Three days left with crest whitestrips..hardly any results?

Question

i have three more days and i dont see much results..a little but not very noticeable Will they turn white once im done or was it just a waste of money?

Answer 1

My son had to use two boxes back to back before he got the results he wanted. Some people have more results quicker than others. He got blinding white teeth when he used Crest Night Effect but this doesn't last long and fades. Great if you have a special function to go too.

Answer 2

I'd leave them on for half an hour rather than 5 minutes. And you can do it twice daily for more results.
