Dentistry is a field of healthcare that focuses on the diagnosis, prevention, and treatment of diseases and conditions affecting the teeth, gums, and oral cavity. Dentists are trained to provide a range of services, including routine cleanings, fillings, root canals, and extractions, as well as cosmetic procedures such as teeth whitening and veneers. They also play a crucial role in educating patients about good oral hygiene practices to maintain overall dental health. Advances in technology and research have led to the development of new techniques and materials that have improved the quality and effectiveness of dental care. Dentistry is an important part of overall health and well-being, as oral health is closely linked to systemic health and can impact various aspects of a person's life.
