Trying to decide if you should pursue a career as a dental assistant or a dental hygienist? Both dental assistant and dental hygienists are members of the support team within a dental office. Although their jobs may seem interchangeable to those outside the industry, the responsibilities of each role and the training required are different.
- Dental hygiene involves a greater degree of patient education and preventative dental care than does the work of dental assistants who largely provide support and general office management.
- While dental assistants may complete a training program lasting about one year to become registered, there is no requirement in California to do so and you can begin a career in this field right after high school. Indeed, many dental assistants are trained on-the-job. In contrast, dental hygienists need a minimum of an associate’s degree to work in a private dental office and must become registered by passing written and clinical examinations.
- The entry-level salaries of dental hygienists are nearly double that of dental assistants due to their advanced education and skill set.
Below we will provide an overview of each career so that you may plan accordingly.
