Teeth whitening can be pretty expensive, which is why home remedies can be invaluable and worthwhile to try.

I mean, what beats white teeth and nearly free? Very little. That's why this particular home remedy is quite interesting, because it has everything we all have in our own homes.

The secret is aluminum foil. You simply start off by mixing baking soda, salt, and water to make a paste. You then apply this paste to your teeth and apply a layer of tin foil. Leave this for one hour, remove the foil, then brush normally. Repeat twice a week and watch as you get whiter teeth!
