What Causes The TMJ Syndrome and TMJ Pain?

TMJ is a Tamporomandibular joint and any problem in the functioning of the joint is called the TMJ syndrome. There might be a variety of reasons for the causes of TMJ pain but it is important to remember that all reasons lead to one logical conclusion i.e. a lot of pain. So what exactly is TMJ? The Tamporomandibular joint is a very complex one and even the slightest of issues can cause severe pain in the jaw.

 

TMJ Diagnosis

TMJ diagnosis is not simple since its symptoms are shared with other conditions. The symptoms vary among patients from ringing ear pain to tension headaches. It could therefore take months and a couple of doctors before you get an accurate diagnosis on your condition. However, a dentist is in the best place to assist TMJ patients since the joint is in the facial area. If you suspect that you may be suffering from any TMJ complication, it is recommended that you visit your dentist.

The diagnosis of this disorder is initiated with an oral health check-up. This is a thorough procedure which will examine the jaw area for any tenderness or swelling. Jaw joints are also assessed to identify if there is any clicking and if their movement is in order. A clench test is may also be conducted. This is done to identify the nature of the pain you are undergoing. The clench test reveals the teeth’s structure and a bad bite is usually a result of pain either in the jaw or teeth.

X-rays can also be taken to carry out a proper analysis of the jaw structure. The X-ray and teeth impressions are both used to create a jaw/bite connection and hence identify the state of the TMJ. A T-Scan is used to further establish the exact disorder present. Depending on the extent of your condition your dentist may require you to take an MRI or CT scan among other analysis tests on your jaw joint. It is important to ensure that you visit your dentist regularly, and especially when you constantly clench your teeth or feel jaw pains. TMJ can be very painful and uncomfortable, so early treatment is advised in order to treat or cure TMJ.

TMJ Causes

Temporomandibular Joint Disorder is a condition that affects the face, head, jaw, neck, jaw nerves, and muscles as well as the temporomandibular joint itself. The root cause of this disorder is excess strain on the jaw joint brought about by a variety of reasons. When treating temporomandibular joint disorder, it is important to know what the exact causes are in order to treat the condition effectively. Patients tend to self medicate themselves with painkillers and other treatment therapies letting the condition control their lives for years. It is therefore important to seek medical advice when experiencing TMJ pain. There are a variety of causes for TMJ disorders and these may come from lifestyle choices, diseases, or even accidents.

TMJ dysfunction can cause neck pain, headaches, tinnitus, as well as numerous related symptoms. The most common is trauma, micro trauma, stress, nutrition, postural problems, or hormonal variations. Any injury to the jaw, muscles, or joints of the neck and head – such as a whiplash or heavy blow – may cause TMJ. Other probable causes can be clenching or grinding of the teeth that put pressure on the joint, soft disc, or cushion dislocation between the sockets and ball. Also the presence of rheumatoid arthritis or osteoarthritis in the joint as well as stress causes a person to tighten their jaw and facial muscles or clench their teeth.

TMJ or TMJ dysfunction often compromises the flexibility of the jaw and can cause TMJ pain at rest or during common movements such as during talking, yawning, or chewing. The TMJ anatomy is made up of the hinge of the joint that is attached to the lower jaw known as the mandible, and to the temporal skull bone that is right in front of each ear on both sides of the head. These joints are extremely malleable and allow for the jaw to smoothly move from side to side as well as up and down.

The American Dental Association points to various causes for TMJ pain with the causes depending on each individual’s case.

The Most Common TMJ Causes

Trauma: 

Trauma to the head, neck, face and jaw can lead to a temporomandibular fracture. This trauma can come about from a punch to the face, especially to the jaw area, a fall, or an accident where the impact was on the head. Other causes include injuries to the chin, whiplash, or contact sports related injuries. Internal Derangement is common with injuries and occurs when the TMJ jaw is dislodged or dislocated. This could be caused by a number of reasons such as a fight or even an accident.

Bruxism:

Major causes of the TMJ syndrome include bruxism and clenching.  Both of them are major contributors usually when a person gets hogged with the Tamporomandibularjoint pain. Bruxism is the habit of grinding your teeth. This can result in inflammation, muscle spasms, and can wear down the teeth. The constant grinding of teeth can cause inflammation around the joint which can cause hindrance in the movement of the joint. Simply grinding food with one’s teeth doesn’t cause bruxism, rather it’s the grinding using misaligned teeth or having two mismatched teeth, that cause the inflammation. Teeth grinding begins as a small habit but can slowly become a consistent occurrence that gets out of control. Most people who grind their teeth have a hard time stopping and even find themselves grinding their teeth as they sleep.

Clenching:

Clenching items with your teeth is another habit that can lead to temporomandibular joint disorder and cause TMJ pain. Clenching is due to continually clenching your teeth together, which overworks the joint and as a result, one starts feeling pain in the joint after a certain period of time. Clenching could be in the form of chewing gum, biting fingernails, pencils and pens. Clenching the jaw repeatedly can destroy teeth, dislodge the jaw bone and cause pain as well. However, dislodged teeth from bruxism and clenching can be treated using braces.

Arthritis:

TMJ Arthritis is characterised by inflammatory and degenerative joints and is one of the causes of TMJ. There are two types of arthritic changes which may cause the TMJ syndrome. Osteoarthritis is one type of arthritis which can cause a lot of pain in the joint and can seriously dent your dental and oral health. It is usually caused due to the breakdown of the Tamporomandibular joint as a result of normal aging and thus, it is one of the major causes of TMJ in senior citizens. Rheumatoid arthritis is the other type of arthritis which is also a major cause for TMJ. It is one of the major reasons for TMJ syndrome in children as rheumatoid arthritis causes inflammation around the TMJ joint, which restricts movement of the joint, resulting in severe pain. Rheumatoid and Osteoarthritis are both bone ailments which may also lead to arthritis. Osteoarthritis is usually found in aged bones which tend to degenerate leading to cartilage loss and a lack of new bone formation. Rheumatoid arthritis, especially in young children, can also lead to bone deformities and inflammation in a variety of joints.

Drug Abuse:

Drugs such as cocaine involve a lot mouth activity such as clenching and grinding and hence lead to a TMJ problem.

Improper Posture:

People are always advised to maintain a good posture by sitting upright without slouching or hunching the back. Unfortunately not many people follow this advice. A bad posture places a lot of pressure on the spine and hence the temporomandibular joint causing TMJ pain. Constant slouching shifts the lower jaws forward and as result your teeth alignment becomes unproportional.

Taking Oversized Bites:

Though taken lightly, taking large bites of food stresses the jaw muscles and can be a contributor to TMJ conditions. It is important that you do not stress your mouth and instead only eat what can comfortably fit. Another possible cause, although much less common, results from excessively chewing gum or hard, sticky candies.

 

TMJ Anatomy:

Another major cause of TMJ and TMJ pain is none other than the anatomical features of the person. Some people are born with a natural problem like the presence of scar tissue in and around the TMJ area, which can create serious problems for them while biting or chewing anything. This would put a lot of pressure on the joint, and as a result, the person with such an anatomical problem would suffer from the TMJ syndrome.

There are a number of other causes which can cause TMJ such as certain diseases which can cause inflammation around the joint, while low-level infections and dislocation of the joint are other major causes. Someone can also have myofacial pain which brings about grave pain and distress in the jaw muscles and nerves. It’s important to find out the cause for TMJ because this will determine the kind of treatment the person will undergo. The symptoms of TMJ make the cause often very clear and thus, it becomes easier for the dentist to decide a plan of action on how to tackle the TMJ syndrome.
