Masseter Botox: Benefits and Side Effects

by | May 24, 2024

Masseter Botox, also known as jaw botox, is rapidly becoming a sought-after treatment for both aesthetic improvements and medical benefits.

By injecting Botox into the masseter muscles, it helps relax them, reducing jaw tension and alleviating symptoms of temporomandibular joint (TMJ) disorders.

However, like any medical procedure, it’s crucial to weigh the benefits against potential side effects such as temporary weakness in chewing muscles or asymmetrical smile

In this article, you will discover how Masseter Botox can enhance your facial aesthetics and reduce discomfort, alongside a candid look at possible adverse effects. 

What is Masseter Botox?

Masseter Botox involves injections of botulinum toxin into the masseter muscles, which are essential for chewing and significantly impact facial structure.

Beyond its aesthetic value, masseter Botox is also used to treat various issues such as bruxism, TMJ, and persistent headaches.

Studies have shown that Botox reduces muscular activity in the masseter muscle, which decreases muscle spasms and pain associated with nocturnal bruxism. The relief lasts about three months before symptoms gradually return, demonstrating the treatment’s temporary but effective nature.

How Masseter Botox Works

Masseter Botox utilizes botulinum toxin type A to target the masseter muscle, significantly reducing muscle activity and size through a meticulous, medically approved protocol. Typically, 15-50 units of Botox is injected into each of the masseter muscle to achieve optimal results.

The procedure involves the precise injection of Botox into the masseter muscle, significantly reducing its size, which can contour the jawline and alleviate symptoms related to teeth grinding.

This treatment follows a clear, three-stage process:

Stage 1: Binding

The treatment begins with botulinum toxin binding to nerve endings within the masseter muscle. This critical step targets the areas responsible for muscle contraction, preparing the toxin to enter the nerve cells.

Stage 2: Internalization

After binding, the toxin is internalized by the nerve cells through receptor-mediated endocytosis. This phase allows the toxin to penetrate deeper into the nerve, reaching essential areas that control muscle movement.

Stage 3: Flaccid Paralysis

The final stage, flaccid paralysis, occurs when the toxin cleaves specific proteins necessary for releasing acetylcholine, the neurotransmitter responsible for muscle contraction. With the interruption in neurotransmitter activity, the muscle relaxes, reducing both its activity and bulk.

Benefits of Masseter Botox

Masseter Botox became a popular cosmetic procedure not only for its effectiveness in enhancing facial aesthetics but also for its therapeutic benefits. Here are the top benefits that you might experience from undergoing this treatment:

Improved Facial Aesthetics

Masseter Botox can slim the jawline, giving the face a more V-shaped or heart-shaped appearance, which is highly valued in cultures that prefer a softer jawline. The alteration helps balance facial proportions and increases overall facial attractiveness.

Reduction in Jaw Pain and Tension

The procedure is effective in alleviating pain and tension in the jaw, often associated with TMJ. By relaxing the masseter muscle, it reduces stress on the jaw joints and associated muscles, leading to decreased pain and fewer headaches.

Decreased Headaches

Those suffering from tension headaches or migraines triggered by jaw clenching can find relief through Masseter Botox. The treatment minimizes the muscle actions that lead to headaches, offering a non-pharmacological option for headache management.

Minimized Teeth Grinding

Masseter Botox reduces the intensity of teeth grinding (bruxism), which can prevent dental wear and tear. It also reduces the risk of tooth damage and sensitivity.

Enhanced Sleep Quality

By diminishing muscle tension and teeth grinding, this treatment can improve sleep quality. Patients often experience fewer disruptions due to jaw pain or headaches, resulting in more restorative sleep.

Potential Masseter Botox Side Effects

While Masseter Botox is generally safe, like any medical treatment, it does come with potential side effects. It is crucial to be aware of these to make an informed decision:

Discoloration and Swelling

Common issues include slight bruising, redness, or swelling at the injection site, typically resolving within a few days. Some patients may experience changes in their bite or temporary tightness in the jaw muscles.

Muscle Weakness

The treatment relaxes the masseter muscle, which might temporarily reduce the ability to chew hard foods. This side effect generally subsides as the muscle adapts to Botox.

Changes in Facial Expressions

In rare cases, if Botox is not administered precisely, it can affect muscles other than the masseter. It can potentially lead to changes or asymmetry in facial expressions.

Allergic Reactions

Although rare, allergic reactions can occur, presenting symptoms such as itching, rash, red welts, asthma symptoms, dizziness, or fainting. Immediate medical attention should be sought if these symptoms develop.

Jaw Atrophy

Prolonged use of Masseter Botox may lead to atrophy of the masseter muscles, affecting the jaw’s shape. This condition is uncommon but can arise with frequent treatments over many years.

Who is a Good Candidate for Masseter Botox?

Masseter Botox is ideal for individuals experiencing both cosmetic and functional issues related to the masseter muscle. Good candidates include:

  • People with a Prominent Jawline: Individuals looking to soften a strong, square jawline for aesthetic purposes.
  • Patients with TMJ Disorders: Those suffering from jaw pain, tension, and discomfort linked to TMJ can benefit greatly.
  • Individuals with Bruxism: Patients who grind their teeth, especially at night, causing dental damage.
  • Those Experiencing Chronic Headaches: Individuals whose headaches are caused by jaw tension or teeth grinding.
  • Patients Seeking Non-Surgical Solutions: Those who prefer non-invasive treatments to manage and alleviate their symptoms.

Masseter Botox FAQs

How long does masseter botox take to work?

Typically, you might start noticing the effects of masseter Botox within a week after treatment. However, the full benefits, especially in terms of facial reshaping, may become more visible after 2 to 8 weeks as the muscle relaxes and reduces in size.

How long does masseter botox last?

The effects of masseter Botox can last anywhere from 4 to 6 months. Many factors, including your metabolic rate, the number of units injected, and your muscle mass, can influence the duration of the Botox. Regular follow-up treatments are recommended to maintain the desired appearance and benefits.

Does masseter botox hurt?

Masseter Botox injections are generally well-tolerated. The pain experienced is often described as a brief, mild discomfort similar to a quick pinch. Topical anesthetics or ice can be used to minimize pain at the injection site.

What can go wrong with masseter Botox?

While generally safe, complications can arise from masseter Botox if not performed correctly. Potential risks include asymmetry of the jaw, unintended muscle weakness, or difficulties chewing. More serious but rare complications might include allergic reactions or effects on other muscles, which can alter facial expressions.

Is Botox in the masseter worth it?

For many, Botox in the masseter muscle is worth it, particularly for reducing jaw tension, alleviating symptoms of TMJ, and reshaping the lower face to become more aesthetically pleasing. It is important to have realistic expectations and discuss your goals with a qualified professional who can provide tailored advice.
