Review on 🦷 Introducing Carbamide Whitening: an Effective Solution for Sensitivity and Beautiful Teeth by Keith Mertz

I bought this product hoping it would work because I hate using those strips and trays. The instructions say to dry the teeth, apply a thin layer on the teeth and let the teeth air dry for 30 seconds, do not eat or drink for 30 minutes. I did everything That's the problem, DOESN'T DRY. So when you close your mouth, everything comes out instantly. Total waste. However, I'm keeping it to put in the trays I have because it was so cheap. I think the ingredients are ok, it just can't stay on the teeth long enough to do anything.
