Would Crest White Strips work if you used one per week over time?
Like for a year? Or only in the 5 days?

There is no solid answer to this question. Everyone is different, for some people Crest white strips will work and for some it does not no matter how much they use them. So the best way to find out if it would work for you, is if you actually tried it.Source(s): Actively working as a dental assistant.
