Do teeth whitening products work and does anyone know of non-animal tested ones?

I've used one in the past but I'm tryin to find some that aren't animal tested that work and can be bought from supermarkets etc...

These are safe home remedies. Lemon juice, baking soda or baking powder can also be used for teeth whitening. Strawberries are natural teeth whiteners, simply rub them directly on your teeth or mash into a paste and apply.More remedies and information regarding your teeth at http://useinfo-dentalcare.blogspot.com/
