“Hismile toothpaste provides a permanent white smile.”
HIGH CONFIDENCE
TL;DR ·Hismile removes surface stains but cannot permanently change the internal color of tooth enamel.
Evidence from multiple sources indicates that Hismile products do not provide a permanent white smile. High-credibility research and dental evaluations clarify that Hismile's peroxide-free formula, which utilizes PAP (Phthalimidoperoxycaproic acid), primarily targets surface stains rather than altering the internal color of the teeth . Scientific studies show that the greatest effect achieved by such over-the-counter products is the lifting of extrinsic stains, and only hydrogen peroxide—which Hismile avoids to reduce sensitivity—can further whiten the enamel itself . Furthermore, dental professionals note that because the product targets surface-level discoloration, results are temporary and subject to new staining from food and lifestyle factors . The National Advertising Division has also challenged Hismile's marketing claims regarding its effectiveness and transparency . While some users report significant shade improvements after multiple sessions , no evidence supports the claim that these results are permanent .
