Jawline Slimming / Teeth Grinding

jawline slimming patient

Do you have a square lower face and jawline? Or have you noticed that you constantly clench or grind your teeth, or seem to get frequent headaches? If so, you may have an overly active bite muscle (Masseter) causing bruxism. Not only are there cosmetic implications when considering this muscle, but there can also be a real impact to your dental health due to unnecessary strain.
Using Anti Wrinkle injections, you can slim your lower face, and find relief from your constant clenching and teeth grinding, with only a few small injections that takes minutes, all with no downtime.

This is a popular cosmetic treatment with Asian patients who desire a slimmer and more delicate jawline, and can also be done in men to alleviate the symptoms of bruxism.

How Does Jawline Slimming Work?

The anti wrinkle injections temporarily interrupt the communication between nerves and the bite muscle. The result is that the muscle loses strength, and then slims over 4-6 weeks. Patients experience a reduction in their teeth grinding within 1-2 weeks, while the slimming effect occurs gradually over a month.

Jawline Slimming uses Anti Wrinkle injections to weaken and shrink the bite muscles. Following a thorough consultation and assessment, Dr Aaron will advise on the amount of Jawline Slimming treatment required to achieve your goals. The procedure takes approximately 5 minutes, and there is only mild discomfort. A very small needle is used to inject the product into the bite muscles, and some people report a slight stinging sensation as the product is being injected. There tends to be no discomoft or pain after the injection. The results for teeth grinding will be apparent within 2 weeks. The jaw slimming appearance takes between 2 and 8 weeks. Dr Aaron does not routinely follow up his Jaw Slimming patients, however there is the option of an 8 week review appointment to assess the outcome of the treatment, and adjust the dose as necessary.

Yes. Jawline Slimming treatment is safe. As with any medical procedure, there are still risks and side effects. Dr Aaron will discuss these in depth with you during your consultation. Side effects are uncommon, but include:

  • Bruising.
  • Itching.
Rare risks include:
  • Smile asymmetry.
  • Minor weakness when chewing.
The side effects of Jawline Slimming are self-limiting, and will resolve on their own. This treatment is strictly not performed in people who are pregnant, breastfeeding, having IVF treatment, or planning any of the aforementioned; or in those with underlying neuromuscular conditions including Myaesthenia Gravis and Eaton Lambert syndrome.

Following the initial treatment, a repeat dose may be required after 4-8 weeks depending on the initial result. This is because each patient has different sized bote muscles, with different strength. Results last 6-12 months, with subsequent treatments having a better effect.

There are a few steps to take before your Jawline Slimming treatment to ensure the best outcome, and the lowest risk of side effects. They include:

  • Ceasing all anti-inflammatories, aspirin, herbal supplements, fish oil, krill oil, glucosamine and vitamin E 1 week before your treatment (Unless you have been advised to take these by a Medical Practitioner).
  • Avoiding alcohol for 2 days before your treatment.
If you do not adhere to the above your treatment may still proceed, but you will have a higher risk of side effects.

Following your treatment you will be provided with full aftercare instructions. You will be able to resume most normal activity immediately. The most important instructions are the following:

  • Apply an ice pack gently for any discomfort.
  • Do not lie down for 4 hours.
  • Do not touch the treated area for 6 hours.
  • Avoid alcohol for 24 hours.
