What is the best teeth-whitening system that doesn’t involve a dentist trip?

Question by Sam: What is the best teeth-whitening system that doesn’t involve a dentist trip?
I’m trying to find out what is the best teeth-whitening system without going to the dentist for a professional whitening. I’m researching for my fiance, who is in the Marines. Because he doesn’t have the time, as well as all the amount of paperwork he would need to file to get a whitening done, we want to find something over-the-counter. He has really sensitive gums, so I’m nervous for him to use the white-strips. Do the trays seem to work better? Or is there another product someone could recommend? Any suggestions would be great…thanks!

Crest Whitening Strips.
I ususally use them for a week then take a break because, it makes your teeth sensetive.
