Our masseter muscle is located on either side of our jaw. If overused from teeth grinding or chewing, our masseter muscles can enlarge and you might experience headaches. Anti-wrinkle injections such as Botox relax the masseter muscle and reduce the size of the muscle making the face slimmer and treating any pain caused by grinding or headaches.


A local anaesthetic is first applied to the injection sites on your face. Once you are ready, small quantities of the Anti-wrinkle treatment are injected into the Masseter Muscle on either side of your jaw.


Anti wrinkle is suitable for most people; however, this treatment should be avoided by anyone with muscle problems, nerve damage, or pregnant or breastfeeding.

Masseter Botox

The masseter is one of the muscles on either side of your face that helps you chew and connects your cheekbone to your lower jawbone. Botox or other anti-wrinkle injections that are injected into the masseter, are a safe and effective aesthetic treatment that relaxes the overactive masseter muscle for facial slimming and to prevent tooth grinding. Anti-wrinkle injections such as Botox or other brands are administered by our highly qualified aesthetic doctors after a complimentary consultation to ensure you are seeking the treatments best suited for you.


The common side effects that occur with thread-lifting and anti-wrinkle injections are generally connected with the injections sites and usually resolve themselves within two days. They include:
  • Swelling
  • Bruising
  • Soreness
  • Temporary skin dimpling
  • Redness
  • Pain
  • Itching
  • Discolouration
These generally resolve within 2 – 7 days.


  • Massage the face for two weeks
  • Avoid direct sunlight and tanning machines
  • Avoid alcohol and aspirin, ibuprofen and Advil for seven days before and after treatment
  • Avoid blood thinning vitamins A,C and E for seven days
  • Avoid physical exercise for seven days
  • Avoid heat treatments on the treated areas for 10 weeks
  • Avoid temperature extremes


Masseter treatment should last around 3-4 months. You can expect to see full results in about 1 to 2 weeks. It’s worth noting that the effects of anti-wrinkle injections are temporary. They usually last 3 to 4 months. If you’d like to maintain the results, you’ll have to repeat the procedure. A plan for regular follow-up treatments will be put together for you.

The Benefits of Masseter Botox

  1. The Benefits of Masseter Botox Facial Harmony: Anti-wrinkle injections such as Botox can help achieve a balanced and proportional facial appearance by slimming down an overly square or prominent jawline. This treatment can enhance the overall harmony of your facial features, creating a more aesthetically pleasing look.
  2. Non-Surgical Approach: Unlike surgical jawline reduction procedures, anti-wrinkle injections are a non-invasive treatment. It involves minimal discomfort, no incisions, and requires no downtime. You can resume your daily activities immediately after the procedure.
  3. Tailored Results: One of the significant advantages of Masseter Botox is that the treatment can be customised to suit your desired outcome. Your healthcare professional can adjust the dosage and injection technique to achieve your desired level of jawline slimming, ensuring natural-looking results.
  4. Long-Lasting Effects: While the results of Masseter Botox are not permanent, they can last anywhere from 4 to 6 months, depending on individual factors. Regular maintenance treatments can help maintain the desired jawline shape over time.

Masseter FAQs

Botox or other anti-wrinkle injections work for teeth grinding by targeting the masseter muscles involved in clenching, and grinding the teeth. When anti-wrinkle treatment is injected into these muscles on either side of the face, it paralyses the area leading to muscle relaxation.

By reducing the activity of the jaw muscles, Botox helps alleviate the clenching and grinding associated with jaw clenching or teeth grinding. The effects of Botox for teeth grinding are not immediate, and it may take a few days to start noticing a reduction in symptoms.

Masseter Botox, also known as jawline Botox or masseter reduction, is a cosmetic procedure that involves injecting Botox into the masseter muscles to achieve a slimming effect on the face. The masseter muscles are the main muscles responsible for chewing, and when they are overdeveloped it can result in a wider or more square-shaped face.

Using a fine needle our doctor will carefully inject small amounts of anti-wrinkle treatment into the masseter muscles causing the muscles to relax and reduce in size over time. This can lead to a slimmer and more contoured appearance of the jawline and lower face.

When Anti-wrinkle injections, such as Botox, are injected into the masseter muscles they can provide relief for some people who suffer from migraines by reducing the frequency and severity of the migrane.

Migraines can be triggered or made worse by muscle tension and tightness. The masseter muscles, which are involved in jaw movement, can contribute to this tension. By injecting Botox into the masseter muscles, the muscle activity is temporarily reduced, leading to muscle relaxation. This can help in preventing migranes or stopping them from getting worse.


Botox for bruxism refers to the use of Botox injections as a treatment for teeth grinding or clenching, which is medically known as bruxism. Bruxism can lead to various symptoms, including jaw pain, headaches, tooth damage, and other dental issues.


The Masseter Botox Treatment Experience

  1. The Treatment Experience Consultation: Your journey with Masseter Botox begins with a consultation with a qualified healthcare professional. They will assess your jawline, discuss your goals, and determine whether you are a suitable candidate for the treatment.
  2. Treatment Procedure: On the day of the procedure, the targeted areas of your masseter muscles will be identified, and a topical numbing cream may be applied for added comfort. The Botox injections are typically administered using a fine needle, with the entire process usually taking 10 to 15 minutes.
  3. Recovery and Results: After the treatment, you can resume your normal activities immediately. However, it is advisable to avoid rubbing or massaging the treated area for the first few hours. Over the next few days and weeks, you will gradually notice the effects on your Masseter muscle as your jawline becomes slimmer and more contoured.

Could not recommend Eden Medical, Dr Emma and Valerie enough and I would highly recommend them to anyone looking to have treatments done. They are so welcoming and friendly, you are put at ease the minute you arrive at the clinic. I am over the moon with the results from my visit, better than I could have even expected!!! Dr Emma is so knowledgeable and gave me great advice on what treatments would suit me but with no pressure to have to have those treatments done if I did not want to myself. The treatment I had done was virtually pain free. I will 100% be back. 5 star clinic 💫💫💫💫💫

I have been to Dr.Emma in the cork clinic for lip fillers a few times now and I honestly wouldn’t go anywhere else. Anytime I go to my appointment she makes me feel at ease straight away she’s so professional and very gentle. In the past I’ve went to different clinics and the difference in results definitely shows in terms of her professionalism and knowledge, to hygiene and technique.

I went to Eden medical for my first ever treatment of anti wrinkle injections and I could not recommend them enough. They are so friendly and helpful. I was really nervous going in for the first time and they made me feel super comfortable. Dr.Cliona took the time to talk me through everything pre injection and post injection. My treatment was amazing. I was given a follow up check a few weeks later to see how I was getting on too. Their premises is also fab. I can’t wait to go back. 🙂
