Frequently Asked Questions

Mild tightness for the first three to seven mornings is normal and passes. Start on the lowest setting and only move up when the previous setting feels like nothing. If soreness lasts beyond two weeks, drop a setting and email us.

Crowns, bridges and implants are generally fine. Fixed braces are not — it can't mould cleanly around brackets. Ask your orthodontist first if you're mid-treatment.

Standard fits most adult jaws and holds advancement more firmly. Choose Slim if you have a narrow arch, sleep on your side, or found previous guards bulky. Either can be exchanged free within the trial.

Then the source probably isn't your jaw. Try Contour if it only happens on your back, or Vent if you're congested. Return it within 120 nights for a full refund either way.

Vent widens the nasal valve, but it can't clear congestion from inside the nose. If you're very blocked, it may feel less effective until the congestion passes.

Rinse under cold water each morning. Soak weekly with a Nightly Rinse tablet to dissolve any overnight film.

Every three months, or sooner if the material feels stiff or the fit loosens.

Vent addresses the nasal valve specifically. If mouth breathing continues, pairing it with Glide addresses the jaw at the same time.
