Once you understand what’s actually causing it, it makes sense the approach needs to change too. Instead of peroxide-based whitening (which is what causes that sharp sensitivity for a lot of people)…
👉 PAP helps break down dark smoking stains without using peroxide
👉 Nano hydroxyapatite helps remineralise the enamel
So the surface looks smoother and reflects light better
👉 Enzymes help loosen the kind of build-up that forms over years
That’s exactly what EcoBrightSmile® was designed to deal with — this kind of ‘set in’ yellow that builds up over time.
