Chronic recurrent headaches, neck aches, jaw pain and facial pain are a common occurrence for millions of Australians. TMD disorders and TMJ dysfunction result in frequent ear symptoms which can make chewing, speaking or moving the jaw painful or difficult.
Until recently these symptoms appeared unrelated and were frequently undiagnosed or misdiagnosed as a migraine, tension headache, neuritis, neuralgia or stress. Standard treatment remedies for these types of disorders were often unsuccessful.
TMJ Disorders and TMJ Dysfunction
Today it is well recognised that these often unexplained, undiagnosed and therefore untreated symptoms are related to a group of problems called Temporo Mandibular Disorders (TMD) as they affect the Temporo Mandibular joints (TMJ) themselves.
Signs & Symptoms of TMJ Disorders
TMJ Disorder is also known as ‘great impostor’ because this dysfunction has multiple overlapping symptoms that are often mistaken as other medical or dental issues.
We have seen many people suffer most of their lives in pain, not understanding the cause nor realizing that it can be treated.
If you have a TMJ Disorder you may suffer from one or more of the following symptoms:
- Clicking, popping, grating sounds in the ear or joint
- Limited opening of the mouth
- Locked jaw
- Pain or soreness around the jaw joint
- Neck, shoulder or back pain
- Facial pain especially in the temples around the eyes
- Clenching or grinding of the teeth (bruxism)
- Sensitive and sore teeth
- Unexplained loose teeth
- Worn chipping or cracked teeth
- Cracking, chipping or breaking dental restorations
- Ringing in the ears
- Ear congestion or stuffiness
- Numbness, tingling in the fingers or arms
TMD Self – Assessment
If you suffer from jaw pain and/or any of the other TMD symptoms, you may have temporomandibular joint dysfunction (TMD).
Answer Yes or No to the following questions:
- Are you aware of grinding or clenching your teeth?
- Do you wake up with some stiff muscles around your jaws?
- Do you have frequent headaches?
- Does your jaw click, pop, grate, catch or lock when you open your mouth?
- It is difficult or painful to open your mouth widely, to move your jaw from side to side, eat or yawn?
- Are your neck and shoulder muscles stiff, sore or tender to pressure?
- Are your teeth sensitive, loose, broken or worn?
- Do your teeth meet differently from time to time?
- Have you had unexplained toothaches?
- Is it hard to use your front teeth to bite or tear food?
- Does stress make your clenching and pain worse?
- Do you have ringing or buzzing in your ears?
- Do you frequently feel dizzy?
- Do you have trouble sleeping through the night?
- Do you have trouble falling asleep?
- Have you injured your neck, head or jaws?
- The more times you answered ‘Yes’ the more likely it is that you have a TMJ disorder.
Causes of TMJ problems
Temporo mandibular disorders rarely have a single cause. It is important to recognise anything that alters the relationship between the lower jaw (mandible) and the upper jaw (maxilla) has the potential to cause TMD.
Our dentists at Island Dental have been comprehensively trained to assess your unique circumstances in order to find the right treatment for you. Any of the following factors may contribute to TMD:
Sleep Disordered Breathing
Constricted airways, sleep apnoea or sleep disordered breathing can cause TMD. To open your airways to achieve optimal oxygen, your body might unconsciously posture the jaw to give rise to TMD.
Untreated airway constriction from enlarged tonsils or adenoids can cause TMD and have other ill effects due to oxygen deprivation.
A single traumatic event such as whiplash injury could cause TMD in the jaw or skull. These can result from a car accident or a fall/blow to the head that wrenches the jaw out of position at such a force that it causes injury to the hard and soft tissue. If a trauma to the joint causes chronic damage, this can result in a TMD problem at a later time.
Opening too Wide
All joints have limitations to movements and the TMJ is no exception. If you open wide for a long time, or if your mouth is forced open then the ligaments will be torn causing TMD.
Frequently the cause of TMD is structural, biochemical and emotional factors that develop over years and result in TMD. A structural problem is almost always present and leads to over-activation of the jaw, head and neck muscles. Factors related to the teeth and bite are among the most common causes of TMD Disorders.
This is the grinding and clenching of the teeth. It can be while awake but, more often bruxing is done while sleeping. This means you might be waking up with sore, tired jaw muscles and sensitive worn teeth in the morning but may not realise you are a bruxer. The constant grinding of the teeth causes pressure on the TMJ’s and may injure the ligaments. Bruxism is the most common factor found in TMD and is treatable by your dentist.
Malocclusion means ‘bad bite’. When the teeth don’t fit together in harmony with the shape and position of the joints, pressure can be placed on those joints. The chewing muscles suffer from stress and tire, eventually spasming. The spasm causes pain and tissue damage which in turn causes more spasm. This cycle can result in a TMD disorder. Malocclusion may also be produced by: Distorted development of one or both jaws; Underdevelopment of one or both jaws; Airway issues; Loss of teeth without replacement; Over closed bite; High dental restorations; Poor fitting denture or partial denture; Loss of bone in denture patients; Tongue habits; or Orthodontics.
Whilst orthodontics can improve appearance and correct factors leading to TMD some researchers also feel that orthodontic treatment may produce TMJ problems. Proper orthodontic treatment will take into consideration the correct position of the TMJ’s and the skeletal structures as well as the alignment of teeth.
Double jointed people actually suffer ligament laxity. If you are double jointed anywhere in your body there is a strong chance the TMJ will be loose and causing excessive movement. This is a common cause in active young women.
Emotional stress plays an integral role in the development of TMD. Stress increases the severity and duration of bruxism (grinding) whilst asleep. During times of stress many will subconsciously clench and/or grind their teeth more in the daytime too. In times of stress our adaptability goes down. Stress is like throwing petrol onto an existing fire: the fire is a TMJ problem and the petrol is stress. The petrol causes the fire to flair up and burn wildly for a time but the petrol did not produce the fire (or TMJ) it just made it worse.
Various diseases can cause or aggravate TMJ problems. Immune disorders such as rheumatoid arthritis, psoriatic arthritis and systemic Lupus erythematous can produce inflammation in the TMJ. Viral infections such as mononucleosis, mumps, and measles can also cause damage to the surface of the TMJ.
We are just starting to understand the critical role proper nutrition plays in the optimal functioning of our body (including our TMJ), our resistance to stressful situations and our ability to adapt to the challenges within our lives.
In our gravity-based world, our muscles and nerves are designed to keep our head, pelvis and feet level with the ground when standing still or working in balance when under motion. The human body functions best when the skeletal structures are parallel or at right angles to the centre of gravity.
If an area of the system is faulty or injured the body will shift to compensate from its normal balanced posture. This spreads out the forces and allows the injured area to avoid any extra stress on that area. But this compensation now places stress on other, more remote areas to the body and often pain is experienced in these areas. These postural distortions can either contribute to or are the result of TMD problems.
Any activity that causes the head to be held in an unnatural way may intensify TMD problems. Particularly troublesome habits including cradling a telephone between the ear and the shoulders, frequent use of smartphones, carrying a heavy shoulder bag and slumping over a desk to read or type. Playing certain musical instruments and surgery can exacerbate TMD symptoms caused by bad ergonomics.
Occlusal bite disease
This disease often won’t result in pain but does cause worn, chipped or broken teeth, broken fillings. Any changes in the position or shape of one’s skull are all indications of TMD disorder and these patients should address these problems sooner rather than later.
Diagnosis: Using technology
Temporo mandibular disorders and TMJ diagnosis in the past has been tricky and is often misdiagnosed.
To avoid any ‘guesswork’, Island Dental have invested in state of the art technology and bio-instrumentation for fast and accurate computerised diagnostics of TMJ problems and TMD disorders.
This equipment, not available at every dentist, allows our dentists to diagnose, treat and monitor our patients TMD.
These sophisticated instruments have been used by medical TMD specialists for years and are now being used in dentistry to objectively collect data that is proving invaluable in helping many patients that have been previously unable to find relief.
Our TMJ diagnosis technology includes:
- Joint Vibration Analysis
- Jaw Tracking (Electrognathography)
- EMG (Electromyography)
Treating TMJ Disorders
A patient’s TMJ treatment must be tailored to their individual TMJ disorder diagnosis. We recommend that our patient’s first step is to consult a medical doctor to rule out any medical disease that may be causing your symptoms.
Successful treatment for TMD problems will involve a wide range of treatments and a variety of health practitioners since the TMJ and the dental structures are interconnected and interrelated to the overall body alignment and function.
Rebalancing body structures and functions may be appropriate during treatment since most TMJ patients have musculoskeletal problems as well.
TMJ Treatment is divided into three phases.
Phase 1 – Eliminate or reduce pain
The goal of this phase is to reduce and eliminate joint and muscle pain, address structural problems throughout the body and educate the patient as to their role at home. The most common form of treatment at this stage is a splint or orthodontic appliance.
In phase one of treating TMD and TMJ disorders the following steps are normally taken:
- Investigate possible causes of TMD: This may include doing a sleep test to investigate sleep disordered breathing.
- A removable appliance helps to keep the lower jaw in an optimum rest position.Construct a removable appliance: This is done using the relaxed position of the muscles of the head and neck (with help from the TENS) to place the lower jaw in an optimum physiological rest position
- Reduce and eliminate TMJ problems and symptoms
- Correct postural distortions
- Educate the patient as to how they can help themselves. This part of the treatment will usually include exercises, medications, lifestyle changes and stress management.
- There are many types of occlusal splints or orthotics. We will advise you what is the most appropriate splint for your particular needs.
Phase 2 – Correction
This second stage involves correcting body irregularities that are the cause of the patient’s TMD dysfunction.
Phase 3 – Support
The goal of this phase is to maintain support of the TMJ joint by the teeth, ensuring they stay in a pain free position.
Depending on where the pain free position of the jaw lies several different types of therapy are available in Phase 3 including:
- Long term splint use
- Bite adjustment
- Dental reconstruction
- TMJ surgery
Often treatment may include a combination of these therapies.
