw under excessive strain over a very long period. For example, this could come from a habit of clenching the jaws or grinding the teeth. Many people have a tendency to do this at night without being aware of it. If you think that this is the cause of sore jaw joints, you should visit your dentist to have it checked.
Osteoarthritis in the jaw can also be a form of post-traumatic osteoarthritis. This means that the disease has developed from earlier damage to the joint or trauma to your jaw, for example a punch. Heredity is also a factor that can affect the development of osteoarthritis.

What Are Common Tmj Symptoms
TMJ dysfunction is most common in those 20 to 40 years of age and is more common in women than in men. Some of the most common TMJ symptoms include:
- Jaw pain.
- Pain in the neck or shoulders.
- Difficulty opening your mouth wide.
- Jaws that “lock” in the open- or closed-mouth position.
- A tired feeling in your face.
- Difficulty chewing.
- Tinnitus, or ringing in your ears.
- Changes in the way your teeth fit together.
- Swelling on the side of your face.
- Tooth pain.
What Treatments Are Available For Tmj Disorders
Treatments range from simple self-care practices and conservative treatments to injections and open surgery. Most experts agree that treatment should begin with conservative, nonsurgical therapies, with surgery left as the last resort. Weâll explore a variety of TMJ treatments in the sections below.

What Are The Temporomandibular Joints
The temporomandibular joints are the 2 joints that connect your lower jaw to your skull. More specifically, they are the joints that slide and rotate in front of each ear, and consist of the mandible and the temporal bone . The TMJs are among the most complex joints in the body. These joints, along with several muscles, allow the mandible to move up and down, side to side, and forward and back. When the mandible and the joints are properly aligned, smooth muscle actions, such as chewing, talking, yawning, and swallowing, can take place. When these structures are not aligned, nor synchronized in movement, several problems may occur.
Are There Alternative Tmj Treatments Available
Many healthcare providers recommend using alternative therapies in combination with traditional treatments. These therapies may include:
- Relaxation techniques. Mindfulness or meditation can help you slow your breathing and relax tense muscles. As a result, pain can be reduced.
- Acupuncture. This technique involves inserting thin needles into the body at various points. Acupressure points may trigger the central nervous system and stimulate your bodyâs natural healing processes.
- Biofeedback. Electronic instruments can be used to detect areas of stress and tightness in your body. This gives you a greater awareness of where youâre holding tension so you can focus on relaxing these muscles.
- Pain management referrals. In some cases, you may be referred to a pain psychologist or pain management clinic to help ease your symptoms.

Cause Of Arthritis In The Jaw
The main cause of this type of arthritis is persistent overload of the jaw joint. Tooth grinding is a good example of that. This occurs if you grind your teeth during sleep and shake with strong force or pinch them firmly. During the tooth grinding, a large amount of pressure is applied to the cartilage in the jaw joints. As a result, it can wear off. The quality of this discus may also deteriorate due to jaw fracture or rheumatoid arthritis. In this rheumatic condition, the cartilage is affected by inflammatory processes going on in the joint.
Physical Therapy For Jaw Pain
Its my least favorite thing in the world, but is invaluable for anyone with arthritis of the jaw. The exercises and stretches your doctor or physical therapist will give you tend to be very simple and can be done while watching TV, and some can even be done while doing laundry or driving .
These exercises need to be done frequently, but often only for a few minutes at a time and tend to help the pain immediately.

Psoriatic Arthropathy Of The Temporomandibular Joint
Traditionally, TMJ involvement in PA has been thought to be rare with fewer than 40 cases reported in the last 50 years. However, some studies have suggested that dysfunction occurs in 90% patients with PA . More recently, Dervis and Dervis found the TMJ to be symptomatic in 29% and 35% of patients with psoriasis and PA, respectively. This incidence is no higher than that found in the general population without psoriasis therefore, PA does not necessarily increase the risk of TMJ dysfunction. However, when it occurs, the symptoms tend to be worse. PA can also affect the TMJ in the form of monoarthritis, rather than polyarthritis in 0.010.2% of the population .
The duration and severity of PA and the number of somatic joints affected are the main risk factors for TMJ symptoms and signs, but the degree of skin involvement is not . Typical findings include clicking, crepitus, or other joint sounds TMJ pain on mouth opening and chewing morning stiffness and muscle tenderness . As the disease progresses, pain is replaced by the limitation of movement due to the development of fibrosis. Like RA, crepitus is found in the latter stages and is associated with structural joint changes, which may progress to joint collapse or ankylosis.
Home Remedies For Arthritis Jaw Pain
You can also try a few simple treatments and behavior modifications to treat jaw pain, and reduce your risk of having it in the first place:
- Eat softer foods
- Apply heat and/or ice. Ice tends to help me numb it out, Hannah M. told us on Facebook.
- Keep up with oral hygiene
- Try an arthritis pain cream. I put a bit of Tiger Balm on the tip of the jaw near the front of the ear, that where it was the most sore, Hannah said on FB.
- Dont chew gum, Karin says. Repetitive chewing motions, like chomping gum or biting your nails, put too much strain on the jaw.

Take Hold Of The Situation
Primackâs PsA journey, which has led her to jaw replacement surgery, is an extreme case, according to Ana-Maria Orbai, M.D., an assistant professor of rheumatology at Johns Hopkins University in Baltimore, Maryland, and an NPF medical board member. She says that for most people, treating PsA in the jaw should follow the same playbook for treating PsA in any other part of the body.
âIf people have symptoms of inflammation in the jaw caused by psoriatic arthritis, treatment can be established and adjusted to avoid long-term damage,â says Orbai.
The range of treatment options, including biologics and oral medications like disease-modifying antirheumatic drugs, should work for preventing or slowing the degradation of the TMJ as it does in any of the other joints, says Orbai.
The TMJ is connected to the strongest muscle in the body, the masseter muscle â therefore it is a very hard-working joint and at risk for damage. She also recommends some common-sense lifestyle changes that people can make. âYou can take an anti-inflammatory and stop chewing hard foods like almonds to decrease pressure on the jaw.â
Checking in with the dentist to rule out other causes of TMJ pain is critical as well. When in doubt, imaging techniques such as radiographs and MRI can differentiate between damage and inflammation. A custom mouthpiece to wear at night may also help individuals who are experiencing jaw misalignment or teeth-grinding.
Treatment Options For Jaw Pain
Unfortunately, there is no officially accepted medical specialty or accepted standards of care for TMD. According the non-profit TMJ Association, treatments may include eating soft foods, ice and heat packs, pain medications, exercises, relaxation, side sleeping, avoiding chewing gum, dental splints, and limited cortisone injections. They highly recommend avoiding treatments that cause permanent changes in the jaw or bite. Surgery is not recommended because of lack of scientific evidence.11

How Neck Arthritis Is Diagnosed
Your doctor will start by taking a history and doing a physical exam. Theyll check the range of motion in your neck and test your strength, sensation, and reflexes to find out if there is pressure on your nerves or spinal cord. Theyll ask when your symptoms started, when the pain happens, and what makes the pain better and worse.
Your doctor may order an X-ray to assess alignment and look for arthritic changes, says Dr. Shah. If there is a concern of compression of spinal nerves or the spinal cord, you may need an MRI to look at the neutral structure and discs, says Dr. Shah.
A CT scan may be ordered to look at the bone more closely, especially to see if any bony outgrowths are causing compression. However, X-rays and MRIs are the tests that are usually ordered, says Dr. Shah. A CT scan with a myelogram may be used if an MRI cant be done.
An electromyography, or EMG, may be ordered to assess for nerve compression, says Dr. Shah. An EMG tests the electrical conduction of the nerves in the arms. This test would be helpful if you have multiple nerves being compressed or compression of nerves at the neck and in the arm, he says.
Your doctor may order blood tests to see if you have any antibodies or systemic inflammation that would reveal inflammatory arthritis, such as rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis.
What Are Some Other Tmj Treatments
If conservative treatments are unsuccessful, your healthcare provider may suggest one or more of the following:
- Transcutaneous electrical nerve stimulation . This therapy uses low-level electrical currents to reduce pain by relaxing your jaw joint and facial muscles. TENS can be completed at home or your healthcare providerâs office.
- Ultrasound. This is a deep heat treatment that is applied to the TMJ to relieve soreness or improve joint movement.
- Trigger-point injections. Pain medication or anesthetic is injected into tender muscles of the face to relieve pain.
- Radio wave therapy. Radio waves create a low-level electrical stimulation to the joint, which increases blood flow and provides TMJ relief.
- Botulinum Toxin . These injections help reduce muscle mass and inflammation.

Symptoms Of Jaw Joint Problems
If you have a problem with your jaw joint, you may:
- have a dull aching pain around your jaw, cheek, ear, neck, shoulders or back
- find it hard to move your jaw when you try to speak or chew
- feel like your jaw is locked in position when you try to open your mouth
- find it hard to open your mouth wide or close it easily
- hear popping, grating or clicking sounds when you move your jaw
- get headaches
- get pain in your ears, tinnitus , and dizziness
- notice your bite doesnt feel as comfortable as usual
You may find that your jaw pain gets worse during the day or when you chew or talk. You may be able to manage these symptoms at home and they often get better on their own. But if youre worried about the pain or your symptoms are getting worse, make an appointment with your dentist to find out if treatment could help.
When Should Someone Seek Medical Care For Tmj
Occasional pain in the jaw joint or chewing muscles is common and may not be a cause for concern. See a doctor if your pain is severe or if it does not go away. You should also see your health-care professional if it hurts to open and close the jaw or if you have difficulty swallowing food. Treatment for TMJ syndrome ideally should begin when it is in the early stages. If the condition is identified early, the doctor can explain the functioning of the joints and how to avoid any action or habit that might aggravate the joint or facial pain.
If your jaw is locked open or closed, go to a hospital’s emergency department.
- The open locked jaw is treated by sedating you to a comfortable level. Then the mandible is held with the thumbs while the lower jaw is pushed downward, forward, and backward. This maneuver is usually done by the Emergency Department physician or an ear, nose, and throat specialist.
- The closed locked jaw is also treated by sedating you until you are completely relaxed. Then the mandible is gently manipulated until the mouth opens.
