Having a beautiful smile may be even easier than you think. If you are happy with the shape and size of your teeth, but only want them whiter, our simple home tray procedure may be all that is needed. Although much is made of “One Hour Whitening,” I have found that the home tray method gives equivalent results with more control and less cost. 3 hours a day (or while sleeping) for two weeks usually gives great results, and you can do more or less as you desire. Plus, the trays last a long time, and can be used for reapplying the whitening material for one night every month or so to maintain your beautiful smile.
