Are Crest Whitestrips safe?
Yes, they are safe. However, it depends on the person as far as whether you will have sensitivity or not. Sensitivity can occur during or after bleaching, both or not at all. Everyone is different. I recommend my patients use a sensitivity toothpaste (like Crest sensitivity, with Potassium Nitrate) to help during the days you are bleaching. Also, if you do experience sensitivity, you can bleach every other day, rather than daily. But for the price, the white strips are a pretty good buy. 🙂 Good Luck!
