Jaw botox (Masseter Botox) is a nonsurgical treatment where botulinum toxin (BTX / Type-A) is injected into the masseter muscle. Through injections, overactive jaw muscles that are involved in chewing relax. Therefore, relaxed masseter muscle leads to an oval-shaped jawline.
Masseter botox prices start from $450 at Vantage Clinic in Turkey. People with hyperactive masseter muscles may experience teeth grinding – bruxism – and jaw clenching. After treatment, the weakened muscles can prevent these conditions for 4 to 6 months.
The masseter muscles are the chewing muscles around the jaw which are thick and slightly rectangular. Doctors use masseter botox treatment to relax overactive jaw muscles. As a result, people can have a slim and oval jawline, and also get rid of some conditions like awake and sleep bruxism.
Doctors use Botox in the masseter muscles because
The anterior masseter is the front part of the jaw. Botox syringe can soften the appearance of a square jawline. It's useful for patients seeking solutions to slim the jaw. You can combine the front part of the masseter muscle botox with jaw filler treatments.
The back part of the masseter muscle, located at the back of the jaw near the ear. Doctors usually prefer 1 cm from the frontal border. Thus, the injections help with both the functional aspects of jaw tension and the aesthetic goal of slimming the jawline. [3]
Botox injections in the lower part of the masseter muscle, near the lower jaw and chin, are used for both functional and aesthetic purposes. Doctors inject it into the lower end of the masseter, close to the jawline, to reduce the strength of the muscle. This relieves tension around the chin. [2]
Cheek injections target the masseter muscles as they connect to the surrounding facial tissues. In this way, the cheeks can be made slim. It can also provide muscle relaxation, which can relieve problems such as headaches, joint stiffness and jaw pain. Cheek Botox can add volume to the cheeks, increase cheekbone definition.

You need to be patient after the treatment of masticatory botox. Initial muscle relaxation may occur in 3 to 5 days; however, you can see the full effects after 2 weeks of injection. After 14 days, you can notice the slimming of the jawline and reduction in muscle strength.
The effects of jawline Botox last about 3 to 6 months.
Botulinum toxin has received official approval worldwide primarily for the treatment of chronic migraine, strabismus, and certain neurological conditions. Although injections into the masseter muscle are clinically extremely safe and widely used for aesthetic jaw slimming and the treatment of bruxism, they are classified as off-label use in the medical literature. Specialist surgeons and dermatologists around the world have been safely using this method for years.
Regular masseter Botox injections administered in very high doses reduce the muscle’s chewing function and, consequently, the mechanical pressure it exerts on the jawbone. Prolonged inactivity of the muscle may, in rare cases, lead to a slight decrease in jawbone density. For this reason, the treatment must be planned under the supervision of specialist physicians, with close monitoring of muscle volume and appropriate intervals between sessions.
Masseter Botox should absolutely not be administered to individuals with the following conditions:
During the first 1–2 weeks following the injection, it is normal to experience rapid fatigue or a slight feeling of weakness when eating hard foods due to temporary weakness in the chewing muscles. During this time, you should avoid chewing gum, eating tough meats, nuts with hard shells, or foods that are excessively high in fiber; instead, you should opt for softer foods that won’t strain the muscles.
One of the greatest advantages of masseter Botox is that, with regular repeat treatments, it makes the muscle’s atrophy a permanent change. Thanks to injections administered at specific intervals (for example, 2–3 times a year), the masseter muscle forgets how to contract forcefully and loses volume. This results in Botox’s effects lasting longer over time and helps extend the intervals between your sessions.
Masseter BOTOX aftercare is key to maximizing the effectiveness of the treatment and minimizing the risk of side effects. In the below, there are some aftercare tips to follow after receiving Botox injections in the masseter (chewing) muscles:
Yes, you can eat immediately after treatment. Just be careful not to drink alcohol and avoid blood thinners for 1 day. You can drink decaffeinated coffee.
Although it is rare, they can. If the injected botulinum toxin leaks into the risorius (smiling) muscle, which is responsible for smiling, temporary lopsidedness or drooping at the corner of the mouth may occur. This is entirely due to anatomical variations and improper injection technique. It does not cause permanent damage. Indeed, it resolves completely on its own within 2 to 3 months.
This risk exists, particularly in certain face shapes. In patients who already have a thin, gaunt facial structure or who are experiencing age-related loss of skin elasticity. Excessive reduction of the masseter muscle can cause the overlying tissue to sag, leading to sunken cheeks or sagging along the jowls. This risk is kept to a minimum with proper patient and dose selection.
In general, Botox masseter is not covered by insurance because people prefer it for cosmetic purposes. However, some insurance companies may cover part of the total cost if you use it for bruxism or temporomandibular joint disorder. So, please ask your provider.
The effects last between 3 and 6 months. The frequency can vary depending on what you expect from the injections.
