While I was concerned of potential sensitivity to whitening products, I realized that my response to using Crest 3D Whitening Toothpaste was promising and that I should take a chance. I did experience very mild sensitivity on the first few alternating days. These sensations dissipated after rinsing my mouth following each whitening application. By the end of week one, I did see at least a two shade difference. Do contact Crest 3D’s customer service if you have any questions; they are easy to talk to and very helpful. I was reminded by both the Crest 3D rep and my dental hygienist to not exceed a twice a year whitening (6 months intervals). I apologize for not taking photos of before and after so I will try my best to photo-document next time.
