They don’t perform root canals or fill cavities, but their work directly safeguards patients’ long-term oral health. As people’s focus on preventive healthcare surges, this once-overlooked role has become a "high-value asset" in the medical field

1. More Than Just "Teeth Cleaners": Core Pillar of the Dental Team

Dental Hygienists are far beyond "professional teeth cleaners"—they’re preventive oral health experts. Their core responsibility is to stop oral diseases before they start, shouldering key tasks in the dental care system:

  • Comprehensive oral assessment: Screen for dental caries, periodontal disease and oral cancer signs; accurately analyze X-rays 🔍
  • Professional periodontal care: Remove plaque, tartar and other debris in hard-to-brush areas via ultrasonic scaling 🧹
  • Preventive intervention: Fluoride application, pit and fissure sealing for children, and developing personalized caries prevention plans
  • Unlike dentists who focus on treatment, hygienists specialize in prevention—filling the critical gap between "treatment" and "health maintenance."
