Dentists are healthcare professionals who specialize in oral health. They diagnose and treat issues related to teeth, gums, and the mouth. Common procedures performed by dentists include cleanings, fillings, extractions, and root canals. They also provide guidance on proper dental hygiene and preventive care to help maintain healthy teeth and gums. To become a dentist, individuals must complete a dental degree, which typically requires several years of education and training. Dentists often work in private practices, but they can also be found in hospitals or community health centers. They may collaborate with other professionals, such as dental hygienists and orthodontists, to provide comprehensive care.
