Abstract
<jats:p>Short-form video content has shed light on health communication, and public dental health is at a crossroads. This chapter introduces TikTok and GenAI as a two-engine system to enhance oral health worldwide. This study proposes a three-part strategy to address dental misinformation and DIY dental care: (1) AI-Based Content Engineering, where AI-powered LLMs and synthetic avatars deliver effective and non-intimidating education; (2) Algorithm Implementation, where Gen Z and Alpha demographics are targeted with local clinical access through Gen Z and Alpha-friendly edutainment; and (3) Targeted Dental Public Health. GenAI lowers production obstacles, enabling practitioners to maintain a high-rate evidence-based engagement cycle. This synergy increases the public's Knowledge, Attitudes, and Practices (KAP) and introduces Digital Care Ethics, which promotes clinically responsible, technologically enhanced oral health services.</jats:p>
