I don't really understand the whole teeth whitening thing.
Just brush twice daily, or once for about 5 minutes or so.
I don't know how good bleaching or other artifical colouring can be good for your teeth?
I don't know any products, but be sure to check possible side-effects etc.
Also i would never want me teeth to be THAT white. They look so fake, like a lot of TV presenters etc have them, but excessivley white teeth can also be unattractive. But i guess thats just me
hopefully someone else can be more helpful. Sorry
