QUICK way to get your teeth white. Nite White. You can get it on Ebay or Amazon for around $12. You will need a retainer (I use my retainers I got when I got my braces taken off). If you don't have one, use a sports guard or you can buy one online (ebay). I'll put it this way...Crest white strips have about 2% of the stuff that actually whitens your teeth...this stuff has up to 22%. there's different ones you can buy. They come in syringes, usually a pack of 4. you're welcome :) ps. don't leave it in for longer than 30 minutes...it will causes blisters on roof of mouth or sensitivity. That's how strong this stuff is!
...get a bowl of water, pour little bits of all the different shades you want, it should float on the top, swirl with a toothpick or something like it and when it looks like you want on top of the water, then dip your nails through the water...probably the coolest thing ever!!
