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.
