Teeth Grinding (Bruxism), masseter reduction and slimming the lower face.

Muscle Relaxant Injections

The use of muscle relaxant injections (or anti-wrinkle injections) is not just reserved for the relaxation of lines of facial expression and wrinkles.

Muscle relaxant injections are a simple and effective treatment involving the injection of wrinkle relaxers into the large masseter muscles of the jaw. It is a popular procedure used to reduce the size of the masseter muscles and is an extremely effective treatment for teeth grinding or bruxism.

It takes just 10-15 minutes to relax the muscles – with results that can last up to 5 months before your top-up is due.

It is also especially effective for Jawline slimming (masseter reduction) and achieving a V shaped face.

The effects of Bruxism

People who suffer from bruxism often report daily headaches, TMJ pain, ear and facial pain, worn down teeth and dental problems. They suffer from daily pain and discomfort which has previously only been treated with special splints and physiotherapy.

In addition, the overuse of the masseter muscles from chronic grinding results in hypertrophy of the muscles (enlargement of the muscle) which causes cosmetic deformities and an enlarged, square shape to the lower face which is often asymmetrical.

The treatment can transform your face completely; many people go from having a square and masculine jaw to a narrow and oval face in a matter of weeks.

Frequently Asked Questions

+What is the treatment actually like, how many units do I need?

The dose should be decided by the physician based on the strength of the Masseter muscle immediately prior to injection. Of course, it will differ from person to person, but typically I start with a lower dose and recall the patient in two weeks to potentially add five to ten units more each side. An average dose might be around the 25-50 unit mark.

+Is it painful?

Maybe a 3/10 on the pain scale. Only small insulin needles are used for this procedure.

+Does it slim the jawline?

If you repeatedly treat an enlarged Masseter (from grinding), the muscle will shrink in size. This causes the jaw slimming effect.

+Are there any side effects?

Some common side effects are pain and bruising at the injection sites that last for a few days. Uncommon side effects can be issues relating to the smile’s appearance. If the product spreads to muscles involved in smile formation, it can change the way you look.

+How long do the results last?

Effects typically last 4 – 6 months depending on the dose used. We would suggest using a splint in addition to regular top ups.

+What is the cost?

Treatment starts from $150, depending on the dose required. On average most pay up to $300.

+What does the treatment involve?

A consultation with our doctors/nurses is essential prior to having any treatment. A treatment plan will be arranged to address individual concerns and desired aesthetic outcome.

Muscle relaxant injections (the same product used as anti-wrinkle injections) is injected into the masseters on each side of the face and spread out at multiple points within the muscle to produce jaw reduction results. The amount of wrinkle relaxer used does vary but in general much larger amounts are needed when compared with treatment of wrinkles.

Facial slimming and a jawline reduction effect is seen at any time between 2 to 8 weeks. Most patients report a symptomatic relief of their facial pain and headaches within 2 weeks. Full aftercare instructions are provided following each appointment.

+Are there any risks of treatment?

With any medical procedure there are always risks involved and your doctor/nurses will discuss all risks and contraindications prior to performing any procedure.

The procedure is highly effective, with minimal or no pain and minimal downtime. Minor side effects such as bruising and swelling to the injection points may be noted.

A less common side effect is over treatment of the masseter muscles resulting in problems with chewing. This is minimised by correct dosing and placement of the muscle relaxing injections. A rare side effect is an asymmetrical smile due to product diffusion to neighbouring muscles.

Muscle relaxant injections cannot be given in people with underlying neurological conditions such as Myasthena gravis and in pregnant or breastfeeding women.
