Reviv is a nighttime jawline mouthguard designed to align the jaw with the natural Curve of Spee. It helps prevent clenching and mouth breathing while sleeping. By protecting posture gains made through mewing, Reviv supports consistent facial structure improvement without nightly regression or reset. Users report better comfort, alignment stability, reduced tension, improved symmetry, and visible jawline definition over time.
