The reason whitening hurts is dentinal fluid movement, not damage. Buffering the gel with potassium nitrate calms the nerve response, which is why these sit comfortably for a full thirty minutes when most strips have you pulling them off at fifteen.
Each strip is cut to a real arch shape and grips without sliding, so the gel stays on enamel and off your gums.
Fourteen treatments is a full course. Most people see the change around day five.
