Recently got both the large Reviv 3. Firstly, thank you so much for making this. It clearly is doing something very significant. I've noticed how i can far more easily create an intra-oral vacuum by doing mike mew's mew-push-swallow whilst wearing the R3.
However, i find after wearing it for about 20 mins to half an hour, it hurts my teeth :(. Is this normal? Shall i just slowly build up?
Feel like i already know the andwer (its gonna be yes), im just looking for reassurance. Thank you.
