Men usually need a higher dose, while women—especially mature women—often need 25–50% less to relax the jaw without changing natural expression. It’s also normal for one side of the face to need more units than the other, depending on which side you chew on more. During your consultation, your injector will assess your muscle strength and overall facial balance, especially if Masseter Botox is part of your Botox plan for softer, more elegant contouring.

Is Masseter Botox Safe? Risks, Over-Injection & What to Avoid
The masseter is a big, strong muscle, so it needs a proper amount of Botox to work well. If the dose is too low, the muscle won’t soften, and you won’t see a change. At the same time, the goal is not to completely relax or “freeze” the muscle — you still need it for chewing. What we want is a gentle shift from hyper-tone → normal tone, which feels more comfortable and looks more balanced.
The depth of the injection is just as important. If Botox is placed too superficially, only part of the muscle relaxes, and the rest can overwork — this is what sometimes creates an uneven shape when you clench. Proper masseter treatment targets the deeper part of the muscle and keeps a safe distance from the edges to prevent migration into nearby muscles that affect your smile.

Choosing an injector who understands:
- the right dose for your muscle strength
- how to restore normal muscle tone (not over-relax it)
- the correct injection depth
- the safe injection points
…makes all the difference. When these steps are followed, Masseter Botox in Toronto is a very safe, reliable treatment with smooth, natural-looking results. If you are not ready for injections, you can try Endospheres facial to relax your muscles and remove facial swelling.
Who Is Not an Ideal Candidate for Masseter Botox? (Menopausal Considerations)
Masseter Botox can work beautifully for many mature and menopausal women, but the treatment must be customized with extra care.
During menopause, several muscles in the lower face often become hyper-toned, contributing to early jowls and a heavier jawline. These include the chin muscle, the muscles that pull the lip corners downward, and parts of the platysma that reach up toward the mouth. If the masseter is relaxed on its own while these surrounding muscles remain overactive, the extra skin in the lower face can become more visible. This is why mature clients often get better results with a balanced lower-face approach, similar to a gentle full-face Botox plan rather than masseter-only injections.

Instead of placing the full 20–40 units into a single muscle, MedVSPA Toronto injector may spread a portion of the dosage across the entire lower third of the face—the chin, jawline, depressor muscles around the mouth, and masseter. It keeps the jawline supported, reduces the downward pull around the mouth, and softens jowls for a naturally lifted look. When performed this way, Masseter Botox becomes a safe and effective option for mature women, offering comfort and subtle contour without creating imbalance. Is Masseter Botox Right for You?

Masseter Botox FAQ
1. How long does Masseter Botox take to work?
Most clients feel jaw tension easing within a few days, with visible facial slimming appearing around 2–4 weeks. Full results continue to improve as the muscle softens and becomes less overactive.
2. How many units of Masseter Botox do I need?
The dose depends on the strength and size of your masseter muscle. Most clients require 20–40 units per side, while mature women and those receiving full-face Botox often need less for balanced, natural contouring.
3. Will Masseter Botox change my smile?
When performed by an experienced injector, Masseter Botox does not affect your smile or expression. Proper depth, correct injection points, and accurate dosing ensure the surrounding facial muscles remain unaffected.
4. Does Masseter Botox help with TMJ or teeth grinding?
Yes. Relaxing the masseter muscle often reduces clenching, headaches, morning jaw tightness, and overall TMJ discomfort. Many clients report both functional relief and a softer jawline.
5. How long do Masseter Botox results last?
Results typically last 4–5 months, depending on muscle strength and metabolic rate. With regular treatments, many clients find their results last longer as the muscle becomes less overactive over time.
6. Can Masseter Botox slim a square or wide jawline?
Yes. By reducing masseter bulk, the lower face looks slimmer, softer, and more contoured. For enhanced definition, some clients combine Masseter Botox with chin Botox or jawline contouring filler.
7. Is Masseter Botox safe for mature or menopausal women?
Yes, but the treatment should be customized. Mature clients often benefit from a balanced lower-face approach so the skin remains supported while jaw tension is reduced. Your injector will assess whether masseter-only or full-face Botox is best.

Temporary swelling, mild tenderness, or slight chewing fatigue may occur. Rarely, improper placement can affect smile dynamics, which is why choosing an injector with deep anatomical knowledge is essential.

Yes. Chewing habits and natural asymmetry mean many clients require different doses on each side. Customized dosing ensures balanced results and natural facial symmetry.
