@doctor_staci: Here's what makes this trend tricky: half of it is genuinely good advice. Baking soda gets a bad reputation it doesn't deserve. Its abrasive index is nearly as low as water, gentler than many conventional whitening toothpastes. It polishes off coffee and wine film, buffers your saliva, and makes your mouth less acidic. Your enamel is a fan. Peroxide is the actual whitener here. It absorbs into the tooth and breaks up stains. But that power is exactly the problem when you freestyle it. The concentration, the dilution, and how long it sits on your gums all matter. Get it wrong and you're risking chemical burns and wiping out your oral microbiome along the way. And even done right, it only lifts surface stains. Naturally yellow teeth won't budge with this. My honest take: use them separately. Baking soda on your brush here and there to neutralize and polish. Peroxide very diluted and only on occasion. Mixing them into one paste creates a reaction you just don't need. Whiter teeth are great. A healthy microbiome and intact gums are better. video credits to @sidandlisten 🤍Doctor Staci
