Review: Works! I've been buying for years - I first purchased this whitening gel from my dentist. It works amazing but recommend bleaching trays. I use my Invisalign trays. You just open the syringe by twisting the cap/lid off and applying the bleaching gel directly onto the front parts of your trays. I rub it around with the tip of the syringe, a little goes a long way. If you use too much, the gel will gush out when putting in your trays. if the gel gets on your gums wipe it off! it will cause gum sensitivity. I set a timer for 30 minutes and repeat every couple days (unless teeth are sensitive) until reaching the desired brightness of white. It only takes freshening up twice a year for me. And I drink coffee and tea daily. I'm sure everyone is different. But I always get compliments on how white my teeth are...even if I haven't bleached for a year haha Needless to say this stuff works amazing! You can always use a cheap football mouth guard and form it to your teeth for your "trays". Just bulky but way cheaper
Review: Bright white teeth and a nice minty flavor - I've been using this whitening gel for years and highly recommend it. You can see a difference after using them just once. I've tried both the mint and unflavored versions, definitely go with mint. The mint is a nice light flavor and leaves your mouth feeling fresh when you are done. Not a fan of the unflavored one. If you have sensitive gums or teeth make sure you do not leave this on your teeth too long! This is way cheaper than professional whitening and works well. Good product!
