Education Requirements

There are no formal education requirements for entering a career in dental assisting. Some assistants have a high school diploma and only receive on-the-job training; however, postsecondary dental assisting programs offer more comprehensive career training. According to the U.S. Bureau of Labor Statistics, there were almost 300 dental assisting education programs approved by the Commission on Dental Accreditation (CODA) in 2015 (

Dental assisting programs are typically 1-year diploma or certificate programs. These programs tend to focus solely on technical training through classroom, laboratory and clinical instruction. Courses may include dental materials, radiology, chairside assisting, dental office administration and biodental science. Some community colleges and vocational schools also offer 2-year associate's degree programs, which combine general education, technical training and more extensive clinical practicums.


Some states allow dental assistants to perform all duties assigned by a dentist, while in other states, they must obtain licensure or registration to perform certain duties. Licensure requirements vary by state, but may include completing an accredited postsecondary program. Licensure candidates may also be required to pass a written or practical exam. Dental assistants often maintain licensure by earning continuing education at state-specified intervals.


The Dental Assisting National Board offers the Certified Dental Assistant (CDA®) certification, which was recognized or required by 38 states and the District of Columbia as of 2014 ( To be eligible to take the CDA® exam, applicants must hold a current CPR certification and meet one of the following qualifications:

  • have graduated from an accredited dental assisting/dental hygiene program,
  • have a high school diploma, or equivalent, and a minimum of 3,500 hours of approved work experience, OR
  • have previously held DANB CDA® status, or have graduated from an accredited DDS or DMD program, or graduated from a dental degree program abroad.

Employment Outlook and Salary Information

According to the U.S. Bureau of Labor Statistics (BLS), employment opportunities in the field are expected to grow much faster than the national average from 2018-2028. In May 2018, the BLS reported that professionals in the 90th percentile or higher earned $54,800 or more per year, whereas the bottom 10th percentile earned $26,940 or less per year.

It's important to consider the job duties, required training and projected job growth when deciding if a career as a dental assistant might be right for you. Understanding whether or not you will have to acquire state licensure and/or certification prior to working as a dental assistant is a good first step in this process.
