The practice of dentistry in the United States is overseen by several agencies including the American Dental Association, the Commission on Dental Accreditation and the regional boards. Ultimate licensure is the responsibility of individual states. There are roughly 190,000 practicing dentists in the United States.
Dental education
In order to be accepted to an American dental school, most candidates must possess at least a bachelor's degree as well as the pre-requisite courses. The first 2 years of dental school consist mostly of didactic education as well as simulation courses. The last two years generally involve direct patient care under supervision. There tends to be much overlap in most schools' curricula; the didactic years may have some clinical components, while the last two years still have significant didactic coursework. During dental school, students must take and successfully pass Part I and Part II of the National Board Dental Examination, which are administered by the ADA. Part I is usually taken after the second year of dental school, while Part II is usually taken sometime in the fourth year. The cost of attending dental school is high; most newly graduated dentists have borrowed US$200,000 or more in student loans and other debts to pay for their education.
Licensure
Accredited programs
The first step in practicing dentistry in the United States is graduating from an accredited dental degree program in the United States and Canada. The graduates of Australian dental schools cannot be licensed in the United States. The reciprocity agreement between CDAC and Australia does not extend to the United States and the Commission on Dental Accreditation. The reciprocity agreement that CODA has with CDAC only covers Canadian programs. CODA does have policies and procedures in place for accrediting established international predoctoral education programs.
Until the late 20th century, most of dentistry was paid directly by patients. Today funding for dentistry includes self-payment, private insurance, employer-sponsored insurance, Medicaid and SCHIP.
Criticisms
Evidence since 1977 has shown that seeing a dentist every six months, as is standard in the United States, is not associated with improved dental or oral health. Some of the largest dentistry companies in the United States have been subject to class-action lawsuits for their fraudulent practices,
