[Botox] Clenching the teeth after botox

I got botox in my jaw in early May and started transparent braces in early July, but lately I've been waking up with my jaw clenched all the time... My jaw muscles have also gotten a lot stronger. Is this because I started transparent braces or is it one of the side effects of botox? I live in the countryside and I'm visiting relatives in Gangnam, so I'm going to go get botox again. Will it help with my jaw clenching? Dentists usually do it for patients who brux.
