R3 (RevivThree)

Amazing. I was at a loss - the first night guard that I can sleep in (and not rip off half way through the night) and weirdly keeps my teeth straighter than ones formed to my teeth

So painful

I wore it for two months straight, hoping I would get used to it. I never stopped salivating excessively, but more importantly it led to so much pain in my gums and my jaw that I had to just give up. I followed the recommendations from Reviv to submerge in hot water and try to refit it so that it was smaller, but that never helped. I don’t think it was too big so much as the design just isn’t what will work for me. I was sad that I spent so much money on it.

Be patient it's worth giving it time

I've used so many different devices, including the expensive ones custom made by the dentist, and this is the first one that has made a noticable difference. To be honest, I hated it that first month. Everything around my jaw and cervical spine felt worse instead of better. My teeth hurt also. I kept using it every night though and now my neck feels stable in a way it hasn't in over 15 years and my teeth/bite alignment has improved with no intervention from the dentist. I was concerned that even though I had purchased the smallest size available, it was still too big for my mouth, but now it seems to fit just fine and I can close my mouth all the way. I'm pretty sure it didn't change, I did.
