Oral care is as essential to most Americans as medical care. However, services are often scarce because there are too few oral care professionals to meet the growing demand. If you’re passionate about smiles, why not become part of this growing industry as a dental assistant? Few careers are as personally and professionally rewarding, and Florida National University offers a Dental Assistant program. So, what does a dental assistant do?
What Does a Dental Assistant Do?
Dental assistants work with licensed oral care professionals, managing clinical and administrative duties, from scheduling to chairside assisting. You’ll be part of a supportive team dedicated to dental health.
The work includes:
Dental assistants handle administrative tasks, such as scheduling appointments, processing insurance claims, managing referrals, and ordering supplies — anything that helps the practice run smoothly. Team players contribute to a well-organized and productive work environment.
Patients may have preexisting medical conditions that require special precautions before procedures. For example, people with a recent joint replacement should take prophylactic antibiotics before most treatments. Dental assistants screen patients for health concerns by exploring their medical history, reviewing allergies, and obtaining vital signs. Safety is always the top priority.
Preparing Treatment Rooms
Preparing treatment rooms in advance improves efficiency while minimizing wait times. Dental assistants set up the necessary equipment, ensuring that the right instruments, materials, and supplies are readily available for the dentist.
Dental assistants with expanded function training can take X-rays in most states. You’ll prepare the patient, position the X-ray machine, and snap images for the dentist to review. Minimizing radiation exposure is an integral part of the job. You’ll use leaded devices such as aprons, gloves, and thyroid collars to protect yourself and patients from larger-than-necessary doses. Exposure is cumulative.
Dental assistants participate in four-handed dentistry, where the dentist and assistant work together to manage treatments. You’ll pass instruments, manage water and suction, prepare treatment materials, and more, allowing the dentist to focus on patients with fewer interruptions.
Dental assistants perform low-risk treatments under the supervision of a licensed professional. Examples include coronal polishing, applying sealants, and making mouth or tooth impressions.
Oral care environments can harbor dangerous pathogens. Dental assistants implement infection control measures to keep patients safe from unseen microbes. This process includes sanitizing treatment rooms between visits and sterilizing instruments to ensure a hygienic environment.
Some dental assistants help in the lab with simple tasks such as denture alignments, polishing restorations, and creating custom whitening trays. In an orthodontic practice, they may also clean and adjust oral appliances.
Continuity of care requires precise and accurate documentation. During procedures, dental assistants chart treatment details, including the teeth involved, the materials used, and the proposed timeline for follow-up treatments.
Dental assistants are an essential source of information for patients, educating them on timely topics, from oral hygiene and preventive care to restorative procedures and post-operative self-care whether counseling patients with toothaches or helping kids learn to floss, sharing your knowledge about oral health will be among your most impactful responsibilities.
Where Do Dental Assistants Work?
Most dental assistants work in private dental practices. As the industry grows, however, they’re popping up in unconventional places. Opportunities are expanding in specialty clinics, hospitals, and even schools.
How Do You Become a Dental Assistant?
Training requirements vary by state. And they change often, so it’s essential to check with state regulators for details.
But in general, becoming a dental assistant is as easy as completing a vocational school program. All you need to apply is the willingness to learn and a high school diploma or equivalency certificate.
What Do You Learn in a Dental Assisting Program?
Dental assisting programs are job-focused, meaning they cover the skills you’ll need to succeed in any setting through a blend of classroom theory and practical, hands-on experience.
Introduction to Dental Assisting
This introductory course provides a general overview of the oral care profession and the role of dental assistants.

- Tooth surfaces, such as occlusal, buccal, mesial, and distal, and where to find them
- Tooth morphology — internal and external tooth anatomy, including the crown, root, pulp, and dentin
- Oral cavity structures — a look at the periodontium, the supporting structures of the teeth, including the gingiva, periodontal ligament, cementum, and alveolar bone
- Occlusion — how the upper and lower teeth come together
- Variations in tooth anatomy — normal and abnormal variations in tooth structure plus age-related wear patterns
Handling restoration materials is a critical component of a dental assistant’s job. This course covers the various compounds used in dentistry, including their properties and applications.
- Material classifications — the grouping of materials by function as therapeutic, preventive, prosthetic, and auxiliary materials
- Material properties — the physical and chemical characteristics of dental materials, such as hardness, elasticity, and thermal conductivity
- Impression materials
- Restorative materials, including amalgam, ceramic, and resin
- Color-matching — shade selection for a natural look
- Cement and adhesives — materials used for bonding restorative materials to tooth structures
- Material handling and safety — hazards and precautions associated with specific materials
Diet, Nutrition, and Oral Hygiene
Dietary choices influence oral health. As educators, dental assistants must understand how nutrition impacts preventive care.
This course covers:
- Oral anatomy and physiology — how the structure and function of the oral cavity contribute to human nutritional
- Effects of diet on oral health — the types of foods and beverages that harm or protect teeth
- Dietary nutrients — the role of critical nutrients, such as calcium and vitamins D and C, in a tooth-friendly diet
- Eating disorders — the oral complications of eating disorders, such as anorexia and bulimia, and how to support patients with these conditions
