CNN.com: If you use salt or baking soda to whiten your teeth, here’s why you should stop
If you regularly enjoy coffee, tea, red wine and pastas with marinara sauce, you might be aware that these foods and beverages leave behind stains on your teeth well after they are consumed.
But if you think you’ve found a whitening solution in the form of table salt (sodium chloride) or baking soda (another type of salt, sodium bicarbonate), think again.
“I see no clinical reason why someone would brush their teeth with salt,” said Dr. Matt Messina, an Ohio-based dentist and assistant professor at the Ohio State University College of Dentistry. “There is no scientific evidence that brushing with salt has any sort of whitening effect on teeth.”
