To bleach your teeth, simply spread a thin amount in the bottom and against the higher wall of the rubber piece, then pop it in, bite down, and wait. The gel teeth bleach doesn't taste too great but it won't make you gag, either. It also only takes about five minutes, so you won't have to savor that distinct whitening taste for very long. I highly recommend keeping your toothbrush handy during this process, as the gel is pretty thick and won't rinse out easily with just swishing water. When I was finally completely finished and took a glance at my newly bleached teeth, I was pretty impressed.
