How does the
Process of teeth whitening?

Tooth discoloration is caused by various dyes and pigments that adhere to the tooth surface over time. There are two ways to whiten teeth: removing the existing plaque and chemically whitening the shade.

Plaque removal is a physical process that targets surface stains using an abrasive method. This means that the plaque is removed through friction, revealing the underlying tooth color.

Chemical whitening, on the other hand, is a bleaching process that works on both superficial and deep-seated stains, as it actively lightens the actual color of the teeth. Chemical whitening is therefore the most common and effective method for achieving whiter teeth.

How does chemical bleaching (peroxide) remove stains from teeth?

Tooth whitening through chemical bleaching oxidizes stains and alters the molecules responsible for color retention. Simply put, when the bleaching agents penetrate the tooth enamel, they break down the molecules into smaller, simpler forms, making the overall tooth color appear whiter.

Common bleaching agents include hydrogen peroxide, carbomide peroxide and phthalimidoperoxicaproic acid (PAP for short).

Why isn't PAP used more often?

Most dentists still use peroxide-based treatments for in-office bleaching in their practices, as the use of PAP has not yet been fully researched due to its complex formulation. The higher the pH value of PAP, the more effective it is. Unfortunately, this reduces the shelf life of the products, which is why the effectiveness can diminish after just a short storage period if the formulation is incorrect.

In addition, the side effects of peroxides during in-office bleaching can be monitored by dental staff, minimizing the risk of long-term damage to the tooth. This is different with home bleaching products containing peroxides, where caution is always advised.

What makes PAP+ so special?

It was clear to us that we wanted to leverage the benefits of PAP in our products without compromising durability and effectiveness. We therefore spent months perfecting the optimal formulation that maximizes the effect of PAP while maintaining its stability. By adding other supporting ingredients for remineralization and strengthening teeth, such as potassium citrate and hydroxyapatite, we developed the PAP+ formula, which effectively whitens teeth—without any unwanted side effects.
