I haven't used Nite Brite, but I got the Crest Whitening from my dentist and I swear my teeth glow in the dark! It's strips that you leave on for 30min. twice a day. The kit came with a toothpaste that is supposed to keep your teeth from getting new stains and also one of those battery operated toothbrushes. I love it! It's a three week regime and I'm a couple of days into the last week. Good Luck to you!
