Picture of Temporomandibular Joint (TMJ) Syndrome
Temporomandibular joint (TMJ) syndrome is a pain in the jaw joint that can be caused by a variety of medical problems. The TMJ connects the lower jaw (mandible) to the skull (temporal bone) in front of the ear. Certain facial muscles that control chewing are also attached to the lower jaw. Problems in this area can cause head and neck pain, facial pain, ear pain, headaches, a jaw that is locked in position or difficult to open, problems with biting, and jaw clicking or popping sounds when you bite. The temporomandibular joint syndrome is also referred to as the temporomandibular joint disorder. Overall, more women than men have TMJ syndrome.
The TMJ is comprised of muscles, blood vessels, nerves, and bones. You have two TMJs, one on each side of your jaw.
Muscles involved in chewing (mastication) also open and close the mouth. The jawbone itself, controlled by the TMJ, has two movements: rotation or hinge action, which is opening and closing of the mouth, and gliding action, a movement that allows the mouth to open wider. The coordination of this action also allows you to talk, chew, and yawn.
If you place your fingers just in front of your ears and open your mouth, you can feel the joint and its movement. When you open your mouth, the rounded ends of the lower jaw (condyles) glide along the joint socket of the temporal bone. The condyles slide back to their original position when you close your mouth. To keep this motion smooth, a soft disk of cartilage lies between the condyle and the temporal bone. This disk absorbs shock to the temporomandibular joint from chewing and other movements. Chewing creates a strong force. This disk distributes the forces of chewing throughout the joint space.
Ongoing studies conducted by the National Institute of Dental and Craniofacial Research (NIDCR), part of the U.S. National Institutes of Health, are focused on evaluating risk factors for TMJ syndrome in healthy individuals. Initial results have identified a group of physiological, psychological, sensory, and genetic and nervous system factors that may increase the risk of developing TMJ syndrome. New findings will allow us to better understand the onset and progression of TMJ syndrome. Furthermore, novel ways to diagnose and treat the condition can be developed. Below are some risk factors that have been identified:
Gender: Women are at higher risk of developing TMJ syndrome compared to men. Additionally, there may be differences in how women and men respond to pain and to pain medications.
Age: Studies of individuals between the ages of 18-44 show that the risk to develop TMJ conditions increases for women. This has been noted especially for women during their childbearing years. For men ages 18-44, there was no increased risk.
Pain tolerance: Studies suggest that people who are more sensitive to mildly painful stimuli have an increased risk of developing TMJ syndrome.
Genetics: There is some indication that genes related to stress response, psychological health, and inflammation may increase the risk for TMJ syndrome.
Chronic pain: Those who suffer from chronic pain conditions such as lower back pain and headaches may be at increased risk for TMJ syndrome.
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 (such as chewing gum) that might aggravate the joint or facial pain.
If your jaw is locked open or closed, go to a hospital’s emergency department.
Depending on the what doctor suspects as the cause, he/she may order blood tests that include a white cell count and other tests to rule out lupus, rheumatoid arthritis, or gout as a cause of the TMJ syndrome.
If the diagnosis of TMJ syndrome is not clear or some other disorder is suspected, CT or MRI scans may also be obtained The MRI scan can help assess the soft tissues and the inside of the joint. A CT scan can help assess the bony structures and muscles. Experts believe that in doubtful cases, MRI is the study of choice as it is useful in evaluating TMJ disease.
In rare cases, if all the above tests fail to make a diagnosis of TMJ syndrome and pain still persists, the surgeon may use a needle to clean and irrigate the joint (arthrocentesis).
In the majority of cases, TMJ syndrome is self-limiting. Most of the symptoms disappear in two weeks once the jaw is rested There are a variety of options for treating TMJ syndrome at home.
For chronic TMJ syndrome, a team approach is usually required. This may include a dentist, ENT surgeon, pain specialist, physiotherapist, and a primary care physician. Modalities used to relieve pain and restore the function of the TMJ may include the use of splints, physical therapy, psychological counseling, acupuncture, hypnotherapy, and arthrocentesis.
Medications that may be used to relieve pain may include tricyclic antidepressants, muscle relaxants, and prescription-strength painkillers. Botulinum toxin (Botox) can be used alone or in combination with other treatments to relieve the muscle spasm and pain.
There are several types of appliances to treat bruxism. These splints are custom made and help redistribute the force of the teeth while biting. The doctor may fit you with a splint or bite plate. This is a plastic guard that fits over your upper or lower teeth, much like a mouth guard in sports. The splint can help reduce clenching and teeth grinding, especially if worn at night. This will ease muscle tension. The splint should not cause or increase your pain. If it does, do not use it.
Surgery is never the first choice of treatment for TMJ syndrome. Arthrocentesis entails the use of a needle to clean and irrigate the joint. During the procedure, the surgeon may inject a local anesthetic or a steroid into the joint. Arthroscopy surgery is done when there is suspicion of an internal problem with the TMJ. It does require anesthesia and has a high success rate in resolving pain.
Anyone with recurrent or chronic TMJ syndrome is referred for physical therapy. The therapist can help restore joint mobility, increase muscle strength, and relieve pain.
A variety of other treatments are also available for chronic TMJ syndrome and include friction massage, transcutaneous electrical nerve stimulation (TENS), and cognitive behavior therapy.
Follow your doctor’s specific instructions for taking any medication prescribed and for home care with compresses or gentle jaw exercise.
Most people do well with conservative therapy, such as resting the jaw or using a mouth splint. The success of treatment depends on how severe the symptoms are and how well you comply with treatment.
Only about 1% of those with TMJ syndrome require joint replacement surgery.

TMJ disorders affect your temporomandibular joint, which allows your mouth to open and move smoothly. We offer specialized treatment in Los Angeles, CA . The temporomandibular (tem-puh-roe-man-DIB-u-lur) joint (TMJ) acts like a sliding hinge, connecting your jawbone to your skull. You have one joint on each side of your jaw. TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in your jaw joint and in the muscles that control jaw movement. The exact cause of a person’s TMJ disorder is often difficult to determine. Your pain may be due to a combination of factors, such as genetics, arthritis or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth (bruxism), although many people habitually clench or grind their teeth and never develop TMJ disorders. In most cases, the pain and discomfort associated with TMJ disorders is temporary and can be relieved with self-managed care or nonsurgical treatments. Surgery is typically a last resort after conservative measures have failed, but some people with TMJ disorders may benefit from surgical treatments. TMJ disorders can also cause a clicking sound or grating sensation when you open your mouth or chew. But if there’s no pain or limitation of movement associated with your jaw clicking, you probably don’t need treatment for a TMJ disorder. Seek medical attention if you have persistent pain or tenderness in your jaw, or if you can’t open or close your jaw completely. Your doctor, your dentist or a TMJ specialist can discuss possible causes and treatments for your problem.
What are the risk factors for TMJ syndrome? There are several risk factors for TMD: Poor posture in the neck and upper back muscles may lead to neck strain and abnormalities of jaw muscle function. Stress may increase muscle tension and jaw clenching. Women 18-44 years of age have increased risk. Patients with other chronic inflammatory arthritis have increased risk. People with jaw trauma or poorly positioned teeth have increased risk. People who have a genetic predisposition to pain sensitivity and increased stress responses may be more susceptible.
The temporomandibular joint is more commonly referred to as the TMJ joint, but what is TMJ? This joint is actually located at the base of the skull in front of the ear structure and connects the lower jaw (mandible) with the upper jaw (maxilla). Unlike most joints located in the body, the TMJ is unique in its structure, composed of a rounded protrusion of the mandible that sits against an indentation in the skull, and a disc-like structure made of a soft bone called cartilage found in between the two bones (articular disc). These three parts of the TMJ are held together by ligaments originating from different parts of the head and neck to support the jaw and guide its movements. Several muscles are connected to those ligaments, and many aid in the motion of the lower jaw. How Does it Work? The TMJ works in two ways to open your mouth: The first way is like a hinge to simply open and close the mouth, just like a hinge on a door. The second way is a sliding motion called translation, wherein your lower jaw moves down and forward. This motion helps the TMJ to move backward and forward and from side to side for actions such as eating, yawning and singing – some of the most common. What Can Happen to the TMJ? Like any other joint in the body, the TMJ can be fractured, swell and become sore, causing limited movement of the lower jaw and pain radiating to the head and neck area. A fracture to the actual articular disc is rare, but it can be displaced, causing severe pain and swelling. Unlike other joints such as knees and hips, arthritis of the TMJ is very rare, and hard to treat with anti-inflammatory drugs alone. Nonetheless, pain in the TMJ is often temporary, and can be treated with a combination of ice then heat to relieve the sore ligaments and muscles surrounding the joint. The temporomandibular joint (TMJ) is the joint that connects the jaw to the temporal bones of the skull. Temporomandibular joint disorder, known more commonly as TMD, occurs when there are problems with the muscles and jaws in the face. There are many signs and symptoms of TMD. It’s often hard to know for sure if you have TMD, because one or all of these symptoms can also be present for other problems. Your dentist can help make a proper diagnosis. What About Grinding and Clenching? Sometimes, pain in the TMJ can come from the teeth themselves, as opposed to the TMJ and surrounding ligaments.
As a TMJ doctor, Dr. Jacob Elisha delivers a TMJ treatment in Los Angeles for patients who are suffering from extreme pain to help resolve the condition. Because TMJ disorders can be extremely painful, Dr. Jacob Elisha’s first priority is symptom relief. Although these measures won’t permanently cure TMJ, they will alleviate much of the chronic pain associated with the condition. This variety makes diagnosis and treatment challenging. An accurate diagnosis is critical for successful treatment. For instance, patients with a muscle problem that is causing pain will most likely not benefit from surgery on the temporomandibular joint (TMJ). Ask about your doctor’s experience in diagnosing and treating TMJ and facial pain. Most problems, whether muscular or within the joint, get better over time. For this reason, most experts agree that it’s best to use conservative treatment at first. But in some instances, surgery or other procedures, such as injections, may be recommended as a first treatment. Most people with TMD have temporary symptoms that are not serious and do not get worse. They usually can get better with simple treatments done at home. Sometimes symptoms go away without any treatment at all. They also can come back without warning. If you have TMD, your dentist may suggest the treatments listed below. Most dentists agree that these treatments work best in combination. You may not get relief using only one. To begin, Dr. Jacob Elisha will prescribe a pain reliever, anti-inflammatory or muscle relaxant to relieve muscle spasms and joint pain. In some cases, he may also inject a specialized steroid directly into the joints to dramatically reduce pain and inflammation. From there, Dr. Jacob Elisha will prescribe self-care treatments—advising the patient to rest the jaw, eat soft foods, apply ice to the affected area and practice proper posture. Depending on the specifics of your TMJ disorder, he may also recommend physical therapy to improve jaw function.
