Most people open their mouth to chew, speak and swallow without any thought or difficulty … thanks to the complex and unique temporomandibular joint (TMJ) anatomy. These joints allow you to push your jaw back, slide it forward and open and close your mouth. But that’s not all; the TMJ also moves your jaw side to side. And all of these movements are produced by a group of muscles.
However, complications can arise with a joint this multifaceted, and according to the National Institutes of Dental Craniofacial Research (NIDCR), there are three common TMJ disorders people often experience.
Muscle Complications
The muscles responsible for moving your jaw can handle a lot of chewing and talking, but overuse can lead to tightness and pain. Opening

Arthritis
Arthritis, can affect any of your joints, and the TMJ is no exception. Many people over the age of 50 deal with osteoarthritis, which causes the deterioration of cartilage in various joints. This can affect the TMJ because the cartilage is not as strong, but it mostly occurs when the disc is missing or deformed. Rheumatoid arthritis is an autoimmune disease that causes pain and inflammation in many joints, but merckmanuals.com reports that only 17 percent of people with RA have their TMJ affected as a secondary condition.
Treatment for osteoarthritis of the TMJ involves resting the jaw, analgesics for pain, and possibly a splint to relieve muscle tightness. Symptoms usually subside in about 6 months, but your ability to open your mouth may be limited. When rheumatoid arthritis affects your TMJ, you will be treated with the same RA drugs used for any joint, along with NSAIDs for pain. Keeping the TMJ mobile is important; therefore, your doctor may recommend physical therapy and have your dentist make a splint to relieve muscle tightness. In rare cases, surgery may be needed to replace the
Reoccurring joint dislocations are common, and joints such as the shoulder, patella, and temporomandibular joint dislocate frequently. Chronic joint and limb pain is common amongst individuals with Hypermobile type EDS.
Dental assistant mostly experience right-sided neck and shoulder pain, also hand and finger pain that is worst in the first and second fingers. If it doesn’t get taken care of immediately, this pain could lead to muscle imbalances, ischemia, nerve compression, or disc degeneration. Structures in the musculoskeletal system can be affected by long-term wear and tear.
Rheumatoid arthritis is not curable. Medications will be recommended to relieve pain, reduce inflammation, slow the progression of RA, and save joints and tissues from permanent damage (Rheumatoid Arthritis, 2017). The most common medications are nonsteroidal anti-inflammatory drugs (NSAID) and disease-modifying antirheumatic drugs (DMARD), e.t.c. When having RA, it is important to exercise regularly, apply heat or cold to affected areas, relax, and eat healthy. Physical therapy is usually part of treatment for RA. The goal is to stimulate the bones, muscles, and joints to give them strength and flexibility (Physical Therapy for RA, n.d.). Foods that have lots of omega-3 (fish, chia seeds, flax seeds, and walnuts), high antioxidants like vitamin A, E, and C (berries, dark chocolate, spinach, kidney beans, pecans, and artichokes), and lots of fiber can help reduce inflammation (Foods that fight RA inflammation,
Pivot Joint This type of joint is also known as a rotary joint and allows only one type of movement, rotational movement which occurs when bone rotates on or around another bone, an example of this type of joint includes the joint of the first and second vertebrae of the neck that allows the head to move back and forth, the joint in the wrist which allows the palm to be turned facing upwards and facing downwards, this type of joint is incredibly important because it allows the bones to move freely while rotating, without this type of joint we wouldn’t be able move our head or our hands and wrists. The bones in a pivot joint are connected by ligaments to allow flexible side to side movement. Different types of bones are connected in a joint, for example, irregular bones like the vertebra and the skull is connected in a pivot joint. Hinge Joint
Osteoarthritis is the most common type of arthritis, it affects millions of people around the world. It is also known as Degenerative Joint Disease or Degenerative Arthritis or Wear & Tear Arthritis. Osteoarthritis occurs when the protective cartilage in the joints wear down over time. While osteoarthritis can affect any joint in your body, it more often is seen in the knees, hips, hands, neck, and lower back it worsens as you grow older and has no known cure.
It is still unknown what the cause of Rheumatoid Arthritis is but there are some theories that have not been proven. The oldest theory states that viruses and bacteria are the cause of Rheumatoid Arthritis. Now with all the research being done, scientists believe that Rheumatoid Arthritis is hereditary. Specific genes have been found to make people more likely to get Rheumatoid Arthritis. Some scientists also think that some environmental factors and infections might cause the immune system to attack. Contributing factors are smoking and being exposed to silica metal. So although the exact causes are unknown, the result is that the immune system is ready to make the joins and tissues inflamed by activating immune cells.
Once you reach this stage, you may need to have surgery to save your teeth. If not treated, the infection begins destroying the bone around the teeth. If the bones, tissue and gums supporting your teeth are destroyed, the teeth may begin to shift, loosen and/or fall out. Although the majority of people do not realize they have gingivitis, now that the disease has progressed, the symptoms are more evident. Symptoms include: Pain upon the chewing surface.
“Always remember to be an internist, my dear.” This was an invaluable piece of feedback I received on a rheumatology rotation in my first year of internal medicine residency. Truly, I have never learned so much about medicine as I did during this first rotation in rheumatology. I became fascinated by the subtle presentations and cases that posed a diagnostic challenge to multiple subspecialties. I have been inspired by rheumatology as a field where multisystem disease is encountered on a daily basis and rheumatologists must use both general medicine and subspecialty skillsets to diagnose and treat patients. The academic challenges in rheumatology initially attracted me to the field however my subsequent experiences with patients, mentors, and research have made me passionate about pursuing rheumatology as my specialty.
Hi I’m Mallorie, I’m 31 years old and this is My Arthritis Story. In the winter of 1995 at the age of 10 I came down with one of the many cases of strep throat. I started getting fevers and complaining of joint pain on a regular basis.

Your bones meet at joints, which have diverse limits for development. The most versatile joints are lined with a smooth tissue called ligament and contain liquid to anticipate bone-on-bone friction. Joint issue are the main kind of skeletal framework infection.
(Tacoma, WA) According to the National Institute of Dental and Craniofacial Research, between five and 12 percent of the population suffers from a condition known as TMJD or temporomandibular joint and muscle disease. Young children are more likely to be affected as are women. Pain is often reported with TMJD as is popping noises when the joint is moved. Patients also frequently report they have trouble chewing and sensitive teeth tend to be an issue. Thankfully, a Tacoma dentist can be of
Almost everyone develops osteoarthrits as they age, some get it while in their fifties and in others it does not appear until their eighties. Osteoarthritis is the most common form that affects older people; this form of the disease wears down the cartilage mostly through overuse and injury but there are other causes. This specific form of the disease causes the cartilage to break down and the bones to rub against each other. Deformity and swelling occurs because knobs of hardened bits of cartilage develop in the joint. It forms especially if a joint has been injured many times.
By repeatedly engaging in this behavior, along with having to reach for dental instruments and attempting to keep the patient in a comfortable position, dentists are at a higher risk of musculoskeletal pain or injury1. As a result of experiencing musculoskeletal pain, some outcomes might include an increase in fatigue and discomfort and/or a decrease in fine motor skills thus, limiting the number of patients that can be seen by the dentist1. According to a review by Banerjee et al., researchers found through a survey directed at dental practitioners, that discomfort in those surveyed occurred at a rate of 69.5% in the wrist or hands, 68.5% in the neck, 67.4% in the upper back, 56.8% in the lower back, and 60% in the
An individual that suffers from an articulation disorder can delete sounds, add sounds, have distorted sounds and substitute sounds. Articulation is considered to be the process of the movement of muscles in your mouth. The most important articulators include: jaw, lips, teeth, tongue, velum, alveolar ridge, and hard/soft palate. These articulators are used when producing a sound or when having a conversation. An articulation disorder can be caused by illness, developmental disorders such as autism, neurological disorders, hearing loss, and genetic syndromes such as Down
