Has anyone had botix for bruxism and has it worked? I have had a mouth guard at night for a few years but clenching and grinding my teeth continues... with migraines and more damage to my teeth. Saw the dentist today who is referring me for botox. Has anyone had this and did it work? Can I also sneakily ask for my 11s to be done at the same time ;) Honestly though the jaw aches and head aches need to stop...
