"I use this product before bed (makes not eating or drinking anything easier) and I've noticed a difference over the last few days! It's no magic bleaching pen, but it definitely works! It takes a few days to notice a difference, so don't expect to use it the night before your big day, but give it a week and you'll notice results. Also, minimal sensitivity even after routine use and I have very sensitive chompers."
