Results vary by patient, but most Seattle providers report 6–18 months of sustained benefit from a full Masseter Botox series.
Most patients wait 24 hours before applying makeup to avoid irritation on freshly-treated skin.
The masseter is the thick chewing muscle at the back corner of your jaw — and like any muscle, it grows with use. Chronic clenching and grinding can enlarge it enough to square off the lower face. Botox partially relaxes the masseter, and over 4–8 weeks the under-worked muscle shrinks (atrophies), narrowing the lower face. The effect is gradual and natural-looking.
It's a big muscle — typically 20–30 units per side (40–60 total), which is why masseter treatment costs more than a forehead area. Severe cases can need more. This is also why per-unit pricing matters more here than almost any other Botox treatment.
Yes — this is one of the best-supported functional uses of Botox. By weakening the clench, it reduces grinding force, protects teeth (and expensive dental work), and relieves the muscle tension component of TMJ discomfort, including morning jaw soreness and tension headaches. Many patients come for the grinding relief and consider the slimming a bonus.
For the first 1–2 weeks, some people notice mild fatigue when chewing very tough foods (steak, thick bagels). Everyday chewing is unaffected — other muscles share the workload. It resolves as you adjust, and a skilled injector doses to avoid meaningful weakness.
Grinding relief starts within 1–2 weeks. The visible facial slimming is slower — the muscle shrinks gradually over 4–8 weeks, with full effect around 3 months. Photos at 12 weeks are the fair before/after comparison.
No — like all Botox, effects fade as the product wears off over 4–6 months and the muscle can rebuild with renewed clenching. That said, after several consistent treatment cycles, many people maintain results with less frequent visits because the grinding habit itself weakens.
