Our laboratory will take your impressions and scan them so that they can do a 3D analysis of the number of months of treatment are required. The trays are made of clear plastic and numbered so that you will know which aligner to wear next. Once you place your order for the number of months of required treatment, we will send you a set of bleaching trays and bleach so that you can start whitening your teeth while the Clear Aligners are being made. Once you place your order, the lab requires 10-14 days to manufacture all of your Aligners. You will receive all of your required Aligners at one time and they will be numbered so that there is no confusion. Each aligner is worn for 15 days and must be worn all day except for when you eat or brush your teeth. You clean the Clear Aligners with a toothbrush and toothpaste with cool water daily or more as required.
