Dentistry is a branch of medicine focused on the diagnosis, prevention, and treatment of conditions related to the teeth, gums, and mouth. Dentists, the professionals who practice dentistry, perform various procedures such as cleanings, fillings, and extractions to maintain oral health. They also educate patients on proper dental hygiene practices. In addition to general dentistry, there are specialized fields like orthodontics, which deals with correcting misaligned teeth, and periodontics, which focuses on gum diseases. Regular visits to a dentist are essential for preventing dental issues and ensuring overall health, as oral health is closely linked to overall well-being.
