Teeth grinding & clenching

Teeth grinding and jaw clenching can be quickly and conveniently treated using no-downtime muscle relaxing injections to the temporalis and masseter muscles.

In some people, these muscles are too strong and overactive causing chronic clenching and grinding (known as bruxism). By treating them with muscle-relaxant injections, they undergo a controlled weakening, reducing their activity and improving clenching and grinding symptoms.


Treatment takes 10-20 mins. No downtime.

Minimal discomfort. Numbing available.

Result within 1-2 weeks.

To maintain effect, revisit every 6-9 months.

What the treatment can do

Struggling with constant jaw clenching and pain? Wearing your teeth down from grinding day or night?

Teeth grinding, also known as bruxism, is a common condition, with some studies showing that over 10% of us clench our jaws and grind our teeth.

Fortunately, there are a number of effective ways to treat bruxism, one of which is teeth grinding injections. Teeth grinding injections are one of our most common treatments here at Cosmetic Connection. They are a simple procedure that involves injections of a muscle-relaxant to the masseter muscles along the jawline and the temporalis muscles in the temples. They cause a temporary, controlled relaxation of the muscles, reducing their strength and activity, and reducing grinding, clenching and the associated pain.

The team at Cosmetic Connection are here to help you with your teeth grinding. We’ve treated countless people who suffer with bruxism with success. The treatment is simple, safe and has minimal discomfort and no downtime. During your comprehensive consultation, we will assess your suitability for teeth grinding injections to treat your bruxism, and will be able to advise on other treatment options that can be used in conjunction to ensure you get the most relief.


Injections for teeth grinding have a number of benefits, including:

  • Treats teeth grinding and jaw clenching (bruxism)
  • Reduces jaw pain from clenching
  • Protects your teeth from damage due to grinding and gnashing
  • Slims prominent masseter muscles, giving the lower face a more balanced appearance
  • Improve jawline symmetry

Teeth grinding injections are a non-invasive, no downtime procedure that take just a few minutes to perform.


How to prepare for teeth grinding injections:

  • Remove all makeup immediately before your appointment
  • Avoid consuming excessive alcohol within 24 hours of your appointment
  • Refrain from intense exercise immediately before your appointment

Teeth grinding injection aftercare:

  • You may experience mild tenderness in the treated area for a few days
  • Avoid makeup, excessive alcohol and intense exercise until the following day
  • Refrain from applying pressure to the treated areas for 4 hours
  • Gently apply a wrapped ice pack to the injection sites to minimise swelling and bruising


Following your teeth grinding injections for bruxism, you’ll start to notice an improvement 3-4 days later. The benefit will continue to improve, with the most significant effect seen 2 weeks after the treatment. The result will then gradually subside over the following 6-9 months on average, and you can repeat the treatment as needed to maintain the relief from your teeth grinding.

Repeating the treatment before the effect has completely worn off can increase the longevity, and we generally advise combining your teeth grinding injections with other treatment options such as dental splints and pain relief so that you achieve the most significant improvement in your bruxism.

Treating the masseter and temporalis muscles can also give the face a slimmer, more contoured appearance. Most people are very pleased with their appearance after the injections, as their large bite muscles give their face an unnatural square-looking shape. Temple filler and jawline filler can be used if you want to reduce your teeth grinding, and preserve the aesthetic of your face.

    The cost of teeth grinding injections will depend on the extent of treatment which is determined by the severity of your bruxism, and how many muscles are contributing. For a guide on the cost of teeth grinding treatment with injections, please check out our pricing page.

    Certain anti-depressants can cause teeth grinding and jaw clenching. This generally occurs 3-4 weeks after commencing the medication. You should speak to your GP if you develop teeth grinding after commencing new medication.

    When performed carefully with high-quality needles and a gentle technique, injections for bruxism have very little discomfort.

    The muscles that are the treatment targets for bruxism injections are the temporalis and masseter muscles.

    The temporalis muscles are located on each side of the face in the temples, and the masseters are located at the back of the jawline, one on each side.

    The effect from your teeth grinding injections will start to take place 3-5 days after the treatment with the final result being seen at day 14.

    Most people find that the improvement in teeth grinding following anti-wrinkle injections requires maintenance every 6-9 months on average. If you have very strong muscles you may need more frequent treatments initially. Once the muscle has been weakened maintenance treatments can generally be spaced out longer.

    In preparation for teeth grinding injections you should avoid alcohol and intense exercise before your appointment.

    After having teeth grinding injections, you should take it easy for a few days, avoiding alcohol and intense exercise. You should also be careful to not put firm pressure on the injected areas for the first 4 hours after treatment.

    When performed by an appropriately qualified and trained cosmetic practitioner, treating bruxism with teeth grinding injections is categorised as low risk.

    In people with sagging skin and mild to moderate jowls, treating bruxism by relaxing the masseter muscles with injections can make the jowls and sagging more prominent.

    This occurs because reducing the masseter muscle size leads to a lack of structure along the jawline.

    If you are interested in bruxism treatment but concerned about sagging skin and jowls, you can combine teeth grinding treatment with jawline filler and jowl reduction to ensure you preserve the youthful contours of your jawline.

    There is a very low risk of bruising after having injections for bruxism.
