How to Become a Dental Hygienist

Step 1Earn a Degree

The first thing that you are going to want to do when you decide to become a Dental Hygienist is to figure out which type of degree you want to earn.

It’s possible to work as a Dental Hygienist with an Associates’ degree, but it’s also possible to earn a Bachelors’s degree in Dental Hygiene.

Many community colleges, universities, dental schools, and technical schools provide Dental Hygiene programs, you’ll have to look around to see what works best for you.

In order to be accepted into a program, you’ll need to have a high school diploma or GED and have knowledge of these subjects:

  • Health
  • Biology
  • Psychology
  • Chemistry
  • Math
  • Speech

While in school, it is also required that you work with patients which can help with real-life work experience.

Since most dentists require only an Associates’ degree in order to be hired as a Dental Hygienist, that is what we will talk about today.

Some of the classes that you can expect to take to earn an Associates degree include:

  • Physiology
  • Nutrition
  • Radiography
  • Pathology
  • Medical Ethics
  • Patient Management
  • Periodontics

A typical Dental Hygienist program can take anywhere from two years to three years to complete.

You’ll want to make sure that the school you attend is accredited with the Commission on Dental Accreditation.

Step 2Become Licensed

Every state in the United States requires that a Dental Hygienist be licensed in order to work.

In order to be a candidate for licensure, you’ll need a passing grade on the National Board Dental Hygiene Examination.

You’ll also need to take the state-authorized licensure exam, which can vary depending on where you live.

With both exams, you’ll be required to showcase your skills in clinical dental hygiene both physically and in written form.

When it comes to the National Board Dental Hygiene Examination, there are some specific areas to keep in mind when studying:

  • Scientific Basis for Dental Hygiene Practice
  • Provision of Clinical Dental Hygiene Services
  • Community Health/Research Principles

There are two parts to this test, and each part costs $100 to take.

You will have thirty days from the day that you pay for the test to take it.

It is possible to take the test up to three times in one year.

Another thing to keep in mind is that licensure doesn’t last forever, you’ll need to renew your license after two years of working as a Dental Hygienist.

Step 3Find a Job

After you become licensed, it’s time to get in some work experience.

You may already have some work experience through clinicals, internships, and other opportunities while going through a Dental Hygienist program, which can look great on your resume.

  • Dental Radiography
  • Public Health Administration
  • Dental Hygiene Educator
  • Pediatric Dental Hygienist

If you’re looking for something more long term or something with more upward mobility, it may be necessary to seek higher education.
