You can make a paste with baking soda, there is a "recipe" for it on pinterest.

  this is the best way but dont do it to often some people it can make their gums real sensitive . i use baking soda and tooth paste. i olny buy the white paste in general because i noticed if my paste had coloring in it my teeth looked worse

I used to brush with baking soda twice a day, and then with toothpaste. I saw John Travolta on Ellen one time and that's what he said he did lol. Worked for me.
