For years I spent all kinds of money on all kinds of "whitening" tooth pastes, mouthwashes and those whitening kits and taste toxic (god only know what they are doing to you). All in the search of white teeth. Nothing ever really did the job. And have you ever noticed how much those whitening gels thingies with the mouth trays sting your mouth. It's like they are trying to burn the stains off or something. In the end I had resigned myself to the fact that I would have to go to the dentist and pay over $1000 to have my teeth professionally whitened.
Then I found OP.
Thank the Lord I found OP & baking soda.
It's cheap.....It's easy.....It's fun..... IT WORKS!!!!!!!!
