The MySmile Teeth Whitening Gel Box includes four pieces of 35% Carbamide Peroxide non-sensitive gel, a shade guide, and an instruction manual (Led light mouth tray not included). With its enhanced formula, the gel delivers visible whitening results in just 10 minutes, effectively removing stains from coffee, smoking, wine, soda, and tea. Unlike other products that may increase the risk of tooth decay due to sweeteners, MySmile s gel is gluten-free, kosher, and sweetened with Xylitol, which reduces decay risk while being gentle on sensitive teeth. Easy to use, it requires only one minute of preparation and 10 minutes of application, promising up to 20 shades whiter teeth in seven days. Clinically proven and trusted by millions of happy customers, the gel is made in the Usa by Oratech Llc, a company with over 40 years of experience and recommended by over 25,000 dental offices.
