Dentistry is a healthcare profession focused on oral health. Dentists diagnose, prevent, and treat various dental and oral conditions, such as cavities, gum disease, and oral injuries. They perform dental procedures like cleanings, fillings, extractions, and root canals. Dentists also provide oral health education to patients. A career in dentistry requires extensive education, typically a bachelor's degree followed by dental school, and the acquisition of a professional license. Dentists often run their private practices or work in dental clinics, hospitals, or research institutions. It's a rewarding career that combines medical knowledge, manual dexterity, and patient care to improve people's oral health.
