Do those home kits really make any remarkable improvement? I have pretty white teeth but not really white, so I've thought about bleaching mine, but my dentist said my teeth were too sensitive. I've tried one home kit that contained sodium chlorine and sodium hydroxide as bleachers, but it made no visible different, except it actually removed all remains of plaque on the inside of the front teeth, that I couldn't brush away. But now there is a home bleaching kit available with karbamide peroxide in it, as the dentists use. It's milder than hydrogen peroxide, but booth are said to make the teeth hurt a little. I don't want to risk pulpititus.
