A dentist is a healthcare professional specializing in the diagnosis, treatment, and prevention of oral health issues, particularly those related to teeth, gums, and the mouth. They are responsible for addressing common dental concerns such as cavities, gum disease, and tooth decay, as well as performing restorative treatments like fillings, crowns, bridges, and more advanced procedures like root canals and extractions.

Dentists also play a key role in preventive care by educating patients on proper oral hygiene, such as brushing and flossing techniques, and providing routine check-ups to maintain optimal oral health. In addition to general dentistry, some dentists specialize in areas such as orthodontics (braces and alignment), periodontics (gum care), or oral surgery (which involves more complex procedures like tooth extractions, implants, or surgeries related to the mouth and jaws).

To become a dentist, one typically must complete a dental school program after obtaining a bachelor’s degree, followed by licensing exams, which vary by country.
