The Most Important Thing Your Dental Hygienist Does Isn’t Clean Your Teeth

October is National Dental Hygiene Month, which means you’ll probably see plenty of posts celebrating dental hygienists. Cute memes. Tooth-shaped cookies. Maybe a new tumbler if you’re lucky. And I am all for celebrating dental hygienists. We work hard, our backs hurt, and we certainly never turn down snacks in the break room.

But maybe the best way to celebrate our profession is to finally recognize what dental hygienists actually do. Because if you still think we “clean teeth,” you’re missing a whole lot of what happens in that operatory. Yes, we remove calculus and biofilm. We polish teeth. We probably remind you to floss (although hopefully we’ve gotten a little more creative than that by now). But that’s just one piece of a much bigger picture.

We are highly educated health-care professionals

Dental hygienists don’t learn to “clean teeth” in a few weeks of training. Before ever picking up a scaler, we’ve studied anatomy, physiology, microbiology, chemistry, nutrition, psychology, pharmacology, pathology, and a whole bunch of other classes that probably kept us up way too late studying.

Then comes the clinical education, written and clinical board examinations, licensure, and continuing education throughout our careers. Depending on the hygienist sitting beside you, there may be an associate’s, bachelor’s, master’s, or even doctoral degree behind those initials RDH. All that education walks into the operatory with us every single day.

We are assessors

Before we ever touch a tooth, we’re gathering information. We’re reviewing medications and medical history. Taking blood pressure. Looking at radiographs. Examining tissues. Measuring periodontal pockets. Assessing bleeding. Looking for recession, inflammation, decay, wear, changes in saliva, suspicious lesions, and subtle changes from the last time we saw you.

And we’re asking questions. Lots of questions. How are you sleeping? Any new medications? Dry mouth? Reflux? Have you been diagnosed with diabetes? Are you pregnant? Going through menopause? Preparing for a joint replacement or another surgery? Has anything changed since we saw you last?

We’re not being nosy. Okay, maybe we’re a little nosy. But mostly we’re connecting dots.

We are disease detectives

The mouth gives us clues. Sometimes those clues point toward periodontal disease or tooth decay. Other times they tell us that we need to keep asking questions.

Years ago, I worked in a practice that purchased the patient records of a retiring dentist. I was tasked with seeing many of those patients as they transitioned into our practice. The dentist and hygienist they had been seeing were lovely people, and their patients adored them. But as I began assessing these new patients, I found a lot of disease. Cavities. Ledges of calculus below the gumline. Periodontal disease that had gone undiagnosed and untreated.

It was a delicate situation. These patients trusted the people who had cared for them for years, and my job wasn’t to criticize their previous care. It was to meet them where they were and figure out how to move them toward health.

There was one patient I will never forget. Over a series of appointments, we worked together to improve her periodontal health, but her tissues weren’t responding the way I expected them to. Something wasn’t adding up. So I kept asking questions, and eventually I encouraged her to schedule a physical with her physician.

She did. She had cancer. I didn’t diagnose her cancer. That’s an important distinction. What I did was recognize that what I was seeing didn’t fit the pattern I expected. My education and clinical experience told me to stay curious rather than simply keep “cleaning her teeth.”

That’s dental hygiene.

We’re trained to notice, assess, compare, and question. To recognize when something isn’t responding the way it should and sometimes say, “I think we need to look a little deeper.” We don’t just ask, “What do I see?” We ask, “Why am I seeing it?”

We are prevention specialists

Dentistry has traditionally been pretty good at fixing things after they break. Dental hygienists have this amazing opportunity to work further upstream. What if we can identify the risk before the cavity? The inflammation before the bone loss? The home-care challenge before disease progresses? The dry mouth before rampant decay?

I use the word preoptimization a lot when I speak. To me, it means helping our patients get as healthy as possible so their oral health isn’t draining their overall health. Because the mouth is not some separate little island floating outside the rest of the body. What happens there matters.

And we don’t have to wait until disease gets worse before we do something about it. We can intervene. We can educate. We can change the environment. We can help our patients understand what is happening in their own mouths and give them the tools to change the trajectory.

That’s a pretty powerful place to be.

We are educators—but hopefully not lecturers

For years, dental hygienists had a reputation for telling people to “brush and floss better.”

How’s that working for us?

Education isn’t dumping everything we learned in hygiene school onto a patient and hoping something sticks. And it certainly isn’t floss shaming someone as we hand them a goody bag and send them out the door.

It’s figuring out what matters to the person sitting in our chair. It’s showing them what we’re seeing and asking what they’re seeing. It’s listening. It’s asking better questions. It’s co-discovering disease instead of announcing it.

When patients understand their own health and have a voice in what happens next, the conversation changes.

We are part of the health-care team

This might be the piece I want us to shout the loudest.

Oral health is health.

We’re caring for human beings, not just teeth. We’re watching inflammation. We’re talking about nutrition, tobacco and nicotine use, medications, sleep, blood pressure, diabetes, pregnancy, menopause, cancer risk and dozens of other things that don’t fit neatly into the category of “teeth.”

And dental hygienists are doing this work in more places than ever. We’re in private practices, public health, education, research, mobile dentistry, corporate roles, sales, consulting, advocacy and places our profession probably couldn’t have imagined when it began.

Our profession is so much bigger than a prophy.

Stop calling it “just a cleaning”

I get it. “I’m going to get my teeth cleaned” is easy to say. But words matter.

When an appointment filled with assessment, prevention, education, disease detection, instrumentation, collaboration, and individualized health care gets reduced to “a cleaning,” it’s not surprising that patients—and sometimes even our own dental teams—underestimate the value of dental hygiene.

So this Dental Hygiene Month, absolutely celebrate your hygienists. Buy the lunch. Bring on the cupcakes. Give us the cute tooth socks. We will happily take all of it.

But also recognize our education. Listen to our recommendations. Give us the time, technology, instruments, and support we need to provide comprehensive care. And recognize that the person sitting beside the patient with a mirror and an explorer may see something everyone else has missed.

And to my fellow hygienists, don’t forget the value you bring to that chair either. Stay curious. Ask the extra question. Look a little closer. Speak up when something doesn’t make sense. Use that education you worked so hard for.

Yes, we clean teeth.

But it might just be the least important thing we do.
