The Technology Difference: Peroxide vs PAP+

The fundamental difference between Zimba and HiSmile comes down to their whitening technology. Understanding this difference is key to making the right choice.

🧪 Zimba: Hydrogen Peroxide Technology

Hydrogen peroxide is the traditional and most widely-used teeth whitening agent. It penetrates tooth enamel and breaks down stain compounds through an oxidation process. This method is proven effective and has been used in dentistry for over a century. However, it can cause temporary sensitivity in some users.

🔬 HiSmile: PAP+ Technology

PAP (Phthalimidoperoxycaproic acid) is a newer whitening agent that whitens teeth without releasing free radicals that can irritate nerves. HiSmile's proprietary PAP+ formula includes added ingredients like hydroxyapatite to strengthen enamel while whitening. This makes it ideal for those with extreme sensitivity.
