Would square jaw Botox be suitable for a habit of clenching teeth and developed jaw muscles?

Lately, I’ve been concerned because the lower part of my face looks wider and more angular than before in photos. I have a habit of clenching my teeth when I’m concentrating or stressed, and sometimes the area around my jaw feels stiff when I wake up in the morning. My weight hasn't changed much, but when I touch both sides of my jaw, it feels like I can feel hard muscles, so I am looking into square jaw Botox.

Would square jaw Botox be recommended for someone like me who is concerned about both a habit of clenching their teeth and developed jaw muscles? I am also curious how to distinguish during a consultation whether the cause of a wide-looking face is muscle, bone, or fat. I would like to know if the dosage is adjusted differently if the muscle sizes on both sides differ, and what kind of change can be expected when seeking a natural facial contour.

I would like to know if I see immediate changes after the procedure or if they occur gradually over a few weeks, as well as the duration of the effects and the recommended treatment interval. For first-time patients, I am curious about the criteria used to determine the necessary dosage and the price per session. I am also concerned about injection pain, the possibility of bruising and swelling, and whether I might experience discomfort or weakness when chewing after the procedure. I would like to receive full guidance on precautions regarding meals, exercise, and massage on the day of the treatment, and I want to confirm that it is suitable for my condition before starting.
