Masseter Botox with Dr. Grace Kwon at SkinRenew Laser & Cosmetic Surgery

Do you frequently clench your jaw, grind your teeth, or wake up with tight, tired jaw muscles? Overactive jaw muscles can contribute to uncomfortable tension and may even cause the lower face to appear wider or more square over time.
At SkinRenew Laser & Cosmetic Surgery in Modesto, California, Dr. Grace Kwon offers personalized masseter Botox treatments for jaw clenching and teeth grinding. By temporarily relaxing overactive masseter muscles, Botox may help reduce the intensity of clenching while also creating a softer, slimmer-looking jawline in appropriate patients.
Can Botox Help With Jaw Clenching?
Botox may help reduce excessive jaw clenching by temporarily relaxing the masseter muscles, the powerful muscles located on each side of the jaw that are responsible for chewing and closing the jaw.
When these muscles are constantly activated through clenching or teeth grinding, they can become tight, overworked and enlarged.
Carefully placed Botox injections can reduce excessive masseter muscle activity, which may help the jaw feel more relaxed and decrease the strength of involuntary clenching or grinding.
Botox treatment for jaw clenching and bruxism is considered an off-label use, meaning Botox is not specifically FDA-approved for treating bruxism.
What Is Bruxism?
Bruxism is the medical term commonly used to describe involuntary teeth grinding or jaw clenching. It can occur while you are awake or during sleep, and some people do not realize they are doing it.
Signs of excessive jaw clenching or teeth grinding may include:
- Tight, tired or sore jaw muscles
- Teeth grinding
- Morning jaw tension
- Facial muscle tension
- Headaches associated with jaw tension
- Enlarged masseter muscles
- A wider or more square-looking lower face
Because jaw discomfort and headaches can have many different causes, an evaluation is important to determine whether masseter Botox may be appropriate for you.
What Is Masseter Botox?
The masseter muscles are strong facial muscles located along each side of the jaw. They play an important role in chewing and closing your jaw.
Masseter Botox involves carefully injecting Botox into targeted areas of these muscles.
Botox temporarily reduces targeted muscle activity. For patients with excessively strong or overactive masseter muscles, treatment may decrease the intensity of jaw clenching and allow the muscles to become more relaxed.
At SkinRenew, Dr. Grace Kwon evaluates your facial anatomy, muscle strength and individual concerns before recommending treatment.
Can Botox Help With Teeth Grinding?
For some patients, reducing excessive masseter muscle activity may decrease the strength of involuntary clenching and teeth grinding.
However, teeth grinding can have different causes, and Botox may not be appropriate for everyone.
If you are experiencing significant tooth damage, dental problems, persistent jaw pain or symptoms of TMJ/TMD, you may also need evaluation by your dentist or another appropriate healthcare provider.
Can Masseter Botox Slim the Jawline?
Yes, masseter Botox may also create a slimmer-looking lower face in patients with enlarged masseter muscles.
Repeated jaw clenching can cause the masseter muscles to become stronger and more prominent. This can contribute to a wider or more square appearance through the lower face.
After Botox reduces excessive activity in these muscles, the masseters may gradually decrease in prominence. This can create a softer, more tapered and refined-looking jawline.
For some patients, masseter Botox offers both a functional and cosmetic benefit—helping reduce excessive jaw muscle activity while improving lower facial contour.
What Happens During Masseter Botox Treatment?
Your treatment at SkinRenew begins with an individualized consultation.
Dr. Grace Kwon will evaluate your jaw, masseter muscle strength, facial anatomy, symmetry and concerns to determine whether Botox is appropriate for you.
Botox is then precisely injected into targeted areas of the masseter muscles.
The treatment itself is relatively quick and generally requires little downtime. Most patients can return to their normal daily activities following treatment while following the post-treatment instructions provided by our office.
How Quickly Does Masseter Botox Work?
Botox does not work immediately.
Patients typically begin noticing the effects gradually as Botox starts reducing activity within the treated muscles. The timing and degree of improvement can vary from person to person.
Changes in facial contour or jawline slimming generally occur more gradually because the masseter muscles need time to decrease in prominence.
How Long Does Masseter Botox Last?
Botox is temporary.
The length of time masseter Botox lasts varies depending on factors such as your individual anatomy, muscle strength, metabolism, treatment history and the amount of product used.
Maintenance treatments may be recommended to help maintain your results.
Dr. Kwon will discuss an appropriate treatment schedule based on your individual response and goals.
How Many Units of Botox Are Needed for Jaw Clenching?
There is no single number of Botox units that is appropriate for every patient.
Masseter muscles can vary considerably in size and strength. The amount needed may also differ between the right and left sides of the face.
Dr. Grace Kwon evaluates your muscle strength, anatomy, symmetry and treatment goals before determining an appropriate treatment plan.
