As a dental professional it is important to me to use safe and effective whitening products. Out of all the white in products I've used I prefer Nite White Excel! Minimal sensitivity. If I experience sensitivity, I skip a day or two and resume once sensitivity is gone. Takes one to two weeks to get very bright white results. Once you get the white shade you prefer, you can touch up every couple of months. Just be cautious not to drink dark liquids or sauces which can delay whitening and cause a lite tint if consuming during whitening. Great price! Fast shipping!
