Why are custom-fitted trays better than other teeth whitening procedures?

All teeth whitening products on the market work by absorbing into the teeth and lifting stains through the open pores. The key to truly professional results is the custom-fitted whitening trays. These trays ensure that every angle of every tooth receives even and consistent coverage of whitening gel on every tooth (regardless of how straight your teeth are). Custom-fitted whitening trays is the most effective whitening procedure offered by cosmetic dentists nationwide. Note: Ultra-violet light is used in professional dental offices to expedite the whitening process. This procedure is different from blue LED lights used in over-the-counter gimmick product. Blue LED lights have no impact on the whitening results you will receive. Be very weary of products offering LED teeth whitening (and not UV light teeth whitening).
