Dentistry is an important branch of healthcare that focuses on the diagnosis, prevention and treatment of issues related to oral health. One of the primary aspects of dentistry is preventive care. Regular dental check-ups, cleanings, and oral examinations help in detecting early signs of dental problems such as tooth decay, gum disease and oral cancer. Restorative dentistry is another fundamental aspect of the field. It involves repairing and restoring damaged or missing teeth.

It also encompasses specialized fields such as orthodontics, which corrects misaligned teeth and bite irregularities, and endodontics, which involves root canal treatments to save infected teeth.
