Therapeutic Applications
What Can These Injections Help With?
Botulinum toxin injections into the jaw muscles are used strictly for the therapeutic management of the following dental and orofacial conditions.
Bruxism, Daytime Teeth Grinding
Daytime bruxism involves habitual grinding or clenching of the teeth, often linked to stress or postural habits. Therapeutic injections into the masseter (chewing) muscles may help reduce the force of grinding, potentially limiting tooth wear and jaw soreness over time. Results vary and treatment forms part of a broader management plan.
Sleep Bruxism, Nocturnal Grinding
Sleep bruxism is an involuntary grinding or clenching that occurs during sleep, often without the person being aware. It can cause tooth damage, morning jaw ache, and disrupted sleep quality. Therapeutic injections may be considered alongside a custom occlusal night splint as part of a combined management approach.
TMJ Dysfunction, Jaw Muscle Tension
Temporomandibular joint (TMJ) dysfunction can involve overactive jaw muscles contributing to jaw pain, clicking, limited mouth opening, and facial discomfort. Where muscle hyperactivity is identified as a contributing factor, relaxant injections targeting the masseter and temporalis muscles may assist as part of a broader TMJ management plan.
Jaw-Related Headaches
Muscle overactivity in the jaw and temporal region is associated with certain headaches and facial pain patterns. Where jaw muscle tension is identified as a contributing factor following clinical assessment, therapeutic injections may form part of a management strategy discussed with your treating dental or medical team.
⚠ Important Clinical Information
Therapeutic muscle relaxant injections using botulinum toxin are administered by our dentists strictly for the management of dental and orofacial conditions, not for cosmetic purposes. This treatment is not suitable for everyone. A clinical consultation is required before any recommendation is made, and a suitability assessment will be carried out at that appointment.
As with any clinical procedure, individual results vary. The effects of botulinum toxin are temporary and not permanent. Repeat treatments may be needed as part of an ongoing management plan. Our team will always discuss realistic expectations, limitations, and alternative options before proceeding.
If you have been referred by a GP, specialist, or physiotherapist for jaw-related concerns, please bring any relevant referral notes or imaging to your appointment.
Our Approach
What to Expect at Your Appointment
Muscle relaxant injections are only recommended following a thorough assessment. Here is how the process typically works.
Clinical Assessment
Your dentist takes a detailed history of your jaw symptoms, assesses your bite and muscle activity, and may use X-rays or occlusal analysis. The aim is to understand the underlying cause of your symptoms before considering any treatment.
Treatment Discussion
If muscle relaxant injections are clinically appropriate, your dentist explains the procedure, what outcomes may be achievable, the limitations and risks, and any alternative approaches. You have every opportunity to ask questions before making a decision.
Injection Appointment
Injections are administered into the targeted jaw muscles using a fine needle. The procedure typically takes 20–30 minutes and most patients find it well-tolerated. Effects generally develop over one to two weeks and vary in duration between individuals.
Review & Ongoing Management
A follow-up review is scheduled to assess your response to treatment. Injections are not a permanent or standalone solution, they work best as part of a broader management plan that may include splint therapy, physiotherapy, or lifestyle strategies.

Frequently Asked Questions
Are these the same as anti-wrinkle injections?
The active ingredient, botulinum toxin, is the same substance used in some cosmetic anti-wrinkle treatments. However, the therapeutic application for jaw muscle management is a clinically distinct use. At our practice, this medication is used exclusively for dental and orofacial therapeutic indications, administered by a dentist following a proper clinical assessment, never for cosmetic purposes.
How long do the effects last?
The duration of effect varies between individuals, typically ranging from three to six months. Some patients may experience longer or shorter periods of effect. Because the results are not permanent, repeat treatments are usually required as part of an ongoing management plan. Your dentist will advise on a treatment schedule suited to your situation.
Is the procedure painful?
Most patients find the injections well-tolerated. A fine-gauge needle is used and the appointment is relatively quick. You may notice minor discomfort, localised bruising, or temporary tenderness at the injection sites for a short time after. Your dentist will advise you on what to expect and any aftercare.
Can I still wear a night splint if I have these injections?
In many cases, yes. Muscle relaxant injections and a custom occlusal night splint can work well together as complementary management tools. Your dentist will assess whether a combined approach is appropriate for your situation and advise accordingly.
Do I need a referral?
A referral is not required to book a consultation. However, if you have been referred by a GP, specialist, or physiotherapist regarding jaw pain, bruxism, or TMJ symptoms, bringing that referral and any relevant clinical information will help us provide a more complete assessment at your first appointment.
Can I claim on private health insurance?
Coverage for therapeutic muscle relaxant injections varies significantly between health funds and policy levels. We recommend contacting your fund directly before booking to confirm your entitlements. Our reception team can provide the relevant item codes to check with your fund.
Is this treatment right for me?
Only a clinical assessment can determine whether muscle relaxant injections are appropriate for your situation. If you are experiencing jaw pain, teeth grinding, or TMJ-related symptoms, book a consultation and we will assess your condition thoroughly before recommending any course of action. Suitability varies between patients, and this treatment is not appropriate for everyone.
