Face Slimming (Teeth Grinding/ Bruxism)

The Face Slimming Treatment is a great procedure that is commonly requested for many different reasons. Wide faces and grinding of the teeth are commonly due to an enlargement of the Masseter muscles. These muscles, when enlarged, are quite strong and tend to overtly contract even during your sleep. This excessive muscle contraction during sleep causes the teeth to grind against each other leading to headaches, jaw pain and significant teeth injury. In this procedure, anti-wrinkle product is directly injected into the masseter muscles and occasionally combined with anti-wrinkle treatment to the Temple region to help improve more sinister symptoms and headaches.

The Face slimming procedure tends to slim down the face, help alleviate symptoms associated with teeth grinding such as headaches and jaw pain and tend to help people have a significantly improved sleep resulting in a better quality of life.



Treatment takes less than 10 minutes, with minimal pain and no downtime. This is one of the most painless procedures in Aesthetics. Simple and easy treatment to help you look fresh Results lasts 3 to 6 months Prices start from $500, depending on the dose required.

Treatment Considerations

  • Patient Age
  • Size and strength of Masseters 
  • Skin quality
  • Recent treatments and response to previous treatments



A neurotoxin is injected directly into the Masseter muscles in order to minimize the muscles ability to contract. This leads to weakening and shrinkage of these muscles over the next few weeks, which eventually results in a slimming appearance of the face. 

This also helps reduce the symptoms associated with enlarged masseter muscles such as teeth grinding, headaches, lock Jaw syndrome and jaw tenderness. 

Unlike fillers, anti-wrinkle treatments do not show immediate results. Generally, patients tend to notice an obvious improvements in symptoms between 3-7 days after treatment, with a peak effect at 2 to 4 weeks. 

The cosmetic face slimming results can generally be seen 4 to 6 weeks after treatment.  

Generally 3 to 6 months. Approximately just over 60% of patient will retain neurotoxin effects at the 4 months mark post treatment. Depending on genetics and lifestyle, some patients only retain effects for up to 8 weeks (those who are extremely physically active tends to metabolize the product faster and have shorter lasting results). 

The masster muscles generally require more frequent treatments to help treat Bruxism disorders, locked jaw syndrome and headaches, with a decrease in frequency over time



Mild Swelling at injection site


Infection- very rare

Asymmetry, one sides may be more responsive to treatment than the other

Headaches may occur, more likely to occur on first time treatment

Less than 1% chance that some of the neurotoxin can cause temporary paralysis of one of the smile muscles. This may temporarily lead to an asymmetrical smile which self resolves over time. 

Some patients may experience some difficulty chewing hard food products, as this is due to weakening of one of the stronger muscles associated with chewing

Most practitioners and patients prefer to have some form of pain relief. There are multiple options available for your convenience;

  • Initially, a topical numbing agent such as emla cream or lmx, is applied to the area of treatment. Common additional forms of pain relief:
  • Local anaesthesia using a nerve block is a fantastic method to achieve almost no pain at all, however this does vary based on individual. This is quite similar and sometimes used interchangeably with the term dental block. Most dermal fillers also contain local anaesthesia and hence any pain experienced during treatment generally tends to improve throughout
  • Laughing gas (also known as happy gas or Nitros oxide) is also available.
  • Applying ice to the area prior to treatment can also help reduce the pain, and applying ice after the procedure also helps reduce the swelling.
