The Opalescence Boost Teeth Whitening System is an "alternative, conservative method for treating dark, discolored teeth," which may be used to treat some tooth stains caused by intrinsic factors, including dental fluorosis, tetracycline and trauma. The difference between Opalescence's in-office system and other chairside whitening systems is its chemically-activated gel, which eliminates the need for dental lasers or lights normally used to activate the process. That means no heat or ultraviolet rays, which could be beneficial to patients with sensitive teeth or dry mouth.
