@dalebout123 I found the full face mask with the soft memory foam to work the best, especially after I added lip tape. But in the end it was just awful. Will keep you posted but won't see dentist for months and hope to have oral appliance by spring 🙁 I wear a bite guard now so I think getting used to it will be okay. will ask about damage concern, but probably depends on the dental situation you have. I have a crown but that's it.
