“If we make our vision the conservation of tooth structure, but we never mention prevention or oral hygiene, we are hypocrites.” 

– Dr. Dan Fischer

Here at Ultradent, proper dental hygiene plays a key role in achieving our vision to improve oral health globally through minimally invasive dentistry. Without proper dental hygiene procedures and skilled hygienists to administer them, Ultradent’s vision and goal would, as Dr. Fischer says, not only be hypocritical…but in the end, futile.
So here’s to all of the dental hygienists out there who work hard every day to prevent tooth decay, teach and promote better oral health, and, when all else fails, help patients get back on track to good oral health through the many procedures and treatments they provide. Most importantly, thank you to all of the hygienists who carry their patients’ best interests at heart. We salute you and congratulate you on 104 wonderful years in the business!

Now…let’s take a look back over the last 104 years to see just how far dental hygiene has come.

The Beginnings of Dental Hygiene

With the world’s first formal dental school dating back to 1828, it seems ironic that it took almost 100 years for dental hygiene—the foundation of the maintenance of healthy teeth—to catch up.

It was a dentist by the name of Dr. Alfred Fones who is credited as the “Father of Dental Hygiene,” as he educated the first ever dental hygienist, his assistant Irene Newman. He trained her for one year in his practice before allowing her to take over the duties of scaling and polishing the patients’ teeth.

In 1913, Fones would establish the Fones School of Dental Hygiene at the University of Bridgeport in Bridgeport, Connecticut, which continues to educate dental hygienists today.

Since 1913, the profession has grown from one woman, Irene Newman, to more than 200,000 hygienists in the U.S. workforce today. In fact, last year, careercast.com named the job of a dental hygienist as the #14 best job in the country. This is thanks in large part to the positive hiring outlook, substantial salary, low stress, and family-friendly work environment. ​

Significant Milestones in Dental Hygiene

Through Fones’ championship of the dental hygiene profession, the state of Connecticut was the first state in the union to allow prophylaxis by a trained dental hygienist. But the practice caught on and spread throughout the country quickly.

By 1933, the American Dental Hygienists Association had been formed.

On January 25, 1945, Grand Rapids, Michigan became the first city to add fluoride to its water. The Read more about the discovery of naturally fluoridated water


In the 1950s, regular teeth cleanings became the standard for Americans, increasing dental office visits and further popularizing preventative care. Thanks to this, hygienists today can look forward to a great career. But let’s not overlook the benefits that they’ve brought over the years to the folks in the dental chair. Because of the popularization of dental hygiene, patients enjoy a wider breadth of preventative care than ever before. Before dental hygiene, one only visited the dentist after the onset of a toothache, which often served as a warning sign of more serious problems due to, well, poor dental hygiene.

In 1955, the first fluoridated toothpastes hit the market, helping to further prevent tooth decay throughout the country.

As the dental hygiene profession continued to grow and the equal rights movement spread, the word "female" was deleted from the ADHA Constitution and Bylaws in 1964. Subsequently, the first male dental hygienist, Jack Orio, RDH, graduated from the University of New Mexico in 1965.

In 1972, the first four dental hygienists were commissioned into the US Army, and by 1975, the U.S. Army expanded the addition of dental hygienists to its forces to provide services for enlisted soldiers and their families. During the 1970s, sealants also gained widespread popularity as a tool for caries prevention.

With the discovery of the AIDS virus in 1981, widespread panic spread throughout the country, as the cause and means of infection had not yet been identified. However, as researchers learned more, OSHA mandated changes in sterilization and personal protection equipment throughout dental and medical offices, requiring dentists and hygienists to wear gloves, eyewear, and masks while working on patients.

In the 1990s, the advent of tooth whitening and its popularization (in large part by Ultradent’s Opalescence Tooth Whitening Systems drove people to the dental office by the masses, where they were fitted for custom whitening trays and educated on the tooth whitening process by hygienists. Since then, the bright smile craze has never subsided, and new and inventive tooth whitening systems like Ultradent’s in-office whitening system, Opalescence® Boost™ whitening, and Opalescence’s disposable, take-home whitening system, Opalescence Go® whitening have made the process more easy and convenient than ever!

Hygienists today also play a key role in education and the promotion of better oral health—not only in dental offices, but in schools and even in remote parts of the world where they often donate their time as a humanitarian effort to teach children and adults how to prevent caries and decay.

Lastly, hygienists provide therapeutic services and treatments meant to stop disease and maintain or regain oral health. Some of these core procedures involve prophylaxis, scaling and root planing, the application of dental sealants and fluoride treatments, and in some cases, administering local anesthesia.

For all of the challenges dental hygienists have faced head on over the last 104 years, we thank you. It’s hard to imagine dentistry or healthy smiles without you!
