How important are professional lab made trays?
Very important, custom laboratory fabricated trays are soft, flexible, and comfortable. They allow you to use less gel and optimize the whitening process by maintaining an even dispersion of the gel over the tooth surface and at the same time minimizing contact of the solution on the gums. This is much better for people who may have sensitivities and ensures an even whitening of the smile. These are the exact same trays that dentists use. Claims other companies make that self moulded trays are just as effective are simply not true – you can never achieve the consistent accuracy that is required for first class whitening with the self moulded tray method.
