What is Bruxism?

Bruxism, commonly known as teeth grinding or jaw clenching, is a condition that affects many people, often without them even realising it. It more commonly occurs during sleep and may contribute to jaw pain, headaches, neck tension, tooth wear, and difficulty chewing or opening the mouth comfortably. While bruxism is often associated with stress, it is usually influenced by a combination of physical, neurological, and lifestyle factors.

The jaw is controlled by a complex group of muscles and joints that work together for speaking, chewing, swallowing, and facial expressions. The temporomandibular joints (TMJ), located just in front of the ears, connect the jaw to the skull and rely on balanced muscle activity to function properly. When excessive clenching or grinding occurs, these muscles and joints can become overloaded and irritated.

Common symptoms of bruxism may include:

• – Jaw pain or tightness
• – Clicking or popping in the jaw
• – Headaches, particularly around the temples
• – Ear pain or a feeling of pressure around the ears
• – Difficulty opening the mouth fully
• – Neck and shoulder tension
• – Tooth sensitivity or wear
• – Symptoms that are worse in the morning

Over time, persistent muscle tension can increase sensitivity in the nervous system, making pain and tightness feel more intense and ongoing. Stress and anxiety are common contributors to bruxism, as the nervous system plays a major role in regulating muscle tension. Poor sleep, fatigue, posture, breathing patterns, and prolonged desk work can also contribute to increased tension around the jaw and neck.

Why Physiotherapy? 

This is where physiotherapy can help. Physiotherapy treatment for bruxism focuses on reducing muscle tension, improving jaw function, calming the nervous system, and addressing contributing factors that may be placing extra stress on the jaw.

A physiotherapist can assess:

• Jaw movement and joint function
• Muscle tightness around the jaw, face, and neck
• Posture and upper body mechanics
• Breathing patterns
• Lifestyle and stress-related contributing factors

Often, jaw pain is closely linked with tension through the neck and upper shoulders, meaning treatment may involve more than just the jaw itself.

Treatment may include:

• – Soft tissue massage and muscle release
• – Joint mobilisation techniques
• – Dry needling where appropriate
• – Jaw mobility and control exercises
• – Postural strengthening exercises
• – Breathing and relaxation techniques
• – Advice around stress management and sleep habits

These treatments aim to reduce muscle overactivity, improve movement, and help retrain the nervous system to reduce protective tension patterns.

Education is also an important part of treatment. Many people are unaware they clench their jaw throughout the day. Physiotherapists can help patients recognise these habits and develop strategies to reduce unnecessary tension. Small changes in posture, work setup, breathing, and stress management can often make a significant difference over time.

Importantly, treatment is individualised. Bruxism can have different causes for different people, and physiotherapy aims to address both the symptoms and the contributing factors behind the condition.

With the right management, many people experience significant improvements in jaw pain, headaches, muscle tension, and overall quality of life. Physiotherapy can help reduce discomfort, restore normal jaw movement, and provide practical strategies to better manage stress and tension long term.
