Everything You Need to Know About Masseter Botox

The masseter is a muscle located on the side of your face that assists in the chewing motion. Injecting Botox into this muscle can alleviate symptoms of teeth grinding or clenching (bruxism). It can also help make the jawline appear slimmer and more defined.

Botox is an injectable substance that has muscle relaxant effects. It contains onabotulinumtoxinA, a neurotoxin that temporarily paralyzes the muscle.

Botox injections are most commonly used to reduce forehead lines. However, when applied to the masseter muscles (near the cheekbones), it can change the shape of the face and help control facial pain.

This procedure is referred to as masseter Botox. Below, you can find more information about what the treatment is, its benefits, and possible side effects.

What is Masseter Botox?

The masseter is one of the muscles that assist in chewing. It is located on the side of the face and connects the cheekbone to the lower jawbone.

When Botox is injected into the masseter muscle, it is called masseter Botox. It is sometimes also referred to as jaw Botox.

In this treatment, botulinum toxin is used to temporarily block the nerve signals going to the masseter muscle. As a result, the muscle cannot move and gradually relaxes over time.

What is Masseter Botox Used For? Botox applied to the masseter muscle is generally used for the following purposes: Controlling teeth grinding (bruxism) Reducing jaw tension, pain, and teeth clenching Alleviating headaches Slimming a square jawline Creating a more balanced and proportionate facial shape

Below is a summary of what to expect before, during, and after the Masseter Botox procedure.

Before the Procedure

Before receiving masseter Botox, a consultation with a healthcare professional is conducted. During this consultation, questions are asked about your goals and concerns.

Then, your jaw and facial structure are examined. This assessment is done to determine the injection points and how many injectors will be needed.

The procedure itself is performed in a doctor's office. Hospital admission or surgical environment is not required.

During the Procedure

The steps you can expect during the procedure are as follows:

A healthcare professional cleans your skin to reduce the risk of infection. A topical anesthetic cream may be used to numb the area.

An injector containing botulinum toxin is prepared. The injector has a very fine needle.

Then, the needle is placed into the masseter muscle. The toxin is injected while the needle is slowly withdrawn.

If deemed necessary, the same procedure is applied to the other side of the face. The number of injectors used varies depending on the purpose of the treatment.

The procedure generally takes about 15 minutes.

After the Treatment

You can immediately return to your daily activities after the treatment. No recovery time is required.

However, for the first 24 hours, you should avoid the following:

Rubbing the treated area Applying pressure to the treated area Exercising

Such actions may cause the Botox to spread to other areas of the face.

Results are typically fully visible within about 1 week. In some individuals, effects may start to be noticed within 1–3 days.

It should be noted that the effect of masseter Botox is temporary. It usually lasts for 3–4 months. To maintain the results, the procedure needs to be repeated at certain intervals.

What are the Benefits of Masseter Botox?

Benefits of Masseter Botox

Masseter botox offers the following benefits:

Reduces Teeth Grinding

Teeth grinding (bruxism) is usually treated with night guards and lifestyle changes. However, in severe cases of bruxism, botox injections may be more effective.

Botulinum toxin weakens the masseter muscle, allowing the jaw to relax. This prevents the involuntary clenching of the jaw and teeth, reducing the following symptoms:

Jaw tension

Pain in the jaw, neck, or face

Tooth sensitivity or tooth pain

Dull (tension) headaches

Damage to teeth

Ear pain

Reduces TMD Symptoms

Like the masseter muscle, the temporomandibular joint (TMJ) also plays a role in chewing function. This joint acts as a hinge connecting the lower jawbone to the skull.

When there is a problem with the TMJ, it is referred to as temporomandibular joint disorder (TMD). TMD is often seen alongside bruxism and pain originating from the masseter.

When botox is injected into the masseter muscle, it can help alleviate TMJ symptoms by relaxing the muscle. These symptoms include:

Jaw pain

Headaches

TMJ damage

Reduced range of motion in the jaw

Jaw, face, and ear pain

Jaw locking

Slims the Face Shape

Masseter muscles can cause the face to appear more square. If you want your face to look slimmer, masseter botox may be an option.

The muscle weakening effect of botox reduces the volume of the masseter muscles. This results in a slimmer, V-shaped jawline.

When applied for this purpose, masseter botox is also referred to as chin reduction or masseter reduction.

What Are the Possible Side Effects of Masseter Botox?

Botox for the masseter is generally considered safe. However, the procedure can cause masseter botox complications and some side effects:

Pain or swelling at the injection site

Bruising

Headache

Flu-like symptoms

Asymmetrical (crooked) smile

Drooling

Botox should be avoided in the following situations:

If you are pregnant

If you are breastfeeding

If you have an allergy to cow's milk protein

If you have a neuromuscular disease

If you are prone to keloid (raised) scar formation

If you have body dysmorphic disorder

If you have unrealistic expectations

Where Can You Find a Qualified Aesthetic Surgeon for This Procedure?

As with any medical or aesthetic procedure, it is extremely important to work with a specialized or aesthetic surgeon for this procedure. This reduces the risk of complications and helps you achieve the desired results.

You can ask your or family doctor for recommendations to find a suitable surgeon.

During the initial examination (consultation), you can receive detailed information about the procedure and ask the surgeon any questions you may have.

Examples of questions you might ask include:
