Prolong the whiteness of your teeth with the new PAP+ dental whitening gel. Through oxidation, the PAP+ gel removes tooth and enamel discoloration. The oxidation process is gentle on both teeth and gums, so there’s no need to worry if you have sensitive teeth. With continued use, it also neutralizes new discoloration, meaning its whitening effect lasts even longer.
How does it work? Clean your teeth, attach the nozzle to one of the adapters, fill the nozzle with PAP+ gel, whiten your teeth for 10 to 30 minutes, and then rinse your mouth.
Get the popular PAP+ teeth whitening kit now for highly effective whitening. Its natural and gentle whitening formula works directly on the teeth without irritating enamel or gums. Clinically tested, it is suitable for people with sensitive teeth.
The main active ingredient in the PAP+ whitening gel is the source of its name—PAP+ (phthalimidoperoxycaproic acid). This active ingredient lightens unwanted tooth discoloration. The PAP+ active ingredient not only ensures brighter teeth but also prolongs the whitening effect of our other products. Additional ingredients provide long-lasting oral hydration, benefiting overall oral health and helping to prevent bad breath.

Is whitening at the dentist better?
Both at-home whitening kits and professional dental whitening can provide similar results. The effectiveness of glycerin-based whitening depends mainly on two factors: the concentration of glycerin and the contact time with the teeth. DiamondSmile uses the maximum amount of glycerin allowed in Germany in its Whitening Kit for optimal results.
Dentists often use hydrogen peroxide or carbamide peroxide, which can seriously damage enamel and gums and cause pain.
How long do teeth stay white after use?
The whitening effect of the kit usually lasts 1–2 years. After treatment, continue caring for your teeth properly. It’s also advisable to limit staining foods such as coffee and tea and avoid smoking for long-lasting results. If the effect fades, you can always get a new whitening gel refill from us.
How does the at-home whitening kit work?
The active ingredient, glycerin, penetrates the enamel through LED power activation technology. The oxygen molecules in the whitening agent react with discolored molecules in the teeth, breaking them down and revealing your natural white color.
Boost and prolong the whitening effect with our activated charcoal. Using it before whitening removes coarse discoloration, making teeth appear even brighter. Regular weekly use of activated charcoal helps maintain your results.
Is the whitening kit safe?
The DiamondSmile Whitening Kit is approved, tested, and certified in Germany (CE, FDA, ISO, MSDS). The active ingredient concentration is chosen to ensure maximum whitening results without damaging enamel. For best results, follow the included instructions. It’s also advisable to get a professional cleaning and consultation from your dentist before starting whitening treatments at home.
How do I use the kit?
To use the whitening kit correctly, follow these steps:
1. Brush your teeth thoroughly with toothpaste.
2. Remove the thin plastic disk between the batteries.
3. Connect the mouth tray to the LED light.
4. Apply 1/4 of the gel to the top and 1/4 to the bottom of the tray.
5. Place it in your mouth and turn on the light.
6. Wait 10–20 minutes before turning off the light.
7. Rinse your mouth with warm water.
8. Smile!
Are batteries included?
The LED light uses button batteries (CR2450), which are included. For safety, a thin plastic tab separates the battery and button to prevent contact during shipping.
How does the whitening set work?
Our whitening kit uses a professional-grade formula and advanced LED technology to remove stains and discoloration. The combination of gel and light whitens teeth effectively and gently.
Is the whitening kit safe for my teeth?
Yes, the whitening kit is safe when used as directed. The formula is gentle on teeth and enamel while effectively removing stains. Always follow the recommended application time and frequency for best results and to protect tooth health.
Can I use the whitening kit on sensitive teeth?
Yes, the kit is also suitable for sensitive teeth. Its gentle formula minimizes discomfort and sensitivity. However, if you experience severe sensitivity, consult your dentist before using.
What is PAP+?
The main active ingredient, PAP+ (Phthalimidoperoxycaproic Acid), helps lighten discoloration and remove unwanted stains from teeth.
Does PAP+ cause pain?
PAP+ is gentle enough for sensitive teeth, so there’s no need to worry about discomfort when using it.
How long will it take for my teeth to whiten?
Most users see visible results after one week of regular use. During this time, the activated charcoal helps remove external stains from the tooth surface.
How long will my results last?
When used correctly along with our other whitening products, your white smile can last up to two years. Regular consumption of coffee, tea, or tobacco may lead to new stains, but you can easily refresh your results with a new whitening gel refill.
What shade can my teeth achieve?
The result depends on the level of discoloration and your natural tooth color. After the first few applications, you’ll see visible improvement. With consistent care, teeth can appear up to 12 shades lighter. For optimal results, use our activated charcoal before whitening.
How long do teeth stay white after application?
The whitening effect usually lasts between 1 and 2 years. Continue maintaining oral hygiene and limit staining foods like coffee and tea. Avoid smoking to ensure long-lasting results. If the whitening fades, simply order a new gel refill from us.
Why do we work without peroxides?
Peroxides are very acidic and can damage teeth, enamel, and gums. This often causes hypersensitivity and irritation. For this reason, we do not use peroxides in our products.
