Hi, which reviv should I buy to start? R1,R2 or R3 and what size?? The size between my first molars it’s 30,75 mm aprox

I'm the only one whose thumbs hurt when thumbpulling? it's reached the point that I've even had calluses from making pressure :( Any tips for the pain?? Soy la única a la que le duelen los pulgares a la hora de hacer thumbpulling? ha llegado el punto que hasta me han salido callos por ejercer presión :( Algún consejo para el dolor?

Hello, i'm wondering what kind of bite i have, as you can see i wear a wire retainer on the back of my upper and lower front teeth, which i brgan to wear after i lost my removable retainers and my teeth moved as a result and this is to keep it from moving more. I have another reviv mouthgaurd on the way, the previous did not fit, will it work?
