This is a great, inexpensive way to whiten teeth, but 30 minutes a day is still hard to fit into my busy routine.

Within four days my teeth were much whiter, although they did become more sensitive to cold.

This was so convenient compared to going to a dentist, and it was easy to use. Most importantly, it worked!

I was amazed with the fast results. Everyone has been noticing how white my teeth are!

I have done the two-week Whitestrips a year ago, for much less, and I do not see the difference between this type of whitening strip and the two other kinds that Crest makes with a lower price tag. Same results as I had last year with just the plain old Whitestrips, and now that I’ve quit smoking, I’m hoping I won’t need to use these again for quite some time.

It did whiten my teeth, and that’s saying a lot because I’m a smoker. However, my teeth are now VERY sensitive, especially the teeth that the strip is tight against. I’m going to try a sensitive teeth toothpaste and hopefully the pain will go away. Not worth it though.
