The Functional Activator is a night-time mouth guard that holds the tongue against the roof of the mouth and seals the lips so you breathe through your nose while you sleep. It is aimed at people who snore, wake with a dry mouth, or want to train tongue posture without daytime exercises. Unlike mouth tape, it is a reusable guard with no breathing holes, so the whole seal depends on keeping it in all night. It suits committed nose breathers; anyone with nasal congestion or a blocked nose should not use it.
