No Pain No Gain
I have found Crest Whitestrips of any version to work really well for me! When I got my braces off my teeth were discolored and i used Crest Whitestrips Classic to make them really white!! There was a little gum sensitivity but it wasn't TOO bad. However, now I am using Crest Whitestrips Premium and WOW by the second day it hurt my gums SO BADLY! I toughed it out and tried it the third day again, but this time i took a Q-tip and i put Vasaline carefully on JUST my gums. It made due for a protective coating and significantly reduced the pain while the Creststrips were on! However my gums are still so sore that i can't even brush my teeth...basically...my Vasaline trick works wonders BUT the Crest Whitestrips Premium are 2X stronger than the Crest Whitestrips Classic, so if your gums/teeth are sensitive I recommend getting the Classic because they really do work for me!
