Is it true Botox for bruxism ( teeth grinding) causes bone loss in the jaw and would any bone loss reverse itself with time?

I sometimes wonder, where do people get their information. Using Botox should not cause bone loss. If you're grinding your teeth, ha e jaw pain, definitely go ahead and be evaluated by a plastic surgeon or a dentist who is proficient in the administration of Botox and start using a bite plate. 

There is no evidence that Botox causes any kind of bone loss, Botox is only injected in muscles to help them relax, therefore it will help with the bruxism.  Just be sure your provider is experienced in injecting Botox. 
Best of Luck
