Bests & Worsts Reviews from Amazon

At first, I had the same experience as other reviewers: firecrackers on the gums. I was disappointed and determined to make this product work. What I decided to do was paint the gel onto my teeth with a paintbrush, and then put my trays in. This prevents the product from spreading and smushing against the gums, and totally works! Yeah it's uncomfortable to sit with trays in your mouth for an hour, but it's tolerable. I have used one syringe using this method and my teeth are actually getting whiter. Also, you use SO MUCH LESS this way, I feel like the four syringes will last me literally forever. I've whitened my teeth 6 times with just one syringe. And that's AFTER wasting almost half of the tube on the time it burnt my gums after 30 seconds. So those of you who can't make this work or are hesitant to buy it because of the reviews, PAINT IT ON WITH A PAINTBRUSH. Highly recommend this method.
