WTD!™ PAP Whitening Strip

Sensitivity-Free PAP Teeth Whitening Strips

Includes 14 individually packaged & on-the-go whitening treatments


Traditional whitening strips use hydrogen peroxide, which can cause sensitivity and may irritate gums.

Instead, WTD! PAP Whitening Strips are peroxide-free and use the safe and clinically-proven active whitening ingredient PAP (Phthalimidoperoxycaproic Acid). PAP works similarly to peroxide, but it breaks down only the stains & discoloration, and doesn’t cause any sensitivity, irritation, or pain.

PAP: Phthalimidoperoxycaproic acid (PAP) stands as a clinically proven powerhouse, offering remarkable teeth whitening results while ensuring zero sensitivity or gum irritation.

Derived from eggshells containing natural balanced minerals from the shells, and is very similar to the components of human bone and teeth, with a high level of biocompatibility.

Potassium Citrate: Provides benefits such as reducing tooth sensitivity, neutralizing acidity, enhancing the whitening experience, and improving treatment compliance.


Pros of PAP teeth whitening:

  • Effective Whitening: PAP has been clinically proven to provide effective teeth whitening results by breaking down stains and discolorations on the tooth surface.

  • Reduced Sensitivity: PAP is known for its low potential to cause tooth sensitivity compared to hydrogen peroxide, making it a suitable option for individuals with sensitive teeth.

  • Gentler on Gums: PAP-based formulas are generally considered to be less likely to cause gum irritation or inflammation compared to hydrogen peroxide-based formulas.

Cons of PAP teeth whitening:

  • Limited Availability: PAP-based teeth whitening formulas may not be as widely available as hydrogen peroxide-based formulas, as hydrogen peroxide has been the more commonly used active ingredient in commercial whitening products.

  • Potentially Slower Results: While effective, PAP-based formulas may require longer treatment durations or repeated applications to achieve desired whitening results compared to hydrogen peroxide-based formulas.


  • Superior Teeth Whitening Performance – You’ll start to see a whiter smile after 3 days with full results in 14 days or less. When applied to your teeth, each strip tightly adheres to the tooth surface and allows active ingredient PAP to be in contact with the tooth’s structure to provide effective teeth whitening , as well as reducing pre-existing sensitivity.

  • Long-Lasting Antibacterial – PAP and menthol are both powerful antibacterial agents.

  • Anti-Plaque – Sodium Tripolyphospate has been clinically proven to reduce & prevent plaque formation.

  • No Discomfort or Sensitivity – As the key whitening ingredient in our Teeth Whitening Strips, PAP is scientifically proven to be a safe alternative to peroxide. It has no negative side effects which allows it to be used more frequently than peroxide-based whitening strips, and can effectively whiten teeth without any pain or sensitivity. WTD!’s 3D-Form Technology guarantees adhesion and no slip, you can freely talk and drink water while whitening.
