Masseter Botox Edmonton
Jaw slimming and TMJ relief — one treatment, two benefits.
Masseter Botox reduces the activity of the jaw-closing muscle — relaxing chronic clenching and grinding while progressively slimming the jawline over 4–8 weeks. Administered by award-winning CRNA-regulated RN Shayse at 8813 63 Ave NW, Edmonton. Results vary by individual.

All figures are typical ranges. Individual results vary — your plan is determined at consultation.
Two Goals, One Treatment
The masseter is the primary jaw-closing muscle. When it's chronically overactive — from stress, night grinding, or habit — it generates jaw pain AND enlarges the lower face. One injection addresses both. Your dosing emphasis (functional, aesthetic, or balanced) is discussed at consultation.
Functional: TMJ & Bruxism Relief
- Reduces masseter hyperactivity driving jaw clenching and grinding
- Diminishes jaw discomfort, stiffness, and morning soreness
- Fewer tension headaches that radiate from the jaw region
- Lower bite force — less wear on teeth and dental work
- Results typically develop within 2 weeks
Aesthetic: Jawline Contouring
- Progressive jaw slimming as masseter volume decreases (4–8 weeks)
- Softens a square, prominent jawline without surgery
- Creates a more tapered lower facial profile
- Subtle — natural jaw definition preserved, not eliminated
- Can be dosed for slimming emphasis, functional emphasis, or both
How Masseter Botox Works
The masseter muscle enables powerful jaw closure during chewing and clenching. When chronically overactive — a condition called masseter hypertrophy — it generates teeth grinding (bruxism), jaw stiffness, and tension headaches. It also widens the lower face, creating a pronounced square jawline.
Injecting a neuromodulator directly into the masseter reduces its contractile activity. Over 2–4 weeks, the jaw relaxes and clenching force decreases. Over 4–8 weeks, the reduced demand on the muscle causes gradual atrophy — and the jawline visibly slims. The process is reversible: as the neuromodulator metabolizes (4–6 months), the muscle activity returns. Many clients continue maintenance treatments as the effects fade.
Unlike surgical jaw reduction, there is no downtime, no incision, and no structural change to bone. The slimming effect is purely muscular — and can be dialed up or down through dosing. Shayse uses palpation and facial assessment at consultation to map injection points precisely.

Masseter Botox FAQ — Edmonton
What is masseter Botox?
Masseter Botox involves injecting a neuromodulator into the masseter — the powerful muscle responsible for jaw closure and chewing. By reducing muscular hyperactivity, the treatment addresses both functional concerns (TMJ, bruxism) and the aesthetic appearance of a prominent jawline. Administered by a CRNA-regulated Registered Nurse.
How many units are needed for masseter Botox in Edmonton?
Dosing typically ranges from 20–50 units per side (40–100 units total). Factors include individual muscle mass, treatment goals (functional vs. aesthetic emphasis), and biological response. Individuals with particularly robust jaw musculature often require higher quantities. Shayse assesses at consultation and provides a per-unit quote before treatment.
How long does masseter Botox last?
Most clients experience effects between 4 and 6 months. This extended duration (vs. forehead Botox) occurs because the masseter undergoes gradual atrophy from reduced contractile demand. Over successive treatments, some individuals find they require less frequent sessions as muscle volume decreases. Results vary by individual.
Does masseter Botox slim the jawline?
Jawline contouring is a natural benefit as the masseter muscle volume decreases over several weeks. Most clients notice visible slimming at the 4–8 week mark as muscular atrophy progresses. If you wish to preserve your current jaw definition and only address functional TMJ concerns, dosing can be adjusted accordingly. Results vary by individual.
How does Botox help with TMJ and jaw clenching?
Overactive masseters contribute significantly to bruxism and jaw tension. When relaxed through injection, these muscles exert less force during clenching and grinding. The result is diminished jaw discomfort, reduced muscle fatigue, and fewer tension-related headaches that radiate from the jaw region. This is not a permanent cure — effects last the duration of the treatment window.
When will I notice results?
Initial muscle relaxation is often noticeable within 3–5 days. Complete functional improvement — including pain reduction and diminished clenching — typically develops by the 2-week mark. Visible jawline slimming progresses gradually over 4–8 weeks as muscular atrophy develops. Results vary by individual.
Is masseter Botox painful?
Discomfort remains minimal for most clients. Though the masseter is a substantial and dense muscle, the injection process is brief — generally a handful of needle placements per side. Most clients describe it as a brief pinch, comparable to other Botox injection sites.
Are there side effects specific to masseter Botox?
Side effects are generally limited. Some clients experience temporary difficulty with very hard or crunchy foods in the first week after treatment. Rarely, slight asymmetry between sides may occur — skilled practitioners use multiple assessment points to minimize this. Shayse discusses all risks at consultation before proceeding.
Can Botox cure TMJ permanently?
Masseter Botox manages and alleviates TMJ-related dysfunction but is not a permanent cure. Relief is temporary, lasting only during the active treatment window. Many clients incorporate it into a broader TMJ management strategy alongside physical therapy, oral appliances, or postural modifications. Individual results vary.
Who is a good candidate for masseter Botox in Edmonton?
Ideal candidates include anyone experiencing jaw pain, bruxism, clenching behaviors, or associated headaches. Those seeking jawline refinement without surgical intervention also benefit. A consultation with Shayse, RN clarifies whether this approach aligns with your specific concerns and anatomy.
What is the difference between this page and the TMJ Botox page?
Our TMJ Botox Edmonton page focuses on the functional, pain-relief application of masseter Botox — jaw tension, grinding, and headache management. This page covers the full picture: both functional TMJ relief and the jawline slimming aesthetic that comes with masseter reduction. Both are the same treatment; the framing differs by client goal.
Do you see clients from across Edmonton for masseter Botox?
Yes. Clients visit from across Edmonton — Windermere, Glenora, Oliver, Strathcona, Terwillegar, Millwoods, Riverbend, West Edmonton, and Sherwood Park. The clinic is at 8813 63 Ave NW, south Edmonton, with convenient parking and 24/7 online booking.
