So my first attempt at making something off pinterest was a fail. My teeth whitening substance didn’t last long. I’m not sure if this was supposed to happen, but the next day when I went to brush my teeth, it was all bubbly and super liquidy. I used it any way and it kinda left a weird taste in my mouth. I decided to call it quits on that one. Maybe if one of you tries it, you’ll discover it works! Let me know if it does!
