Dental Assistant Requirements in Maryland: Dental Assistant School in MD Can Go a Long Way

Maryland does not set standards for dental assistants who perform the most basic duties; this is left to the discretion of the individual dentist/ employer. Many duties, however, are reserved for individuals who have completed state-mandated training and examination.

A person may be qualified to perform one expanded function or many. Maryland has a state-specific examination process for some expanded functions. Examinations are administered by the Dental Assistant National Board (DANB).

Dental assistants who carry out expanded functions will need varying amounts of formal education. Dental assistants may also find formal education useful for breaking into the field. Maryland schools offer general chairside duties as well as expanded functions.
