Work environment

Workers in this occupational group typically work 32–40 hours per week. Those in private practices may work on a part-time schedule or work evenings and weekends.

Most work in clean, well-lit offices. Workers in rural and remote communities may have to travel great distances by vehicle or small plane to reach patients. They may also have to carry heavy equipment and materials for treatment. In the absence of repair services, they may troubleshoot and repair dental equipment.

Workers in these occupations must use sterile techniques and follow proper radiological procedures when taking X-rays. These workers wear safety glasses, masks, gloves and scrubs or lab coats to protect themselves from infectious diseases.

Insights from industry

A growing and aging population will require more dental services, which will result in new job openings for these workers. Job opportunities will also become available due to retirements.

As with many health-care professions, there is a shortage of dental hygienists in rural communities of the province. Increased job opportunities may be available in these areas.

Dental hygienists carry a much broader scope of responsibilities than in the past. They are dental health-care educators who instruct patients in oral hygiene procedures and promote community dental health programs. The role of dental hygienists in areas outside clinical practices, such as community health centres and residential care facilities is expected to increase.

Advances in biomedical sciences and disease patterns continuously change the delivery of dental care. Improvements in many aspects of dental care make it possible for dentists to carry out more complex treatments, which may increase overall demand for dental services.
