Whitening Strips - PAP + nHA + Xylitol 14 Strips · 7 Treatments

Hydrogen peroxide whitens by penetrating enamel and oxidising stain compounds inside the tooth. It is effective but frequently causes sensitivity and can weaken enamel structure with repeated use. PAP (Phthalimidoperoxycaproic Acid) targets stain chromophores at the tooth surface without the same degree of enamel penetration. The visible whitening result is comparable. The sensitivity side effect is significantly reduced. nHA in the formula also supports enamel mineral balance during the process. Peroxide-free was not a compromise was the point.

WPF stands for Whitening Performance Formula MasterMedi's formulation designation for this product's combination of PAP, nHA, and Xylitol. It indicates that the formula is designed specifically for whitening performance (PAP) while simultaneously protecting enamel (nHA) and supporting the oral environment (Xylitol). Not a marketing term the three ingredients each do a specific clinical job.

Nano Hydroxyapatite particles are small enough to fill micro-abrasions in the enamel surface. During a whitening session, even gentle whitening can temporarily affect enamel surface integrity. nHA bonds to those micro-abrasions, replenishing mineral structure and reducing the pathway for sensitivity signals. It also contributes to surface smoothness, which improves light reflection a whiter-looking tooth is partly a smoother tooth.

PAP whitening is gradual it lifts surface stains progressively with each session rather than in one aggressive treatment. Most users see noticeable improvement within 7 days of daily use. Full treatment over 21 days produces more significant results. This is intentional: gradual whitening is gentler on enamel and more sustainable than a single high-intensity session.

Yes. The peroxide-free formula means the primary cause of whitening-induced sensitivity is removed. nHA in the formula actively supports enamel mineral balance during the session, which further reduces sensitivity pathways. If you have existing dentinal hypersensitivity or have recently had dental work, consult your dentist before starting a whitening treatment but the formulation is designed with sensitivity in mind.

The toothpaste is a daily maintenance product its PAP is formulated for brushing contact time and works alongside nHA, Xylitol, and Probiotic for daily oral care. The strips are a targeted whitening treatment a 30-minute daily session with a higher-contact PAP delivery directly on the tooth surface. The toothpaste maintains. The strips whiten. Both use PAP and nHA, but the delivery mechanism and treatment intensity are different. Using both is the complete approach.

The 42-strip box contains 21 treatments one upper strip and one lower strip per treatment, used daily. The 14-strip box contains 7 treatments. One treatment = 30 minutes = one upper and one lower strip. Both sizes contain the same formula at the same concentration.

Yes. Apply to dry, brushed teeth for best adhesion and best results. A clean tooth surface with no toothpaste film allows the no-slip adhesive to grip properly and allows PAP direct contact with the stained enamel surface. Brush, rinse, dry slightly, then apply. Do not apply to wet or saliva-coated teeth.

No. The strips are a closed-mouth treatment. Eating or drinking during the 30 minutes disrupts adhesion and dilutes the formula. Water is also not recommended during wear it can compromise the no-slip grip. Remove strips after 30 minutes, then eat and drink normally.

Daily use for 7–21 days is the recommended treatment cycle. After the treatment period, maintenance use 2–3 times per week is appropriate. The peroxide-free formula and nHA enamel support make this suitable for daily use without the enamel depletion risks associated with daily peroxide-based whitening.

Step One: UV Smart Flosser -cremoves debris between teeth and below the gumline. Step Two: Tongue Scraper -cremoves bacterial coating from the tongue surface. Step Three: Electric Toothbrush - brushes all tooth surfaces. Step Four: Mouthwash/Rinse -final cleanse and oral balance. Step Five: these strips. The routine is designed so that Step Five operates on the cleanest possible tooth surface - the four preceding steps prepare the mouth for whitening to work at full effectiveness.
