Ken Leaver
Reviv Founder
"In 2020 I was exhausted by 6pm and got sick a couple times a year. For the last two years at the age of 47 I work from 8am till past 10pm everyday without burning out. I haven't been sick in over four years and I feel like a beast everyday."

HOW REVIV WORKS
There are some basic biomechanics to how the skeleton and skull work, which result in it collapsing over time.
Particularly if you did orthodontics, extractions, or grind your teeth because those things flatten your 'curve of spee', which is the natural curve of how your upper & lower teeth make contact.
And Reviv essentially reverses that collapse, thereby reinflating the skull and skeleton back to their healthy state.
Addresses TMJ
"I've been wearing my appliance for 3 weeks now. No more TMJ pain at all! I can do chin tuck exercises without my neck muscles spasming and cramping." - Jay
Gives you back energy
"I wear it when driving the bus. A day of work that normally knocks me out the next day had me full of energy. Even when i got home after a very long day. I love this thing!" - George
Eliminates brain fog
"Although i'm a software developer I spent about a year carrying boxes in a warehouse because of the thick brain fog i had. I've been wearing Reviv since early November and brain fog is gone. I just recently started a job working as a developer again!" - Ivan
Fixes posture
"I noticed the other day the area where my neck meets my upper back is more flat . I always had a bit of kyphosis and rounded soldiers and it seems to be correcting." - Harvwin

Step 1: Boil
Fill a pot with enough water to submerge the RevivDay mouthguard without touching the bottom. Bring the water to a gentle boil.
Step 2: Drop
Turn off the heat and carefully place the mouthguard into the hot water. Let it soak for 60 seconds.
Step 3: Retrieve & Cool
Use a slotted spoon to remove the mouthguard and immediately place it into a bowl of cold water for 3-5 seconds.
Step 4: Mold
Stand in front of a mirror and place RevivDay onto your lower teeth. Ensure your teeth sit in the center of the bite channel (not pressing against the side walls).
- Gently bite down
- Press your fingers against the side walls to shape the fit around your teeth
- Keep it in your mouth for at least 5 minutes for best molding results
Step 5: Set
After molding, place the mouthguard back in cold water for 5 minutes to solidify the fit.
Step 6: Ready for Use
Allow the appliance to rest for 24 hours before first use. During this time, the material continues to adapt, ensuring a snug and secure fit.
