Crest White Strips
Hey guys, I've been using these Crest White Strips for about a week, and my teeth are starting to get really sensitive- I had read that that is common, so I expected it. My question is, do you know if it gets worse than this or if it stays pretty constant? Also, have Crest White Strips (or any other form of at-home whitening) worked for any of you?
