Temporomandibular Joint Disorder

The temporomandibular joint (TMJ) is a small but complex joint located in front of the ear, where the lower jaw connects to the skull. The joint allows for the complex movements needed for chewing, speaking, swallowing and facial expressions.

When the joint, its cushioning disc or the surrounding muscles and ligaments become irritated, strained or damaged, this can lead to temporomandibular joint disorder (TMD). TMD can affect the jaw joints, muscles and surrounding structures and may cause symptoms ranging from mild discomfort to persistent pain and restricted movement.

Dr Devin Vaghela has a particular interest in TMD, occlusion, functional corrections and jaw-joint problems. He takes a comprehensive approach to understanding how the teeth, bite, muscles and jaw joints work together, helping to identify the factors that may be contributing to your symptoms.

TMJ disorders can range from mild, temporary problems to more persistent conditions requiring assessment and treatment. Temporomandibular joint dysfunction can sometimes improve with lifestyle and behavioural changes, particularly where symptoms are associated with muscle tension, jaw clenching or teeth grinding.

More complex conditions can involve inflammation within the joint, displacement of the cushioning disc, changes to the joint surfaces or strain affecting the muscles responsible for controlling the jaw.

Jaw clenching and teeth grinding can place significant pressure on the temporomandibular joints and surrounding muscles. Other habits, including excessive chewing, nail-biting or regularly eating very hard or chewy foods, can also contribute to jaw strain.

External trauma, such as an injury to the jaw or face, can damage the joint or surrounding structures. Inflammation associated with conditions such as rheumatoid arthritis or osteoarthritis may also affect the temporomandibular joints.

This can lead to a range of symptoms, including:

• Jaw pain, tenderness and stiffness
• Facial, neck or shoulder pain
• Restricted movement or difficulty opening the mouth fully
• Headaches and facial pain
• Earache, pressure around the ears or tinnitus
• Clicking, popping or grinding sounds when moving the jaw
• Jaw locking or difficulty moving the jaw normally
• Changes in the way the upper and lower teeth meet when biting

An accurate assessment of TMJ disorder is essential to understand the possible causes of your symptoms and develop an appropriate treatment plan.

Following a thorough evaluation, Dr Vaghela will guide you through the treatment options available, ensuring that you understand the potential benefits, limitations and expected recovery associated with any recommended treatment.

Treatment for TMD will depend on the underlying cause and severity of your symptoms. Surgery is generally considered only when more conservative approaches have not provided sufficient relief or where there is significant structural damage to the joint. Whenever appropriate, we aim to use conservative and minimally invasive approaches first.

Treatment options may include:

• Lifestyle changes: Relaxation techniques, dietary adjustments and specific jaw exercises may help reduce strain on the joints and muscles and improve jaw function.
• Behavioural adjustments: Avoiding habits such as clenching, grinding, nail-biting and excessive chewing can help reduce pressure on the temporomandibular joints.
• Bite assessment and management: An assessment of the way the teeth meet can help identify functional factors that may be contributing to symptoms. Where appropriate, treatment can be considered to improve bite function and balance.
• Nightguards and splints: A custom-fitted clear plastic appliance, generally worn at night, may be recommended to protect the teeth from grinding and help reduce pressure on the jaw muscles and joints.
• Medication: In some cases, medication may form part of a wider treatment plan to help manage pain, inflammation or muscle tension.

For more advanced cases, further treatment may be considered:

• Minimally invasive procedures: Depending on the condition affecting the joint, treatments such as joint lavage, injections or other minimally invasive procedures may be considered.
• Open joint surgery: Surgical treatment is generally reserved for severe cases involving significant joint damage, deterioration or other structural problems. In selected circumstances, joint replacement may be considered.

The most appropriate treatment will depend on your individual diagnosis and symptoms. Dr Vaghela will discuss the available options with you so that you can make an informed decision about your care.

If you are experiencing persistent jaw pain, clicking, restricted movement or other symptoms associated with TMD, you can self-refer for a consultation at The Bristol Dental Practice. Alternatively, you can ask your GP or dentist to refer you.

Dr Vaghela can assess your symptoms and help determine whether they are associated with the temporomandibular joints, jaw muscles, your bite or other dental factors. Where further investigation or specialist treatment is required, this can be discussed as part of your treatment plan.

Seeking an assessment can help you understand the underlying cause of your symptoms and the treatment options available, without having to wait for symptoms to become more severe or disruptive to your everyday life.
