Review (5/5): Fantastic!
The Crest White Strips have worked really well for me and I have nothing but good to say about them. I understand that other people have complained that they are tricky to put on and that they were painful, but I experienced neither. I found them easy to apply, I am totally able to speak while they are on (with a slight lisp!), and for me they were not painful at all. My teeth are noticeably whiter and I am very happy with the whole experience. My concern was if they were good for my teeth (I didnt want to accidentally do irreperable damage to my enamel) but a conversation with my dentist solved that completely.
I will definitely use them again if required and wouldn't hesitate to recommend them to others.
