Using Your Custom Whitening Trays:
Place the whitening gel in the center of each tooth position on the tray so that the gel will rest against the front surfaces of the teeth once it is placed in your mouth.
Wear trays for the time your dentist recommends.
Remove trays and thoroughly rinse your mouth. Gently remove any gel remaining on your teeth with a soft-bristled toothbrush.
Clean the trays after each use with a toothbrush and clear liquid soap.
After whitening treatments, teeth are more susceptible to staining for the first 48 hours. During this time period, you should avoid dark-colored foods or beverages that can stain your teeth. Any item that can stain your clothes can also stain your teeth. Be wary of foods like berries, cola or other dark sodas, red wine, coffee and tea, tobacco, ketchup, soy sauce or other dark sauces.
