crest whitening strips absolutely work, and you shouldn’t use the whole box at once, wait a few months. that drastic of a change is obvious and can make your teeth super sensitive. but they absolutely worked for me. the difference between each one is how many come in the box and how concentrated they are. the 3D white strips I feel are the best balance and price value.
