Baking Soda Teeth Whitener: Safe or Very Bad for Your Enamel? When you brush your teeth with baking soda, you are dissolving your teeth enamel. So instead of flashing your pearly whites, you will eventually end up with darker teeth.
Professor Andrew Eder, clinical director of the London Tooth Wear Centre, warns of the dangers of using DIY (do it yourself) teeth whitening products. “Household baking soda is an abrasive, so that with repeated use the white enamel may be worn away and leave teeth browner and with increased sensitivity. Salt crystals will scratch the enamel. Any treatment involving acid is particularly harmful,” he tells the Daily Mail.
