You've got the blackout curtains, the magnesium, the cooling mattress. Nobody told you about your jaw — it's working through every hour you're not awake for. Reviv is a flat, low-profile guard you wear for exactly those hours.
The curtains, the tea, the wind-down — all of it works in the twenty minutes before you go under. The eight hours after that are unattended. Reviv sits between your teeth for those hours, a smooth layer your jaw can settle against instead of pressing tooth-on-tooth.
Most nighttime products want something back — a gummy on schedule, a ring to charge, a score to read at breakfast. Reviv asks for the hours you're already spending asleep and nothing else.
Plenty of guards come out halfway through the night — you don't decide to do it, you wake up and it's on the pillow. Reviv is a flat, even plane with nothing to bite through, and air moves through it instead of stopping at solid plastic. Hold it up to a window: daylight passes clean through the air holes.
The reviews say the same thing over and over: it feels strange, you give it a few nights, then it stops feeling like anything at all. For some people that's a few nights. For others it's a few weeks. Night one is not the night to judge it.
Reviv comes in three sizes and lets you choose. It arrives ready to use — on your nightstand tonight, not after impressions and a two-week wait. Three sizes. No mold, no dentist, no boiling.
The fact that it is flat means it allows teeth to move and space better over time. Which is part of what makes it more comfortable to sleep in over the longer term.
Reviv is the simple alternative to the custom guard. 30,000+ people across 30+ countries sleep with one — backed by a 3,000+ member community and a 1-year replacement warranty. Yours arrives. You use it tonight.

Every option puts something between your teeth for the night. The difference is what you pay, how long you wait, and how long it lasts.
