What is an easy way to whiten your teeth without going to the dentist?

Or having to blow a lot of money. I use colgate total(which says whitening on the tube) and listerine both AT LEAST twice a day. I have the whitening listerine but I don't like it as much as the regular. I'm just curious as I am starting to see things in the world much differently. Like money, love, girls, psychology, and human nature in general.

There are many teeth whitening from home systems and it worth to try best products. To not spend money ,some offer risk free trial, like Idol White Teeth Whitening or Alta White Teeth Whitening systems (see the source box site for more details).In this way you can test if this really works for your teeth. Use baking soda one time each week (not more to not destroy your enamel). Hope this helps !
