How can I naturally whiten my teeth?

How can I naturally and safely whiten my teeth?

• I've heard that to whiten your teeth you can use strawberries, lemon juice, baking soda, or hydrogen peroxide, and some others I can't remember. Which is safest and most effective? I know that some of them wear down your teeth enamel or give you mouth problems in the long run. So what can I use that will whiten my teeth, give me fresh breath and kill germs in my mouth, and won't damage anything? It also has to be natural and safe! Thanks :) Please include how to make it and how long until I see results. Thanks again :}

  brush brush brush!! :D uhh, they have a crest toothpaste that has baking soda and hydrogen peroxide already in it :) I just started using it. I don't really know if you'd classify that as natural though. Sorry for not really answering your question right. and since lemon juice has all that acid in it, wouldn't it just damage your teeth?
