How much does tray teeth whitening cost? Topics | Oral Health | Teeth Whitening | How much does tray teeth whitening cost? 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.
Insurance companies generally try to influence you to choose the least expensive treatment, not the best treatment. Expect to pay $150 to $500 for a white filling, depending mostly on how large it is. Costs also vary from dentist to dentist. This cost information is based on an actual survey of expert cosmetic dentists from coast to coast in the United States, taken in December 2005.
