HP — Hydrogen Peroxide
Speed: Fastest in-office change.
Sensitivity: Strength-dependent (start gentler).
Best for: Chairside lift with LED/laser.
HP vs CP vs PAP+: Professional Whitening Gels Compared (Indications & Chair Flow)
Professional Whitening Guide
HP vs CP vs PAP+: Indications & Chair Flow
Compare chemistries, pick strengths, plan isolation and light settings, and set maintenance for lasting results.
Executive summary: when to choose HP, CP, or PAP+
HP (Hydrogen Peroxide) — fastest chairside lift. Choose strength by tolerance and stain: 16%, 25%, 35%, 38%, 44%.
CP (Carbamide Peroxide) — slower release; great for spot touch-ups & compliant at-home plans via 44% CP Pen.
PAP+ — peroxide-free; comfort-forward for sensitivity-prone clients: 12% PAP+.
Combine a single in-office HP visit for immediate lift with CP or PAP+ for maintenance.
CP — Carbamide Peroxide
Speed: Slower, user-paced.
Sensitivity: Moderate; targeted areas.
Best for: At-home maintenance / spot fixes.
Format: 44% CP Pen
PAP+ — Peroxide-Free
Speed: Gentle cosmetic brightening.
Sensitivity: Lowest; comfort-forward.
Best for: Sensitive clients or cautious plans.
Strength: 12% PAP+

Pre-Tx & Isolation
- Shade baseline, photos, sensitivity history.
- Gingival barrier + HVE for ≥35% HP; dry field; clean margins.
Placement & Timing
- Apply even 1–2 mm layer; avoid soft tissue; agitate mid-cycle.
- 15–20 min per cycle; 1–3 cycles per severity & tolerance.
Sensitivity management (Pre-Tx, Intra-Op, Post-Care)
LED/Laser parameters
Use lamp IFU for exposure time, distance, and cycles.
- HP: quicker response; strength-based cycles.
- PAP+: gentle pacing; LED improves workflow consistency.
- CP: reserve for at-home or spot scenarios.
Storage & QA
- Cool storage; refrigerate if label specifies.
- Record batch/lot per client for traceability.
- Clinic-ready syringes (e.g., 5 mL) streamline setup.
