Do the white strips only whitenen the front teeth?
Do the Crest white strips only whitenen the front teeth, or do they cover the back as well? Do the back teeth even need to be done? Thanks...

They only whiten the front teeth. I move them around though so I can get all of them.
Do they really work? I'm thinking of doing the Zoom whitening at the dentist..but white strips are a heck of a lot cheaper!
The strips work! Your teeth may be a little sensitive. I would try them before you do the Zoom stuff.
I'm actually on day 3 of them and they DEFINITELY work. Plus they have those bonus packs out now that include dental floss, toothbrush, and extra whitening toothpaste. I tell you, it really does looks like a professional.
They work very well. I use the crest premium strips. I only do it once a day because my gums are sensitive.
