R3 (RevivThree)

$150.00 USD

R3 is my personal favorite.

It's incredibly comfortable because it doesn't even touch your gums, so you don't have to worry about irritation. That makes it easy to wear consistently every day.

Made from a firmer material, it's suitable for people who tend to clench their teeth or breathe through their mouth during sleep.

R3 is available in multiple sizes, making it easy to find the right fit and gradually size up as your progress continues. In my experience, it's the most comfortable version I've tried, and each appliance lasts for up to one year.

Whether you're just getting started or looking to accelerate your progress, R3 is suitable for both beginners and experienced users.
