This article aims to explain Masseter Botox treatment along with its side effects and benefits. Keep reading to learn completely.

What is Masseter Botox?

Before starting the topic, it is important to know about Botox and the Masseter.


Botox is commonly known as wrinkle remover in the world of the beauty industry. Nowadays, its other unapproved uses are gaining popularity. Botox is also used as an injectable muscle relaxer that uses a neurotoxin to paralyze the muscle temporarily.

The injections are commonly used to remove wrinkles. Besides, it is often used in masseter muscles to manage facial pain and change face shape.


On the other hand, the masseter is one of your face muscles. It is located on the side of the face which helps in chewing and connects the lower jawbone to the cheeks bone.

When a dermatologist injects Botox into the masseter is called Masseter Botox and sometimes jaw Botox.

This non-surgical method involves the use of botulinum toxin type A in the masseter muscles. The injected toxin temporarily blocks the nerve signals in the masseter and the muscles become relaxed. After the injection, the masseter movement becomes limited, but the person can still chew.

What is masseter Botox treatment used for?

It is typically used for the following reasons:

  • Treating teeth grinding
  • Creating a square and prominent jaw
  • To reduce jaw clenching, stress, and pain
  • Easing or relieving headaches
  • Contouring an appropriate face shape

Botox will not work if a square jaw is a result of the bone structure. This treatment can only fix the jaw if an overactive masseter muscle makes it noticeable.


We have divided the Masseter Botox treatment into three steps. What you need to expect before, during, and after the procedure.

Before the procedure

At the very initial stage, before getting the treatment, make an appointment with a professional. He/she will ask you about your wishing goals and concerns. Make sure to see before and after pictures of the procedure to avoid any disappointment.

After questioning, they will examine your jaw and face to make sure is it suitable for you. Examining helps them to determine the injection site and the number of syringes you need.

After that, they will recall you another day for the treatment purpose.

During the procedure

This is a quick treatment that lasts for only a few minutes. In the procedure, a medical professional will numb the area with topical anesthesia. The treatment provider will clean the skin surface to minimize the risk of infection.

He will prepare a very thin needle syringe of botulinum toxin to inject. After marking the area where the masseter is located, he will insert the syringe. He will then gradually withdraw the syringe while injecting the Botox.

The amount of Botox or the number of syringes depends on your desired results.

After the Procedure

The masseter Botox procedure typically lasts 12 to 15 minutes. After the injections, the treatment provider will massage the injected area. Massage will help to settle the Botox and reduce the risk of bruising and swelling.

The treatment doesn’t require any recovery time, you can resume your usual activities. You need to avoid the following activities for 24 hours after the treatment:

  • Excessive rubbing of the treated area
  • Exercise
  • Hot yoga and Saunas
  • Facial massages

These activities can cause the Botox to transfer to other parts of the face. The full results will come within about 1 week, some people can expect to see results in 1 to 3 days.

The results usually last for 3 to 4 months, so, you can repeat the procedure to maintain it.        


There are many benefits that it offers, but here we break them into the following three.

Minimize symptoms of TMD

The term Temporomandibular joint disorder (TMD) refers to any problem with TMJ. TMJ (temporomandibular joint) is like the masseter muscle that helps to chew.

It acts like a sliding hinge that connects the skull to the lower jaw. Injection of Botox into the masseter muscles can help to reduce TMJ symptoms. These includes:

  • TMJ damage
  • Jaw pain
  • Face, jaw, and ear pain
  • Headaches
  • Jaw locking
  • The low motion of the jaw

Relieve Teeth Grinding

The injection of botulinum toxin weakens the masseter muscle and relaxes the jaw. This in return stops the teeth and jaw from clenching and minimizes symptoms like:

  • Jaw Tightness
  • Neck, face, and jaw pain
  • Tooth pain or sensitivity
  • Headache
  • Ear pain

Sliming the face shape

If you have a square shape of the face and you want to slim it, Masseter Botox may be the best option. Botox creates a V-shaped jawline with its weakening effects.

In this situation, this treatment is also known as masseter reduction or jaw reduction.

Side Effects of Masseter Botox

This is a non-surgical procedure and is usually considered safe. However, as with any treatment, it has some possible side effects that can occur.

  • Swelling and pain at the injection site
  • Drooling

Masseter Botox Cost

The cost of masseter Botox depends on the number of syringes or amount of toxin required for the procedure.

Women’s muscles are smaller and typically they need 20 units of Botox for jaw slimming on one side. Conversely, men’s muscles are bigger, and they need more units than women.

Besides, the cost depends on clinic location, doctor experience, and facilities provided here.

According to some reviews, one unit of Botox costs 10$ to 12$, and 20 units of Botox cost 480$ to 500$.

As it is a cosmetic surgery and not concerned with your health. Therefore, health insurance will not cover the cost of treatment and you have to pay from your pocket.
