A RealAge answered. You can expect to pay anywhere from $10 to $40 for a tray-based teeth whitening kit purchased over the counter (OTC) from a pharmacy or other retail store. You can also purchase tray-based teeth whitening systems from dentists. These systems feature custom-fit tooth trays or mouthpieces, which is why they are significantly more expensive than OTC tray-based teeth whitening kits. Purchasing a tray-based teeth whitening system from your dentist may cost up to $500.
how much is it on average zoom whitening costs about $ 250 $ 450 per visit but that may vary greatly depending on your dentist and whether there is a need for a pre treatment process
