Icing™ Advanced Teeth Whitening was developed by celebrity dentist Dr. Raymond Frye, DMD, for his patients. Icing is a special formulation of carbamide peroxide and potassium nitrate that gives patients clinical results at-home. Overnight sessions aren't needed. One 60-90 minute session can yield up to five shades! The Advanced formula kit includes custom tray moulds, carrying case and 2, 3ml syringes - up to 8 sessions. The Advanced formula also features an accelerator light to significantly enhance your whitening experience! Icing gained national recognition when Dr. Raymond began using Icing to do same-day whitening for celebrity red carpet appearances and award show performances. Icing quickly became a celebrity gift bag favorite at the Grammys and Academy Award gifting suites and today Icing is one of the best selling teeth whitening systems today!
