In this tutorial, we learn how to bleach your teeth for really cheap. First, buy the Plus White teeth whitener kit from a store or online. Once you have the whitening kit, grab plastic teeth molds and see how they fit in your teeth. Once you do this, add some of the whitening gel to the molds, then push them into your mouth on both the top and the bottom. Make sure to rub the gel all the way around your teeth as well so you have a layer of gel all over. Leave this in for the recommended amount of time, then take it out to enjoy your beautiful new white teeth!
