I don't understand why there is glamorous white, vivid white, and reg. prof. whitestrips options when the goal for all is to have simply white teeth?

I do know that the Glamorous White has fewer strips than the Professional effects -- Glamorous has 32 and Professional Effects has 44 (maybe that's the only difference). Then there is the older version from years ago that don't have the stickier stuff so that they slip around more. But as for the formula, I really don't know what the differences are.

If I have decent white teeth and use these strips in the morning and they brighten my teeth will that brightness fade after I eat?

If you mean after one time, no. If you mean over a longer time, likely. When I drink my coffee or if I have a glass of red wine or staining type berries, I rinse my mouth afterwards and that does help, but over time of drinking my coffee every morning my smile will dull some, but I also use Crest whitening toothpaste and that helps it to last longer. I use the strips about 2 x a year and I've been happy with the results.

Are these okay to use on sensitive teeth?

Yes, I have sensitive teeth and they don’t bother me! I also use the toothpaste before and after I use the strips so that may also help!

can this use for two persons?

Yes, but for the best results we recommend one full kit for one person. The Crest Team
