What stains your teeth more: Red Wine, Coffee, or Coke? And in which order? Doing a science project, does it matter if we use 1 test subject or 3 different sets of teeth. Not sure if teeth stain the same? ASAP if possible. Thanks

Hands down, red wine. One sip and my lips and teeth are purple for the entire evening. Quite embarrassing for a romantic night on the town :)

The better option is to do the tests on the same set of teeth, or if you use 3 sets of teeth, make sure they all go through all of the drinks. so that you get a more accurate result

I don't know, but I drink a lot of coffee and coke and my dental hygentist told me it's the caffeine in the drinks that causes the stain.
