We tried and tested this amazing Teeth Whitening System and it really works.  Save hundreds of $$ at your dentist by using this dual purpose system which can be applied in chair-side waiting rooms in Salons or Clinics but also for personal at home-use. It is very cost effective and each kit can be used for 25-30 applications. We suggest you use it every other day after your brush your teeth at night for maximum effect. Take a before shade with the guide, Snap open with the Vitamin E stick on one side and allow the gel to flow down via gravity to absorb on the bottom of the stick. Apply absorbed end to the visiblle gu tissues. Tear open the Pre-loaded gel tray and insert into mouth. Plug in the LED Light into the pre-loaded Tray. Prongs on the light fit snugly into the tray. Turn on the light button, treatment time lasts 15 minutes. Do not keep on longer. Turn off the light. Remove Tray and Rinse. Place Tray and light into the Retainer case and back into the pillow box. Take note of Post Whitening shade. If at the Salon or Clinic, allow patient to take home the balance of the system.
