Clinically reviewed by David Hanna, RDH — Registered Dental Hygienist
Clinical Indications & Contraindications
Indications
Clients with sensitivity history or peroxide aversion
Mild extrinsic staining and mid‑cycle maintenance between HP sessions
Intro whitening for first‑time patients; cosmetic studio add‑on
Contraindications & Cautions
Active caries, cracks, or open lesions; defer until resolved
Extensive restorative work in the esthetic zone (enamel only responds)
Unrealistic expectations for single‑visit shade jumps; set clear goals
Mechanism of Action (Peroxide‑Free)
PAP+ (phthalimidoperoxycaproic acid) whitens via a non‑peroxide oxidative pathway with adjunctive enamel‑friendly ingredients. While lift is gentler than HP, the sensitivity profile is favorable, making PAP+ ideal for cautious starts and maintenance.
