Review on Whitening Syringes Carbamide Peroxide Bleaching by Amber Davis

Revainrating 1 out of 5

No carbamide peroxide - I have tested it

I have used 22% carbamide peroxide several times and if stored properly it can last over a year. My husband and I have used it and left it overnight for several days in a row. We don't have the slightest bit of tooth sensitivity, which is unheard of. I just did the oxidizer text on 3 different syringes all negative. This is not a carbamide peroxide percentage. I found the syringes unusually large and versatile. I suspect they were filled with glycerin etc. I think this product is a scam or the seller exchanged it. I don't know who and how, but you don't say that.

Pros
  • Several competitors
Cons
  • unreliable
