Studies & Degrees in Dental Assistant

Dental assisting is the training of the people who work at the dentist's side. They prepare the treatment room, look after the patient before and after treatment and keep the practice running. The US Bureau of Labor Statistics (BLS) sums up the job in one line: dental assistants provide patient care, take x-rays, keep records and schedule appointments.

The name of the job changes with the country. It is dental assistant in the United States and Canada and dental nurse in the United Kingdom. In Spain the same tasks are part of the official vocational qualification in auxiliary nursing care. Courses mix classroom teaching, laboratory work and supervised practice in a clinic. Students usually learn:

  • the anatomy of the teeth, gums, jaws, head and neck
  • infection control and the sterilisation of instruments
  • chairside assisting: preparing materials, handing instruments, using suction
  • dental radiography and impressions of the teeth
  • patient records, appointments and oral hygiene advice

Qualifications and levels

Dental assisting is taught below degree level in most countries, and the rules differ a great deal from one place to the next.

  • United States. According to the BLS, many programmes take about one year and lead to a certificate or diploma; two-year programmes that lead to an associate's degree are less common. Most are offered by community colleges. Some states require assistants to graduate from an accredited programme and pass an exam; in others there are no formal educational requirements and assistants learn on the job. Century College in Minnesota, for example, offers a diploma and an Associate of Applied Science degree.
  • US certification. The Dental Assisting National Board (DANB) runs the Certified Dental Assistant (CDA) exam: 245 questions in 195 minutes. Candidates qualify by graduating from a CODA-accredited dental assisting programme, or with a high school diploma and at least 3,500 hours of approved work experience.
  • Canada. The Certified Dental Assistant certificate at Camosun College in Victoria lasts 10 months, full time, and includes six weeks of practicum in a dental office. Graduates must pass the National Dental Assisting Examination Board (NDAEB) examination to register and be licensed in British Columbia.
  • United Kingdom. NHS Health Careers explains that people can usually start as a trainee dental nurse without academic qualifications, but must complete a course approved by the General Dental Council to qualify. Training is usually an 18-month level 3 apprenticeship.
  • Spain. The official route that covers dental assistance is a nursing one. The intermediate vocational training (FP) qualification Técnico en Cuidados Auxiliares de Enfermería lasts 1,400 hours and includes a module on dental and stomatological assistance techniques. The higher-level cycle Técnico Superior en Higiene Bucodental (2,000 hours) trains dental hygienists, a different job with more clinical responsibility.

Private training centres also offer short dental assistant courses. Before enrolling, ask the school what recognition its certificate has where you plan to work.

Where to study it

SpainExchange lists 20 active schools for dental assisting. Thirteen are in the United States, three in Spain, and one each in Canada, Ukraine, the United Kingdom and Argentina. The US schools are mostly community and technical colleges, such as Alamance Community College in North Carolina, which teaches a Dental Assisting diploma with day and evening options, and Hudson Valley Community College in New York, whose one-year online certificate combines 27 credit hours of coursework with 225 hours of clinical experience. In Spain the list includes CCC Centro de Estudios in Madrid, which teaches the official Higiene Bucodental cycle over two years, Churruca Formación in San Sebastián and Imásd Forma in Vigo. Fundación CIEP is in Villa María, Argentina.

Teaching is in English in the United States, Canada and the United Kingdom, and in Spanish in Spain and Argentina. International students should check two things early. The first is whether the programme accepts them: Camosun College lists its certificate as open to international students, with estimated tuition of $22,587 for the whole programme between 1 September 2026 and 31 August 2027. The second is whether they can be licensed afterwards. Hudson Valley Community College warns that a New York licence as a Registered Dental Assistant is only open to US citizens and permanent residents.

Careers

Almost all dental assistants work in dental practices. In the United States they held about 388,600 jobs in 2025, 91% of them in dentists' offices, according to the BLS. It projects employment to grow 7 percent from 2025 to 2035, with about 53,000 openings a year.

Century College also names public health institutions, dental school clinics, military dental services, and dental supply and insurance companies as employers. With extra training, dental nurses in the United Kingdom can take x-rays and impressions or give oral health education.
