You're not alone.

Whether you’re dealing with TMJ pain, nighttime grinding, daytime clenching, or just want better sleep and jaw alignment—this guide breaks it all down.

Here’s everything you should know before buying Reviv, in one easy-to-skim FAQ.

1. What exactly is Reviv?

Reviv is a biomechanically designed mouthguard created specifically for:

• TMJ relief
  
  
• Bite alignment
  
  
• Jaw decompression
  
  
• Facial symmetry

Reviv helps reduce or eliminate clenching by:

Most users see dramatic relief in 3–10 nights.
