Winner of a gold medal in the prestigious Edison Awards for innovation, this is the dentist-designed pen that can be used on the go to instantly whiten teeth and prevent staining between whitening treatments. Small enough to tuck into a makeup bag or purse, the slender pen contains a freshening gel and a gentle scrubbing tip that is easily wiped over teeth after consuming coffee, wine, or other discoloring foods, blocking stains from penetrating tooth enamel. The process requires no rinsing or brushing, is safe for daily use, and contains no harsh carbamide peroxide, which can cause sensitivity. Because it helps prevent stains from setting in, the pen can eliminate the need for more extensive and time-consuming bleaching procedures in the future. Gel lasts one month when used daily. 5 1/2" L x 1" W x 3/4" D. (12 oz.)
