Does anyone else have this issue? I constanly grind my jaw becasue of my anxiety and espically at night when I sleep because of the nightmares I have.

Have any of you found any night guards that work well? My jaw is constanly locking up or it hurts to chew. It is quite frustrating and I know it can lead to major dental damage if it gets anyworse, my dentist has told me before that my grinding is an issue and if it doesn't get better he will have to figure something out to do about it, I forgot what he said what it was but he told me to get some night guards or something, and I was wondering if anyone knew of anything that helps with this.
