Question:
Has anyone used Crest Whitstrips Supreme?
I'm talking about the ones that you can only buy at the dentist o online. They do not sell these ones in stores, in the US anyway. How did they work out for you?
Thanks!
Answers:
Yes I have. I bought some from my dentist about a year ago. They work VERY good! My teeth are whiter within a few days. I sometimes use them for about a week before going to a major function, for example my best friends wedding. I love them!!
