Reviv is a small direct-to-consumer brand built around one product idea: a mouthguard you wear at night (and, optionally, during the day) that cushions your teeth. It was started by a man named Ken, who says he has worn one every night for four years, and it has grown into a catalog of night guards, a daytime guard, a cleaner, and a set of sleep accessories. This guide covers what each product is, what it costs and how the pricing works. It also covers where the brand's marketing goes far beyond what the evidence supports, because you should know that before you buy.

Bundles and a build-your-own option

Reviv sells pairs such as R3 + RD1 daytime guard ($100, from $120) or R3 + Repod cleaner ($102, from $120), and a build-your-own bundle with up to 25% off.

The R3 night guard

The R3 (RevivThree) is the model the brand points most new customers to. It is a yellow or clear appliance with large airflow channels and a soft-but-durable material, sold in Medium, Large and XL, and the brand rates its gum aggressiveness as "very low" and says it typically lasts 12 months or more. Reviv's own comparison chart sets it against the older R2: both are described as good for grinders, with R3 aimed at more comfort and easier saliva flow.

How the price works. Pricing is unusual. The R3 alone is $80 if it is your first Reviv appliance, $55 if you have bought one before, and $30 if you have bought two. The "with support" version adds one year of access to the brand's community and direct messaging, and costs $150, $125 or $100 on the same scale. The product page also states that all sales are final, so choose your size from the chart carefully.

Daytime guard, cleaner and sleep accessories

The RD2 ($40) is the daytime option, designed to be low-profile enough for work and the gym. The Repod ultrasonic cleaner ($40, or $55 with 30 mint cleaning tablets) is a plug-in cleaner that takes water only, and it is the item most likely to actually improve a nightly-wear routine, because any mouthguard worn every night needs regular cleaning. The rest are simple add-ons: mouth tape and nasal strips ($20 each for 30 days), a soft eye mask ($15), and silicone toe spacers ($20).

What to be skeptical about

This is the part most affiliate pages leave out. Reviv's product pages promote what it calls the "balloon theory": the idea that the skull "collapses" with age and that a mouthguard can "inflate" it, which the brand ties to posture, mood, energy, appearance and even the root cause of disease and aging. These ideas are not established by mainstream dental or medical science, and the site itself states that its claims have not been evaluated by the FDA and that the product is not intended to diagnose, treat or cure any disease. We are reviewing Reviv as a mouthguard and accessory shop, not endorsing those broader claims.

  • See a dentist first. If you have jaw pain, TMJ symptoms, braces or other dental work, get advice before wearing any new appliance every night. The brand itself warns of initial discomfort in the teeth and gums.
  • Mouth tape and nasal strips are not for everyone. If you have sleep apnea, blocked nasal passages or any breathing problem, talk to a doctor before taping your mouth shut.
  • Reviews are mixed. The R3 page shows 72% five-star ratings, but about 1 in 10 are one or two stars. Some reviews shown are from related products.
  • All sales are final on the R3, so check sizing and read the warranty terms.

Bottom line: if what you want is a comfortable, well-reviewed night guard for clenching or grinding, a cleaner to look after it, and a few sleep add-ons, Reviv's catalog is straightforward and priced from $15 to $150. Treat the "skull inflation" claims as marketing, not medicine, and run any nightly routine past your dentist.
