Dental advertising in Hong Kong falls under the same Undesirable Medical Advertisements Ordinance (Cap. 231) negative list that governs medical and aesthetic advertising generally — dentistry does not get a lighter carve-out. Practices still leaning on unrestricted before/after smile photos or absolute-outcome claims are advertising in a way the ordinance's negative list already prohibits, enforced criminally. Any campaign collecting personal data — a booking form, a WhatsApp enquiry — separately sits under the Personal Data (Privacy) Ordinance (PDPO), requiring informed consent and an opt-out before that data is used for marketing.
Invisalign and cosmetic dentistry carry Hong Kong's highest per-case values in the category, which is exactly why compliance discipline matters here — a pulled campaign or enforcement action costs far more in lost bookings than the creative rework would have. We build the funnel around what the ordinance actually allows: education, credentials and a genuine consultation pathway, applying the same discipline behind our Malaysia dental clinic marketing work (MDC) to Hong Kong's own regime.
