Dentists are different from the medical doctors in terms of their practice and education. Medical doctors study and maintain the health of the entire body, whereas dentists only study the oral cavity. In terms of education, doctors are required to finish 4 years of bachelor studies plus an additional 4 years of medical studies. On the other hand, dentists need only to finish the required courses plus an internship or practice period before they are allowed to have their license. This takes a time of at least 5 years. This, however, does not mean that dentists are inferior to medical doctors. Dentistry is more of a specialization and should therefore be treated as such.
