Does anyone have any home remedies/recipes that I can put together to whiten my teeth?

Please keep in mind that although I would like my teeth a bit whiter, I don't want to do anything that may cause damage...thanks!

Actually, this is a funky idea, but it will not damage your teeth, gums or mouth (won't taste too good, but it will work). Put an Alka Seltzer in your mouth then add a 1/3 - 1/2 cup of vinegar. The Alka seltzer will fizz up like crazy and all those lovely bubbles will take stains off your teeth like there was no tomorrow (this also works on the inside of dirty thermoses and hard to scrub toilet spots too). It will feel funky and you should probably rinse your mouth out afterwards (but neither vinegar or Alka Seltzer can ever damage your mouth or teeth!). Do this ince a day for 3 days, you should see some difference.
