Do Your Strengths Align with a Dental Hygiene Career?

The dental hygiene field is rewarding for many, but it’s not a great fit for everyone. Before applying to a school for training, evaluate whether this career is a good choice for you. The following are some of the most important questions you can ask yourself.

If you are meticulous about details, then dental hygiene could be an excellent fit. While cleaning teeth is not all dental hygienists do, it is important that a dental hygienist takes care of the little things when cleaning teeth and in overall care of patients.

Dental hygienists work in a variety of settings, such as pediatric or hospital-based, alongside dentists and assistants, to reach the goal of complete patient care. As a health care provider, dental hygienist should enjoy helping patients and providing exceptional overall care to every patient in their chair daily.

Everyone goes to the dentist. Patients may not understand the treatment they are about to receive, so dental hygienists need to have strong communication skills to explain procedures to them. Also, they may be required to give patients information on how they can practice good dental hygiene at home.

Patience and empathy are crucial in this field because professionals often work with people — such as children — who may be afraid of the treatment they’re about to receive. People in this field need to be able to calm patients’ nerves and put their mind at ease.

Since the inside of people’s mouths doesn’t leave a lot of room to work in, dental hygienists must have the dexterity and hand-eye coordination needed to work on specific teeth. Without these skills, they may not be able to navigate the tools they use into the correct positions.

If you answered “yes” to these questions, you may be a great fit for dental hygiene. Now that you know this is a good career, continue reading to find out what you need to do next to get started.

Research Dental Hygiene Programs

People seeking foundational knowledge to start up their careers can pursue an associate degree, which provides a comprehensive understanding of the essential principles required for their profession. For those aiming to secure higher-level positions, a bachelor’s degree offers more extensive training and expertise.

Some schools provide dental hygiene master’s degrees, catering to experienced professionals aspiring to transition into administrative roles, educate future dental hygienists, or engage in industry research. This advanced degree equips them with the necessary skills and insights to excel in the top tier of the dental hygiene profession.

Choose Your Education Path

Once you’ve decided where you want to go in your career (or if you have a good idea), choose the starting point that makes the most sense. Here’s some key information that can help you chart your own path to becoming a dental hygienist.

Volunteer at a dental office

Volunteering in a dental office or shadowing a dental hygienist can be a great way to experience the day-to-day life of the job before diving in. Get a good idea of the tools they use, how they interact with patients and co-workers, and the overall feel of the work environment. And don’t forget to ask questions. Ask about the benefits of the job, the challenges of the profession, and how the dental hygienist views career advancement.

An associate degree

Earning an associate degree is the most common path for training to become a dental hygienist. These programs, which take two to three years to complete, are for students who want to get the theoretical knowledge and hands-on training to prepare for an entry-level job and earn the certification needed for employment. In addition to dental hygiene coursework, students in these programs also complete liberal arts classes, such as math, English, and psychology, to give them a broad education and additional skills they can use in the workplace. As a result, students leave the program with important abilities, like critical thinking and problem-solving skills, they can apply to patient care.

A bachelor’s degree

Although associate degrees are the more common training that dental hygienists receive, those who want to earn a four-year bachelor’s degree can stand out from the competition when looking for a job. These programs are designed for students who want to have more options than just clinical practice, such as teaching or research, or to advance their education above an associate degree. In addition to completing dental hygiene training classes that provide a theoretical foundation and clinical training, these programs also require classes such as anatomy and physiology, microbiology, nutrition, and the humanities and social sciences.

Consider a master’s degree

Dental hygiene master’s degrees are for professionals who want advanced training to become leaders in the field. Whether their goals are to become educators, researchers, public health professionals, or managers in oral health clinical settings, these programs build on students’ current knowledge and skills and teach them the leadership principles needed for higher-level jobs.
