Without using any whiteners.
I think it depends, on your teeth and if you brush the right way and floss the right way. Also, some teeth, are a darker color because of the hardness of the teeth, and will stay that way forever unless you use like whitening toothpaste mouthwash things like that.
you should notice a brighter smile within a week or two. depends on the condition of your teeth and products. you should use whitening toothpaste with baking soda in it. works like a charm. =]
