Consultations for the Management of Bruxism

What is Bruxism?

Bruxism is a condition where a person clenches or grinds their teeth, often during sleep and sometimes during the day without realising it. Over time, this can lead to jaw muscle tension, headaches, tooth wear, jaw pain, and disturbed sleep.

Many people are unaware they have bruxism until symptoms develop or their dentist notices signs of tooth grinding.

Bruxism is a recognised medical condition, not simply a nervous habit.

It has documented causes, clear diagnostic criteria, and a range of evidence-based treatments that extend well beyond telling someone to relax! Night guards, stress reduction, and behavioural therapy all have a role in management. But for moderate to severe cases, therapeutic injectables have become one of the most clinically substantiated interventions available, and that changes where some patients end up seeking care. In doctor-led clinics where therapeutic injectables are administered under strict medical guidelines, jaw clenching and teeth grinding treatment looks quite different from what most patients expect.

How Can Bruxism Be Treated?

Van Zandijcke et al. (1990) first reported the therapeutic effect of botulinum toxin (BoNTA) in the treatment of bruxism. These TGA-approved prescription treatments may be used to help reduce the activity of the jaw and temple muscles involved in clenching and grinding. This may help relieve muscle tension and reduce associated symptoms such as jaw pain and headaches.

Treatment is provided only after a medical consultation to assess suitability, explain potential risks and side effects, and discuss expected outcomes. This treatment requires precise injection techniques and a sound knowledge of facial anatomy to avoid complications. Results vary between individuals and ongoing treatments may be required.

This treatment is aimed at symptom control and does not cure the underlying cause of bruxism. You should continue to use treatments recommended by your dentist or other medical specialists.

Temporomandibular Joint (TMJ) Dysfunction

Temporomandibular Joint Dysfunction (TMD) refers to a group of conditions affecting the jaw joint, surrounding muscles, and associated structures. The temporomandibular joint connects the mandible to the temporal bone and is responsible for essential functions such as chewing, speaking, and facial expression.

TMD is typically multifactorial. Common contributing factors include bruxism (teeth grinding/clenching), muscular overactivity, joint disc displacement, and psychosocial stress. In some patients, occlusal factors or prior trauma may also play a role.

Clinical features vary but commonly include:

  • Jaw pain or tenderness

  • Clicking, popping with jaw movement

  • Reduced range of motion or locking

  • Headaches, particularly temporal

  • Referred pain to the ear, neck, or shoulders

TMJ Dysfunction often involves a combination of:

  • Myofascial pain from masticatory muscle hyperactivity

  • Internal derangement (e.g., disc displacement)

  • Low-grade joint inflammation

In selected cases, targeted interventions such as botulinum toxin injections into hyperactive masticatory muscles may be considered to reduce muscle overactivity and associated symptoms, and can form a part of a treatment plan - but it may not resolve it.

Frequently Asked Questions

  • Bruxism means clenching or grinding your teeth, often during sleep.

  • You might notice jaw pain, tightness, headaches, worn teeth, or wake up with a sore face. Sometimes a partner hears grinding at night.

  • It can be linked to stress, poor sleep, or how your teeth and muscles work together. Often, there isn’t just one cause.

  • A doctor will ask about your symptoms, examine your jaw and teeth, and decide if anything else needs to be looked at.

    Often your dentist is the first one to mention bruxism to you.

  • Simple options include mouth guards (splints), stress management, and jaw exercises. Treatment depends on your specific situation.

  • In some cases, muscle-relaxing injections can help reduce clenching. This is considered if other treatments haven’t helped enough.

  • The goal is to reduce pain, tension, and grinding. Results vary, and it may not completely stop the habit.

  • Possible effects include mild discomfort, temporary weakness when chewing, or changes in muscle shape. These will be explained in detail before treatment.

  • Yes. You’ll need a consultation with Dr Raj to make sure the treatment is suitable for you.

  • Often yes. A combination approach (like a splint plus other therapies) usually works best.

  • The cost of treatment depends on the muscles treated and the amount of product required. As this is a prescription-only medical treatment, pricing is provided after a thorough consultation.

    There is an upside - as larger doses of medication are required to treat the involved muscles than used commonly to treat muscles of facial expression, patients often report effects that last well beyond the average of 3-4 months, as seen when treating wrinkles. Some of our patients only require treatment twice per year.
