Your teeth have tiny holes in them. That’s why they’re yellow. 😬 Tannins, coffee, acidic sodas seep into those micro-gaps and stain from the inside. Most whitening products just blast the stains out temporarily. The holes are still there, so yellow comes right back. The fix is nano-hydroxyapatite. A form of calcium so small it fills in those cracks with the exact same material your enamel is made of. Stains can’t come back if there’s nowhere to go. I recommend grabbing Nobs. Teeth go white and stay white. 🦷 💬 Comment TEETH and I’ll send you the link.​​​​​​​​​​​​​​​​ #philsmypharmacist #nanohydroxyapatite #pharmacyhacks #nobs #teeth
