Clinically reviewed by David Hanna, RDH — Registered Dental Hygienist

Clinical Indications & Contraindications

Indications

  • Moderate staining where faster lift is desired without going to maximum strength
  • Patients who tolerated 25% previously and want more pronounced results

Contraindications & Cautions

  • Active oral pathology; unresolved hypersensitivity
  • Inadequate isolation capability — barrier is strongly recommended

Mechanism of Action

35% HP increases reactive oxygen availability and diffusion rate, enabling a quicker oxidation of chromogens. Outcomes depend on isolation quality and cycle control.

Step‑by‑Step Protocol (35% HP)

1) Preparation

  • Baseline shade, photos, consent
  • Dry field; lip/cheek retractors

2) Isolation

  • Barrier recommended around gingival margins and exposed cervical areas

3) Application

  • 1–2 mm even layer; avoid soft tissue
  • Fresh ribbon each cycle

4) Timing

  • 1–2 cycles × 15–20 minutes; mid‑cycle agitation

5) Finish

  • Suction, rinse; inspect tissues

6) Aftercare

  • 48‑hour white diet; consider desensitizer

Sensitivity Risk & Mitigation

Risk Factors

  • Exposed dentin; previous post‑op sensitivity

Mitigation

  • Strict isolation; reduce to 1 cycle if needed
  • Use desensitizer; reinforce aftercare

Case Scenarios

Moderate staining

1–2 cycles × 15–20 min. If plateaued, consider finishing with 38% HP.

Time‑limited sessions

Single cycle; add recall at 3–6 months with 25% HP maintenance.

Troubleshooting & Common Pitfalls

  • Soft‑tissue blanching: Stop, irrigate, re‑isolate; reinforce barrier.
  • Limited lift after 1 cycle: Add a second cycle or consider an incremental finish at 38%.

Storage, Handling & Compliance

Storage

  • Cool, dry; avoid heat/sun
  • Check expiry and rotate stock

Compliance

  • Professional use; follow labeling and local regs
  • Consent and documentation recommended

Pricing, Packaging & Positioning

Positioning

“Faster lift, controlled comfort” — a premium above 25% without going to max.
