The Sleepover Guarantee: 60 or 90 nights

Your jaw needs a little time to get used to wearing a mouthguard. That is why you get 60 nights with the Single kit, or 90 nights with The Pair and the Complete Kit, counted from the day your order is delivered, to decide whether it is right for you.

Count your nights.

They start on the day your order is delivered. Choose your kit and enter that date to see your last night.

Why 60 to 90 nights.

A mouthguard is not something you judge in one night. Your jaw may feel slightly forward when you wake up at first, and that fades. Light soreness is possible in the first few days.

Sixty nights is long enough to mold it, start at neutral, try a step or two, and decide with a few weeks of your own nights. The Pair and the Complete Kit get 90, because two people rarely settle in at the same pace. It is also why the guarantee exists: every mouth is different, and it may not fit everyone.

A mouthguard takes a few nights to get used to. That is why our guarantee lasts 60 nights, or 90 with The Pair. If it is not for you, write to us and we refund the full price.
