I tried the Crest whitening strips and honestly, it was a really disappointing experience. After using them, my teeth became extremely sensitive and even after 4 days I still can’t comfortably drink anything hot or cold, and even biting feels uncomfortable. As for whitening results, there was literally no visible change at all. Nothing. No difference in shade whatsoever. Overall, this product caused discomfort without delivering any results for me. Definitely not worth it based on my experience.
