Dental assistants perform clinical and administrative support functions within a dental office and are able to assume greater responsibilities with additional education and certifications.
Dental assistants play a support role and perform general office duties within a private dental office or the dental department of healthcare facilities. The responsibilities of dental assistants are diverse as they become involved with direct patient care, laboratory testing, as well as routine clerical tasks.
General Responsibilities of Dental Assistants:
- Prepare patients for dental examination and arrange instruments.
- Provide chair-side assistance to the dentist during examinations (e.g. handing instruments to the dentist and using suction and other devices to keep the patient’s mouths dry)
- Wash and sterilize or dispose of dental instruments and equipment after use.
- Record patient dental history and create/update/maintain patient charts.
- Educate patients with regard to proper oral hygiene and preventative dental care.

As per the Texas State Board of Dental Examiners (SBDE), “You are permitted to make x-rays in Texas for one year from the first day of being hired as a dental assistant under the direct supervision of a dentist. During this first year of employment you will want to consider taking one of the Dental Board-approved courses listed below to continue making x-rays in your 2nd, 3rd and future years of service as a dental assistant.”

As per the U.S. Bureau of Labor Statistics, the rate of growth is expected to be 36 percent through 2018, a rate that is much faster than that for most other occupations. There are two primary factors for this rate of growth: 1) increase in population size with an accompanying increase in the demand for dental services so that dentists need to hire assistants to perform routine tasks; 2) greater emphasis on overall preventative health care, including dental care, by all age groups.
Education of Dental Assistants
According to the Commission on Dental Accreditation, there are no formal education requirements to become an entry-level dental assistant in any state and many dental assistants continue to be trained on-the-job. In these situations, the supervising dentist, dental hygienist, or senior dental assistant teach needed skills such as dental terminology, dental procedures, chairside assistance, recording patient histories, setting up patient charts, scheduling patient appointments and other office tasks. It may take a new dental assistant three to four months to become fully versed about job duties and able to work without constant supervision.
If you are a high school student with an interest in becoming a dental assistant, it is recommended that you take courses in biology, chemistry, mathematics, computers, and psychology.
For those wishing to pursue training in the field, The Commission on Dental Accreditation (CODA) of the American Dental Association accredits nearly 300 programs throughout the country. Most programs combine classroom study, laboratory work, and instruction in dental assisting practice and theory.
Coursework will include fundamentals of dentistry, dental pharmacology, dental office procedures, dental anatomy and physiology, clinical dental procedures, and dental equipment.
Programs within private vocational schools take about one year to complete and graduates will be awarded a certificate or diploma. Two year programs are offered in community and junior colleges and lead to an associate in science (A.S.) degree. Entry to either a certificate or associate’s program requires either a high school diploma or general equivalency diploma (GED).
Even those who have graduated from accredited training programs will participate in some type of formal on-the-job training or have previous experience. This training is necessary because dentists have varying work styles, office procedures, and methods of patient relations. Because of continuing advances in technology, dental assistants will also need to be kept current with regard to new equipment, instruments, and procedures.
Licensure and Certification
According to the Texas Board of Dental Examiners there are three levels of dental assistants:
“Qualified Dental Assistant” is a dental assistant who has received on-the-job training or instruction through a dental assisting school. There is no credential for this level of training or instruction.
“Registered Dental Assistant” is a dental assistant who has successfully completed the state-level registration process with the SBDE (State board of Dental Examiners). Dental Assistants who successful register and have been issued a Dental Assistant Registration Certificate by the SBDE may use the credential “Registered Dental Assistant” or “RDA”. Registration is required for those dental assistants who wish to take and develop X-rays.
“Certified Dental Assistant” is a dental assistant who meets the education and/or experience prerequisites established by the Dental Assistant National Board (DANB). Experiential requirements are typically 2 to 4 years experience as a dental assistant on either a full or part time basis. Candidates must also passes the DANB Certified Dental Assistant (CDA) Examination (including Radiation Health and Safety (RHS), Infection Control (ICE) and national-level General Chairside (GC) component(s), is currently CPR-certified and continues to maintain the CDA credential by meeting DANB requirements. Dental Assistants who complete this process may use the credential “Certified Dental Assistant” or “CDA.” The designation Certified Dental assistant is required for those who wish to perform radiologic procedures
Aside from higher salaries, certification will enable dental assistants to earn higher salaries and be eligible for such career advancement opportunities as a dental office manager, instructor in training programs, dental products sales representative, or claims processor/adjuster with health insurance carriers. Dental assistants may also return to school to become dental hygienists and be eligible for a much broader range of clinical patient care.
