Let's talk about 's masseter neurotoxin moment. First, I love that Hannah has been so open about sharing her experience with the internet. This has been a great educational moment for patients to learn about this treatment.
If you saw the video you may have noticed that her smile looked "off" for a few weeks after getting neurotoxin injected into her masseter muscles for TMJ.
The masseter sits right next to a smaller muscle called the risorius, which helps pull the corners of your mouth out and up when you smile. When neurotoxin migrates even slightly into that muscle, you get exactly what she experienced; a shorter, tighter-looking smile. It's not permanent, it's not dangerous, and it fully resolves as the product wears off over 3-4 months.
What causes migration like this? Usually one of three things: imprecise injection depth, too much product too close to the smile muscles, or anatomy that wasn't mapped out properly before treatment. This is exactly why masseter toxin (Botox, Dysport etc) should be injected by a board-certified professional. This treatment requires real anatomical knowledge of where the masseter ends and the muscles that control your smile begin.
The good news: this is one of the safest, most effective treatments we offer for jaw tension, clenching, TMJ pain, and facial slimming when it's done with precision. I inject masseters weekly, and this kind of complication is rare when dosing and placement are dialed in correctly.
Moral of the story? Masseter Botox is fantastic. Provider selection is everything. 💉
