Get the popular PAP+ teeth-whitening gel for highly effective whitening. The natural, gentle action works directly on the teeth without irritating enamel or gums. Clinically tested – with no teeth sensitivity. With its special PAP+ formula, it removes up to 76% more stains than conventional bleaching gels.
A major benefit of PAP+ whitening gel is the protection it provides for your teeth and enamel. Carefully chosen ingredients work together to protect your teeth throughout the whitening process, ensuring a gentle and safe application.
DiamondSmile delights over 575.000+ satisfied customers worldwide.
The main active ingredient in PAP+ whitening gel also gives PAP+ its name (phthalimidoperoxycaproic acid). This ingredient lifts unwanted discolouration from your teeth and is suitable even for sensitive teeth.
PAP+ not only brightens your teeth, it also extends the whitening effect of our other products. Additional ingredients help keep your mouth hydrated over time. That’s not only good for oral health, but also one of the best ways to prevent bad breath.

What do I need the refill gel for?
You need the refill gel when the teeth-whitening gel from your bleaching kit is empty. It’s always a good idea to purchase a refill set along with the bleaching kit to carry out a longer and more sustainable whitening regimen.
How does the at-home teeth-whitening set work?
Discoloration and stains on the tooth are removed naturally through oxidation on the enamel, and the tooth is lightened.
How can the bleaching effect be improved?
Improve and prolong the bleaching effect with our activated charcoal. Using it before bleaching makes teeth even brighter, as the activated charcoal can already remove coarse discoloration.
How many applications does the gel provide?
Per gel syringe, 3–4 applications can be carried out. We always recommend purchasing a refill gel with the teeth-whitening set to enable long-term treatment.
How long do teeth stay white after use?
The whitening effect of the bleaching kit usually lasts 1 to 2 years. After use, you should continue to take good care of your teeth.
Is the bleaching kit safe?
The DiamondSmile bleaching kit has been approved, tested and certified in Germany (certificates: CE, FDA, ISO, MSDS). We also recommend visiting your dentist for a professional cleaning and to get advice on whether your teeth are suitable for a home bleaching kit.
Is teeth whitening at the dentist better?
Dentists usually use the active ingredient hydrogen peroxide or carbamide peroxide. Both can strongly affect tooth enamel and gums and cause pain.
Will the bleaching kit even work for me?
The active ingredients in our gel in the bleaching kit are designed to act directly on the tooth regardless of the condition of the teeth.
Why do we work without peroxides?
Peroxides are highly acidic and can attack your teeth, enamel and gums. This usually leads to tooth sensitivity and can cause irritation. For this reason, we do not use peroxides in our products.
What is PAP+?
The main active ingredient also gives PAP+ its name (Phthalimidoperoxycaproicacid). This active ingredient lightens unwanted discoloration and stains on your teeth.
Does PAP+ hurt?
The ingredient PAP+ is also suitable for sensitive teeth, so you don’t need to worry when using it.
How long does it take until my teeth are whiter?
In most cases you should see noticeable results after a week of regular use. During this time, the activated charcoal helps remove external stains from the surface of the teeth.
How long will my result last?
With correct use of our teeth-whitening set in combination with our other teeth-whitening products, your white smile typically lasts up to two years. If you frequently consume indulgences such as coffee, soft drinks, tannin-rich tea, tobacco, etc., your teeth will gradually darken again. That’s no problem, because you can simply order new teeth-whitening gel for your bleaching kit.
What shade can my teeth achieve?
The result depends on the degree of discoloration and your teeth’s natural color. You can see your first results after the first applications. With correct use and proper oral hygiene, teeth can become up to 12 shades lighter. Use our activated charcoal before whitening to achieve maximum results.
How long do teeth stay white after use?
The whitening effect of the bleaching kit usually lasts 1 to 2 years. After use, you should continue to take good care of your teeth. It is also advisable to limit staining foods and drinks such as coffee and tea. Smoking should also be avoided to ensure lasting results. If the effect fades, you can always get new teeth-whitening gel for your bleaching kit from us.
