I grind my teeth really badly; how long does a jaw Botox procedure take? lol

Lately, maybe because of stress, I find myself clenching my teeth really hard when I sleep at night ㅠㅠ When I wake up in the morning, my jaw joint feels so stiff, and my lower face seems to be getting wider, so it's really stressing me out lol. I went to the dentist, and they recommended trying to reduce the muscle tension, so I'm looking into dermatologists! For people who grind their teeth severely Botox I'm wondering if getting the injection really reduces muscle pain and makes my jawline slimmer. Since I'm a working professional, I want to make time to stop by a dermatology clinic after work on a weekday to get it done, but I'm curious about everything from the anesthesia to the finishing touches. Botox Approximately how long does it take? To make your lower face slimmer with a short amount of time investment Botox If there are any seniors here who have been getting this consistently, please share your vivid experiences regarding any side effects lol. I want to get it safely without any hollowing out of my cheeks ㅠㅠ
