Here are some more tips that may help you when using this product:
1) Make sure to apply the strips to your lower teeth first (it says this in the instructions but I didn’t show this in the video)
2) Align the edge of the strip with your gum line so that it overlaps onto your gums as little as possible…the whitening agent can cause irritation and even white bleach spots on your gums (which fades overnight but still…can’t be good)..this applies for the backside of your teeth as well 🙂
3) I brush my teeth after use and usually clean my lips and apply chapstick, since this product can dry them out a little bit 🙂
I hope you enjoy this product and your newly blinged out teeth!!
