Optic White Colgate Toothpaste

I've got the Optic White Colgate Toothpaste and I'll keep you updated on how it works.  So far I do see a difference and I've only been using it a few days.... pictures to on my yellow to white smile to come.  I've heard that you can rinse with hydrogen peroxide and get very good results... but I think you should consult your dentist first before heading down that route.  Also, in the past I tried baking soda and it works fairly well; however, its not very convenient and it doesn't taste that great.  Off course there are white strips but being a thrifty Mennonite I find them too expensive.
