Dentists diagnose, prevent, and treat problems affecting the teeth, gums, and mouth. They perform examinations, fillings, extractions, and other procedures, provide preventive care, and educate patients about oral health. Modern dentistry uses digital X-rays, 3D imaging, CAD/CAM technology, lasers, computerized records, and increasingly AI-assisted diagnostic tools.
A four-year Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD) program is required after completing the university-level courses required for admission. Graduates must also complete the required licensing examinations and professional registration before practicing as dentists.
Dentists work mainly in dental offices and clinics, with others working in hospitals, public health, universities, or specialty practices. Many dentists own or operate their own practices. The work involves close patient contact, precise hand skills, specialized equipment, and long periods of concentration. Dentists may also use digital imaging, computer-aided design, electronic records, and other advanced technology.
Dentistry should continue to have steady demand as people live longer and retain more of their natural teeth, increasing the need for preventive, restorative, and ongoing dental care. Demand is also supported by oral disease, dental injuries, and cosmetic and restorative procedures. Technology will continue to change the profession through digital imaging, 3D printing, CAD/CAM systems, lasers, robotics, and AI-supported diagnosis and treatment planning. Current workforce projections indicate steady employment rather than rapid growth, while retirements and the need to replace dentists will continue creating opportunities.
