If you have used crest white strips, how long did it take to see results?
Has anyone tried the crest white strips version made for sensitive teeth? And if so, how long did you use them before you saw results?
Also, it says on the directions not to brush your teeth before using them, but doesn’t say anything about after using them. Is it okay to brush my teeth right after using them? I don’t like how the gel tastes.
