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 prescription-only 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.

ADHD, ADHD medication and jaw clenching

ADHD itself appears to be associated with bruxism.

A systematic review in children and adolescents found that those with ADHD had almost three times the odds of bruxism compared with those without ADHD. Importantly, the available research is predominantly in younger populations, so that figure should not simply be applied to adults.

Medication adds another consideration.

Several medications used to treat ADHD have been associated with clenching or grinding in susceptible patients. The evidence is strongest for some medicines and considerably weaker for others.

This means that if you have ADHD and clench your jaw, it should not automatically be assumed that your medication is responsible. The activity may have been present before treatment, and the medication may have made an existing tendency more noticeable.

Sleep, stress and other factors may be involved at the same time.

This is increasingly relevant in Australia. More than 4.6 million ADHD-related prescriptions were dispensed to just under 600,000 people in 2023–24, with psychostimulants accounting for 87% of those prescriptions.

What happens at a Cosmenon Bruxism Consultation?

We start with the history rather than the injection.

We look at what you are actually experiencing, whether the activity seems predominantly awake or sleep-related, when it began, what symptoms it produces and what might be contributing to it.

If you have ADHD, we can look at the relationship between your symptoms and your medication history without assuming that medication is necessarily responsible.

We assess the masseter and other relevant masticatory muscles and consider whether the presentation appears predominantly muscular, dental, joint-related, sleep-related or mixed. Sometimes reducing muscle activity is a reasonable treatment.
