Whitening with KöR
Most whitening disappoints because the gel stops working long before you take the tray out. Saliva seeps in and neutralizes the peroxide, so a tray worn all evening did its real work in the first half hour.
KöR trays seal at the gumline so saliva stays out, and the gels are refrigerated so they arrive at full strength. The manufacturer reports six to ten hours of active whitening per application, against roughly twenty-five to thirty-five minutes for a conventional tray. A desensitizer is built in from the start, which is what stops most people quitting halfway.
Whitening cannot change the color of existing crowns, veneers or fillings. If you have restorations in your smile line, matching them is part of the plan.
