@2xelitejon: We are officially on Day 4 of the Crest Professional strips with the LED light. Not gonna lie, the process is a commitment, but the progress is starting to show.

Let me know before I finish the rest of this box. 👇 Hashtags #crestwhitestrips #teethwhitening #crest3dwhite #productreview #hygieneroutine
