Dentist
Overview
A dentist (치과의사, 齒科醫師, Dentist) is a medical professional who prevents, diagnoses, and treats diseases of the oral and maxillofacial (口腔顎顔面) region, including the teeth, gums, jawbone, and oral mucosa. Dentists handle a wide range of care, from treating common oral conditions such as cavities and gum disease to implants, orthodontics, and oral and maxillofacial surgery. As awareness grows that oral health is closely linked to overall health, their role is becoming increasingly important.

Definition and Role
A dentist is a medical professional who holds a separate professional license distinct from that of a physician under the Medical Service Act. Beyond simply extracting or filling teeth, dentists also serve as a primary screening channel, identifying signs of systemic diseases such as diabetes, cardiovascular disease, and osteoporosis through the condition of the oral cavity and referring patients accordingly. They also contribute to improving quality of life by restoring masticatory (chewing) function, pronunciation, and esthetic function.
Areas of Practice
Dental care is divided into detailed specialties.
- Restorative Dentistry: Cavity treatment (resin, amalgam, inlay), nerve treatment (root canal therapy)
- Prosthodontics: Crowns, bridges, dentures, implants
- Orthodontics: Correction of malocclusion, clear aligners, dentofacial orthopedic treatment
- Oral and Maxillofacial Surgery: Wisdom tooth extraction, orthognathic surgery, temporomandibular joint disorders, oral tumors
- Periodontics: Management of gum disease (periodontitis), scaling, gum surgery
- Pediatric Dentistry: Primary tooth management, preventive care, habit correction
- Preventive Dentistry: Fluoride application, sealants, oral health education
Education and Licensure
In Korea, one must graduate from a dental school (six-year program) or a graduate school of dentistry (four-year program, for bachelor's degree holders) and pass the national dental licensing examination to obtain a license. Afterward, through internship and residency programs, dentists can obtain specialist qualifications in prosthodontics, orthodontics, oral and maxillofacial surgery, periodontics, and other fields, and the specialist system has been established in stages since the 2000s. After graduation, a variety of career paths are available, including opening a private practice, working at a university hospital, research positions, and public health roles (public health centers, military medical officers).
Practice Environment
Most dentists work in private clinics providing primary care, while dentists at university dental hospitals or general hospital dental departments handle severe and rare diseases and specialty surgeries. Recently, the practice environment is changing significantly with the introduction of digital equipment.
Latest Trends
Digital Dentistry
As intraoral scanners, CBCT (three-dimensional imaging), and CAD/CAM milling equipment have become widespread, same-day prosthetic fabrication without impression-taking has become possible. Surgical guides and custom implants produced by 3D printing are increasing precision, and AI-based image-reading software is being used to automatically detect cavities and bone loss on X-rays.
AI and Clinical Assistance
In 2024–2025, the use of generative AI for automating clinical records, patient consultation chatbots, and orthodontic treatment planning simulations is spreading. However, the principle is emphasized that AI is only an auxiliary tool, and final diagnosis and responsibility rest with the dentist.
Population Aging and Changing Demand
While demand for implants and dentures is surging due to population aging, oral care in elderly care facilities, responses to swallowing (dysphagia) disorders, and research on the link between dementia and oral health are becoming more active. In addition, as the cosmetic dentistry market (veneers, teeth whitening) grows, controversies over medical advertising regulations and overtreatment are also coming to the fore.
Institutions and Workforce
Discussion continues over the number of dentists being produced and the saturation of private practices, and major issues include the legal scope of telemedicine and remote collaboration, as well as the adjustment of task boundaries among personnel such as dental hygienists. Amid discussions on expanding essential medical personnel, the expansion of oral health insurance coverage (scaling, dentures for the elderly, etc.) is proceeding in stages.
