Some work evenings and weekends to meet their patients' needs. Most full-time dentists work about 40 hours a week, but others work more. Initially, dentists may work more hours as they establish their practice. Experienced dentists often work fewer hours. A considerable number continue in part-time practice well beyond the usual retirement age.
Some dentists have partners, and a few work for other dentists as associate dentists.
About 9 out of 10 dentists are in private practice. Others work in private and public hospitals and clinics, the Federal Government, and in dental research. In most States, a candidate must graduate from a dental school accredited by the American Dental Association's Commission on Dental Accreditation, and pass written and practical examinations to qualify for a license. Candidates may fulfill the written part of the State licensing by passing the National Board Dental Examinations. Individual States or regional testing agencies give the written or practical examinations.
