Review on Opalescence Go Whitening Trays - Preloaded, 15% Hydrogen Peroxide - Mint Flavor by Tonya Wolfe

There were a lot of good reviews on this product that made me buy it. However, I'm not sure if this is for drastic teeth whitening or for maintaining already white teeth (which isn't my case). Tried the first set of trays with no success. Tried a second set, they burned badly and were uncomfortable and still haven't seen results. My gums just bled. The next day I couldn't use the third set of splints because my gums were still sore and healing. It took 5 days to fully heal. I don't know if I want to keep using it. I understand everyone is different but keep this in mind if you are considering purchasing this product.
