Dental assistants wear gloves, masks, eye wear and protective clothing to protect themselves and their patients from infectious diseases. Safety procedures are also followed when using X-ray machines to reduce associated risks.

Insights from industry

Job opportunities will come from new job creation and the need to replace retiring workers.

Overall, job opportunities for dental assistants should remain strong as B.C.'s growing population continues to increase the demand for dental services. The growth in awareness about good dental hygiene has increased the level of dental care in the general population. As people keep their natural teeth longer, older people will require more dental care than previously required. Cosmetic dental procedures, such as laser whitening and caps are also gaining popularity.

Since Level II (certified) dental assistants may perform a wider range of duties than Level I dental assistants, they are generally in higher demand.
