Dentistry, also known as Dental and Oral Medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity. Dentists diagnose and treat dental issues and help patients develop better oral hygiene regimens. They clean teeth, correct bite issues, perform surgeries and extractions, and perform other duties to ensure that the teeth and mouth are healthy.
