Introduction




Are you interested in the field of dentistry? This broad field in the health care sector offers you many career options. Completing the activities in this tool kit will give you the opportunity to try out some of the tasks you would accomplish as a dentist, dental hygienist, dental technician, denturist or dental assistant.
Dentists
Dentists are tooth specialists. General dentists perform regular checkups, diagnose and treat teeth and gum problems, and maintain and improve the appearance of their patients’ teeth.1 Dentists can also specialize: there are nine recognized dental specialities in Canada, including dental public health, oral medicine and pathology, orthodontics and dentofacial orthopedics, pediatric dentistry, and periodontics.2
Dental Hygienists
Dental hygienists are specialized health care professionals who check and clean patients’ teeth, take x-rays and discuss proper oral hygiene with patients. They also report any problems to the dentist and maintain dental records.3
Dental Technicians
Also called dental lab techs or dental technologists, dental technicians build and repair dental restorations and prosthetic devices such as crowns, inlays and bridges. They make plaster or resin models of patients’ mouths and build wax models of teeth that need to be replaced. Using these models, they can then create exact replicas of lost teeth in porcelain.4
Denturists
Denturists are “specialized dental care professionals who design, construct, fit and repair removable dentures.”5 Unlike other dental professionals, they usually work both directly with patients and in a laboratory setting. They will examine patients to determine what type of dentures are needed and then construct the appropriate dentures using wax, metal and plastic. They may also make and fit other oral devices such as mouth guards and teeth-whitening trays.6
Dental Assistants
Dental assistants work closely with dentists. They clean and sterilize equipment, set up trays for procedures and help patients feel as comfortable as possible. They also assist dentists during procedures, passing instruments and equipment as required. Dental assistants may also take x-rays, provide patients with information about oral hygiene, book appointments and do filing.7
Do any of these career options appeal to you? Enjoy your exploration of the world of dentistry!


Activity



1


P laster dental models
During this activity, you will discover what adult dentition looks like and will have the opportunity to test your motor skills by working on a task that is typically performed in dental medicine. This work requires rigour and precision.
Your task is to make two dental models out of plaster using rubber moulds.8 You will notice that certain teeth are missing (see Figure 1.1); you will carve these out of wax in Activity 2.
