Yes, they do. Anecdotal evidence: I've noticed a definite improvement, but it only lasts a few months. I asked my dentist recently about all these new strip whiteners and he said they were extremely hard on the gums! So beware! Ask your dentist before using them and you dentist can brighten you smile more safely.

It is actually recommended that you brush your teeth after using Crest white strips. This will remove any film left on your teeth from the strips.

White strips are bleach, the use is not needed in children.
The 5 Minute Whitening Gel works great, but so do the Crest White Strips. It's solely a matter of preference.
