Masseter Treatment for Jaw Clenching & TMJ Symptoms
Masseter neurotoxin treatment places a small amount of neurotoxin into the masseter (jaw) muscle to help reduce muscle activity associated with clenching, grinding, and tension. For some patients, it may also soften a heavy or square jawline. Care at RANDALI is physician-directed and individualized. Appropriateness is determined during a confidential consultation.

What it is, and what it addresses
How it works
The masseter is one of the muscles that powers the jaw. When it is overactive, from clenching (bruxism), grinding, or habit, it can contribute to muscle tension, soreness, and a more prominent jaw shape. Relaxing the muscle with a targeted neurotoxin may help ease that tension and, for some, gently soften the jawline.
It is important to understand what this treatment does and does not do: it addresses muscle activity, not the temporomandibular joint (TMJ) itself. It is not a treatment or cure for a TMJ joint disorder (TMD). If a joint problem is suspected, your provider may recommend a dental or medical evaluation.
Using neurotoxin in the masseter for clenching, grinding, or TMJ-related muscle symptoms is an off-label use. This page is educational; your provider determines whether it is appropriate for you.

Questions, answered
Frequently asked questions
Does masseter Botox treat TMJ?
It addresses the muscle activity (clenching, grinding, tension) that can contribute to jaw discomfort, not the temporomandibular joint itself. It is not a treatment or cure for a TMJ joint disorder. If a joint problem is suspected, your provider may recommend a dental or medical evaluation.
Is this use FDA-approved?
No. Neurotoxin use in the masseter for clenching, grinding, or TMJ-related muscle symptoms is off-label, used at the clinical judgment of a licensed provider and not FDA-approved for this specific purpose. Your provider will review this with you.
Will it slim my jaw?
For some patients, relaxing an overactive masseter can gently soften a heavy or square jawline over several weeks. Results vary and cannot be guaranteed.
Will I still be able to chew?
Yes. Dosing is individualized to relax, not paralyze, the muscle. Some patients notice mild chewing fatigue at first, which typically settles.
How soon will I notice a difference with masseter treatment?
Muscle relaxation typically builds over one to two weeks. Jawline softening, if it occurs, develops more gradually. Individual results vary.
Does masseter treatment hurt?
The injections are quick and most patients tolerate them well. Mild soreness afterward is common and temporary.
How long does it last?
Effects are temporary, typically lasting about 3–4 months. Maintenance needs vary by individual.
How much does masseter Botox cost?
It's priced the same as our standard neurotoxin treatments, by the unit. This page is educational; it isn't a separate procedure with separate pricing. Your provider reviews the specifics with you.
How do I know if I'm a candidate for masseter treatment?
Candidacy is determined during a confidential consultation, where your provider evaluates the muscles and discusses your goals, expectations, and the benefits and limitations.
