what home remedy will actually work to whiten teeth?

I cant afford the process at a dentist to get them professionally whitened so i was wondering if theres a home remedy that i can do myself?

How to Use Peroxide & Baking Soda for Whiter Teeth 1. Use the right hydrogen peroxide - 3%, and only a variety that doesn't have stabilizers or added chemicals. Check the ingredients list and see that the only ingredients in the bottle are hydrogen peroxide in the 3% strength and distilled water. 2. Mix enough hydrogen peroxide and baking soda together to make a thick paste. 3. Use this as a replacement for your regular toothpaste a few times a week. Make sure to spit all of it out of your mouth. 4. For extra whitening action, you can follow up with a Hydrogen Peroxide mouthwash. Just mix half hydrogen peroxide (again, only the kind with no additives and a 3% strength) with half distilled or tap water. Swirl around in your mouth as long as you can, and then spit it all out. [Under your dentist's supervision, you can also rinse with hydrogen peroxide WITHOUT diluting it with water. If you have inflamed gums, this can help reduce the inflammation, too. Just make sure you don't swallow it!] You will definitely notice your teeth getting whiter if you do this on a regular basis! As with any dental routine, make sure to check with your dentist or hygienist to make sure they approve of this new dental technique.
