NO PAIN!
This. Is. So. Cool!! Number One absolute best part of this thing is the fact that I felt ZERO pain throughout the process. I've had my teeth Pro-whitened and it hurt so bad during and after that I was basically in tears for 3 days. Naturally, I've been afraid to go back...so I wanted to find an alternative and came across this heat based kit. LOVE IT. No pain and great results! I also have crowns and it was no problem whatsoever. Plus, the kit itself is awesome and super convenient.
