Really felt the difference over the past months, I sleep better and my facial structure started to align pretty quickly. Some funny effects as well is that I'm not anxious anymore, more social and not a people pleaser anymore! I switch between the R1 and R1.. the R1 is more comfortable to wear in the daytime, for sleep I prefer the R2

I think at this point, it is the best on the market.

Great mouth guard.

My teeth are straightening out and separating. I've got more energy too

My teeth are already straightening! 5 days of wearing the R2 and I am sleeping through the night, up from 2-4 hours. I wore braces 25 years ago and it took them 18 months to do what the R2 is going to do in a few weeks wearing the appliance overnight and 2 hours during the day. Thank you so much.

I wanted a product like this for adults as soon as I saw them being sold for kids! My teeth and gums were destroyed by orthodontics, I still have crowding even after years of braces and spending thousands on retainers. I’ve only been wearing this 6-8 hrs a night, but my teeth are straightening and I’m sleeping so deeply especially when I use it with mouth tape, since my mouth still doesn’t fully close with the Reviv in.
