what are some ways to whiten my teeth without a dentist?

my teeth are as yellow as a highlighter.

wow, thats nasty. lol. Why don't you brush two times a day. Also i hear baking soda helps whiten your teeth. Why don't you apply it on your teeth. And also buy the whitening strips, and buy the whitening toothpaste. Also if you do smoke, stop. That will also help.
