What about Crest Whitestrips?!
Question:
What about Crest Whitestrips?
I've used the premium whitestrips. This time I bought the regular ones, which were almost $10 less (on sale). All made by Crest, all use the same ingredient--but the packages don't indicate a difference in strength or in other ingredients, only a difference in the number of days you use them. Does anyone know the difference between strips?

Hope this helps!
From the Crest website-
With Crest Whitestrips Premium Plus, you will see full results in 10 days - and have a whiter smile for 18 months and it has more whitening agent than Classic, same as Premium.
With Crest Whitestrips Premium you will start to see results after 3 days and full results in 7 days - and have a whiter smile for 12 months and it has more whitening agent than Classic, same as Premium Plus
With Crest Whitestrips Classic, you will see full results in 14 days - and have a whiter smile for 12 months and it has less whitening agent than other Crest Whitestrips.
I didn't see the specific strength or ingredients. What we use in our office are considerably stronger than anything you can buy in the store. Good luck!
