What Is Dental Hygienist?

A dental hygienist is a licensed dental or oral health professional who specializes in the prevention and treatment of oral diseases. A dental hygienist focuses on the prevention and treatment of oral conditions. They work to protect both teeth and gums and to protect the overall health of patients.

They have dental hygienist recognition by obtaining a license after passing a written national board exam. They specialize in treating patients directly. Dental hygienists can also work as academics, administrators, and researchers.

Dental hygienists play a role in maintaining good oral health in patients. They help patients improve their mental and physical health. They can explain to a patient the relationship between diet and oral health.

A dental hygienist also tells patients how to choose a toothbrush and shows them how to brush and floss teeth.

Dental hygienists use a variety of tools. They use their hands most of the time to take care of the patient but sometimes they use heavy tools. 

The scope of work of a dental hygienist is very wide. If he wants, he can work with dentists, dental therapists, oral health therapists as well as other dental professionals.

History Of Dental Hygiene

Dental disease prevention methods became popular among dentists and dental hygienists in the late 1800s. At that time, dentists were trained to treat routine prophylaxis in the fight against dental disease. 

During that time, Philadelphia D.D. Smith described the prophylactic methods to his colleagues and patience which became acceptable and increasingly popular to everyone.

Dental hygiene began more than a hundred years ago and has continued to change and explore as time goes. Dr. Alfred Fones was the first person to open a school for dental hygienists in 1913. He was the first person to realize the importance of oral care to reduce the bacteria that caused disease.

 The School of Dental Hygiene, founded by Dr. Fonsi, still exists, known as the University of the Brigade.  

The first person to be trained as a dental hygienist was Irene Newman. He also became the first licensed dental hygenist.

In 1914, members of the first Dental Hygiene graduate class were assigned to a school-based work to highlight the importance of oral care for children.

American Dental Hygienists Association known as ADHA was first established in 1923. After that, the growth of the dental hygienist profession increases significantly. As a result, all the states had licensed dental hygienists by 1952.

As dental hygienist programs spread all over the world, ADHA implemented certain conditions for admission to the program. They first made a high school diploma compulsory for the license.

Until 1940, a  course was required to be licensed as a Dental Hygienist. The duration of that course was two years. ADHA then adopted the label “Registered Dental Hygienist” in 1940.

1970 was the turning point in the hygiene industry when ADHA established guidelines for continuing education in dental hygiene. The 1990s were conducive to dental hygiene when dental hygienists registered in fourteen states were allowed to perform local anesthesia.

By 2000, local anesthesia administrations were approved by a registered dental hygienist in more than half of the fifty states.

The number of dental patients has increased year by year. In the 1950s, less than one-third of the population visited dental clinics. This number has increased by 67% since 2000.

Dental Hygiene Program

Most institutions or health schools do not require a bachelor’s degree to accomplish a dental hygienist program. First, you have to complete the prerequisites, which usually take you about a year. Once all the prerequisites are done then you can apply for a hygiene degree. 

There are hundreds of dental hygiene programs currently approved in the United States. Most dental hygiene programs or courses are two years long.

And in addition to studying dental hygiene, you will earn an associate’s degree in applied science in dental hygiene. An associate’s degree in dental hygiene will teach you how to provide a patient with precautionary hygiene care for teeth and gums, as well as treatment solutions for various oral diseases. 

There is also a 4-year program where you get a bachelor’s degree in dental hygiene. These programs focus on the deeper subjects than the two-year program. It is developed for dental hygienists who want to study with special care.

Some four-year program topics may contain dental health theory, examination, research, or dental conditions. So It is up to you to decide which degree you want to take.

Dental Hygiene License

After getting a degree in Dental Hygiene, you must get a license as a Dental Hygienist. To get a license, you need to pass an examination called the National Board of Dental Hygiene Exam. If you do not get the pass mark, you will have to take the exam again.

After earning a degree and licensing it, you will be able to work as a qualified dental hygienist. But no matter how educated you are, you need to keep your learning experience going. Because even after you get your degree and license, you must renew that license every 2-3 years. So you must continue studying this subject.

Role Of A Dental Hygienist

A dental hygienist plays a variety of roles. Just like a dentist, a dental hygienist provides preventive treatment which is important for maintaining oral health. A dental hygienist always greets his patient with a smile and he does his utmost care for his patient.

Dental hygienists do much more than preventive dental treatment. They are trained to answer all questions of their patients and to make actionable recommendations for the improvement of the patient’s oral health.
