Dentistry, more appropriately "dental medicine", is the art and science of prevention, diagnosis, and treatment of conditions, diseases, and disorders of the oral cavity, the maxillofacial region, and its associated structures as it relates to human beings. While the work of dentists is often surgical in nature, dentists can and do treat many diseases of the oral cavity and face chemotherapeutically (i.e. with prescribed medicines).



A dentist is a doctor, qualified to practice dentistry after graduating with a degree of either Doctor of Dental Surgery (DDS), Doctor of Dental Medicine (DMD), Bachelor of Dentistry (BDent), Bachelor of Dental Science (BDSc), or Bachelor of Dental Surgery (BDS) or (B.Ch.D). In most western countries, to become a qualified dentist one must usually complete at least 4 years of postgraduate study. Generally, 2 years of clinical experience working with patients in an educational setting are required.



The first dental school, the Baltimore College of Dental Surgery, opened in Baltimore, Maryland in 1840. Harvard Dental School was the first dental school to affiliate with a university in 1867 (renamed Harvard School of Dental Medicine in 1940.)
