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.

Purchasing a tray-based teeth whitening system from your dentist may cost up to $500.
