Masseter Botox Before and After | Jaw Slimming
Masseter Botox for Jaw Slimming
By relaxing the overworked jaw muscle, Botox helps reduce lower-face width and soften square or boxy jawlines — without filler or sugary.
Precise Dosing, Minimal Units
This result was achieved using customized dosing based on facial strength and bite alignment. Results last 4–6 months with maintenance.
Relieves TMJ & Clenching
Beyond aesthetics, this treatment helps reduce TMJ-related pain, nighttime grinding, and tension headaches.
Details of the Treatment
She wanted both a slimmer lower face and relief from the nighttime grinding her dentist had been documenting on her molars. Mouth guards had reduced the dental damage but hadn't changed the jaw width.
On assessment with the patient clenching, the jaw muscles were visibly bulky on both sides. The lower face read wider at the jaw than at the cheekbones, giving a bottom-heavy shape. The wear pattern her dentist had documented was consistent with sustained nighttime grinding. The pattern was both a cosmetic and a functional jaw-muscle issue. Masseter Botox suited this presentation because it reduces both the muscle bulk and the grinding force without affecting her ability to chew normally.
Botox was placed in the lower part of the masseter on both sides, kept well clear of the salivary gland and the muscles around the mouth. In the after image, the lower-face contour has narrowed, the jaw angle reads softer, and the patient reports less morning soreness. One placement strategy addresses both the cosmetic complaint and the functional one. The medical and the aesthetic are not always separate plans.
