Oh, the internet’s favorite DIY toothpaste. “Just sprinkle some baking soda on your brush for whiter teeth!” they say. And sure, it can gently polish surface stains away. But here’s the thing: it’s abrasive. Like, sand-in-the-sugar-bowl abrasive. If you use it too often—say, every day for a month—you can wear down your enamel. And enamel doesn’t grow back, friend. Once it’s gone, it’s gone, and you’re left with sensitive teeth that scream when you sip iced tea.
A safer play? Use it once a week max. Mix it with a little water to make a thin paste, and brush gently. Don’t scrunch up your face like you’re trying to sand a floor. Your teeth aren’t a vintage oak table.
