Masseter Botox in Toronto – TMJ Relief & Jaw Slimming Near Hwy 7 & 400
If your jaw feels tight, you wake up with headaches, or you’ve noticed your lower face looking wider over the last few years, you’re not imagining it. Overactive masseter muscles (the big chewing muscles along the jawline) can cause TMJ-style pain, teeth grinding and a bulky, square jaw.
The good news? You don’t have to live on painkillers or hide your jaw in photos.
Masseter Botox in Toronto & Vaughan offers a non-surgical way to relax clenching, protect your teeth and subtly slim the jawline—all with a quick, nurse-led treatment.
What Is Masseter Botox?
Masseter Botox is simply neuromodulator injections (Botox® or Dysport®) placed into the masseter muscles on each side of your jaw.
By softening the overactive chewing muscles, Masseter Botox can:
Reduce jaw clenching and grinding (day and night)
Ease TMJ discomfort, facial tightness and tension headaches
Gradually create a softer, more V-shaped jawline
Protect your teeth from constant grinding over time
At Face Injectables, treatments are nurse-led, anatomy-guided and customized to your individual muscle strength and goals—whether that’s mostly medical relief, aesthetic jaw slimming, or both.
Who Is a Good Candidate for Masseter Botox?
You may be a strong candidate for Masseter Botox in Toronto or Vaughan if:
You grind or clench your teeth (with or without a night guard)
You wake up with jaw stiffness, fatigue or headaches
Your dentist has mentioned wear on your enamel or flattened teeth
Your jaw looks wider or more square in photos than it used to
You feel constant tightness when talking, chewing or during stress
Many clients at our Vaughan clinic (near Hwy 7 & 400) drive in from Toronto, North York, Etobicoke, Mississauga, Brampton, Richmond Hill, Markham, Aurora, King City and Caledon specifically for TMJ and jawline-focused Botox. They want medical knowledge plus an eye for facial balance, not a rushed, one-size-fits-all treatment.
How Much Masseter Botox Do I Need?
Dosing is always customized, but a typical starting range is:
Total masseter dose: ~30–60 units (both sides combined)
During your consultation, your nurse will:
Palpate (feel) your masseter muscles while you clench
Assess muscle thickness, asymmetry and bite pattern
Discuss whether you’re focused on pain relief, jaw slimming, or both
Build a plan that fits your goals, anatomy and budget
At Face Injectables, our standard rate is $9 per unit (Botox®/Dysport®).
Most clients combine masseter with at least one upper-face area (like forehead lines, 11s or crow’s feet) for a more balanced, refreshed look.

What Results Can I Expect?
Timeline
7–14 days: clenching usually begins to ease, bite feels less “locked”
4–6 weeks: jawline can start to look softer and less square as the muscle relaxes
6–8 weeks: best contour change and full comfort effects
3–4 months: results typically last this long before gradually wearing off
Most clients schedule their second session at around the 3–4 month mark, then stretch to slightly longer intervals once they reach a stable, comfortable result.
How It Feels
Treatment time: usually 20–30 minutes
Numbing: not always needed, but can be used for comfort
Sensation: quick pinches with a very fine needle
Downtime: you can typically return to work or errands right away
You’ll receive simple after-care instructions (no intense workouts the same day, avoid lying flat for 4 hours, no facials/lasers for about 2 weeks on the treated area).
Masseter Botox for TMJ vs. Jaw Slimming
One of the best parts of Masseter Botox is that medical and aesthetic benefits often overlap.
For TMJ & Teeth Grinding
If your priority is pain relief and protecting your teeth, the goal is to:
Reduce overactivity of the masseter muscles
Ease tightness and tension headaches
Keep chewing comfortable (not overly weak)
Expect your nurse to start with a conservative dose and adjust over time, based on how your jaw feels day–to–day and what your dentist sees at check-ups.
For Jawline Slimming
If you’re focused on jawline contour, the aim is to:
Use dosing patterns that subtly debulk the masseter muscles
Maintain a natural, proportional look with the rest of your face
Avoid the overdone, “hollow” look by respecting your bone structure
We’ll also look at your chin, lower face and neck to see if small tweaks (like chin dimpling, DAO, or a Nefertiti Lift) might enhance your jawline result without adding filler.
Is Masseter Botox Safe?
When performed by an experienced injector using Health Canada–approved products, masseter Botox is considered safe and well tolerated.
Possible short-term effects can include:
Mild tenderness at the injection sites
Small bruises (especially if you bruise easily)
Temporary chewing fatigue while your muscles adjust
Serious side effects are rare, and your nurse will review your medical history, medications and previous injectable experience before creating your plan.
If you also wear a night guard, Masseter Botox can work alongside it to reduce the strength of clenching, offering extra protection for your teeth and jaw joints.
