Let Purple Reign: Unleashing the Full Potential Of Dental Hygiene

At RDH Under One Roof, Katrina Sanders, RDH, delivered a powerful closing mega session that did far more than end the conference—it opened a door. With energy, courage, and unmistakable passion for our profession, she challenged dental hygienists to imagine a future in which we are no longer defined solely by “cleaning teeth,” but recognized for the full depth of our education, clinical judgment, preventive expertise, and ability to change lives. Katrina gave voice to a conversation our profession urgently needs, and she did it in a way that was bold, inspiring, and deeply affirming. Her message stayed with me long after the session ended and became the spark for this article. Thank you, Katrina, for using your platform to challenge us, champion us, and remind us that dental hygiene is capable of so much more.

This article is my attempt to continue that conversation—to move from inspiration into possibility and explore what practicing to the full potential of dental hygiene could actually look like.

Purple has long represented the dental hygiene profession. It symbolizes our identity, our history, our education, and the professional community we share. Perhaps it is time for purple to represent something even greater: a profession ready to rise. It is time for dental hygienists to step fully into our education, our licensure, our clinical judgment, and our potential—and to show the world just how much more dental hygiene can be.

It is time to Let Purple Reign.

Dental Hygiene Is at a Crossroads

The traditional dental hygiene appointment often follows a familiar sequence. We review the medical history, take radiographs, complete periodontal measurements, remove deposits, polish the teeth, apply preventive products, and provide home-care instructions. These services matter. Thorough periodontal instrumentation, biofilm removal, risk assessment, and patient education remain essential, but they should not represent the outer limits of our profession. Dental hygiene was never meant to be reduced to “cleaning teeth.” As technology advances and traditional procedures become increasingly delegated, automated, or redefined, we must decide what comes next. Do we protect our identity by holding more tightly to the tasks we have always performed, or do we demonstrate that our greatest value has never been found solely in our instruments?

Our greatest value is found in what we notice. It is in the questions we ask, the patterns we recognize, the risks we identify, and the diseases we help prevent. Why is this patient bleeding despite excellent home care? Why did caries activity suddenly increase? Why has the mouth become dry? Why is periodontal breakdown continuing after technically adequate treatment? Why is the patient exhausted, clenching, mouth breathing, or waking throughout the night? Why is a lesion not healing?

These questions are not distractions from dental hygiene. They are at the heart of it. When we stop asking why, we become technicians completing procedures. When we investigate the why, we become prevention specialists, periodontal therapists, clinical investigators, educators, coaches, and essential members of the healthcare team.

The Dental Hygienist as a Prevention Specialist

Prevention should be more than telling patients to brush, floss, and reduce sugar. True prevention requires investigation. Periodontal disease and dental caries are rarely explained by one organism, one behavior, or one missed brushing session. They develop through an interaction among biofilm, host response, saliva, inflammation, nutrition, breathing, medications, hormones, lifestyle, and systemic health. It would certainly make our job easier if there were always one clear cause to identify and correct—but oral disease is rarely that simple. More often, it is the combination of several, and sometimes many, of these factors that shifts the oral environment toward disease. True prevention means looking deeper, asking better questions, and identifying the underlying contributors that are keeping the patient from returning to health.

A comprehensive preventive appointment may assess salivary flow, pH, buffering capacity, dry-mouth symptoms, medication burden, biofilm maturity, inflammation, diet, acidic exposure, airway, sleep, breathing, oral posture, reflux, hormonal transitions, blood sugar regulation, nutrient status, stress, fatigue, and healing capacity. It should also consider whether the patient has the knowledge, tools,
dexterity, motivation, and emotional readiness to follow the plan.

Prevention is not one product or one procedure. It is the process of discovering what is placing a patient at risk and creating a plan that is personalized, realistic, measurable, and responsive to change.

Being BioLogical: Understanding the Terrain and the Trigger

Practicing biologically means looking beyond visible signs and asking what allowed disease to develop, persist, or return. Plaque, calculus, acids, traumatic forces, and pathogenic organisms matter because they may act as triggers. Yet the trigger alone does not explain why one patient experiences rapid destruction while another remains stable, or why one patient develops rampant caries while another with similar habits does not.

We must also evaluate the host terrain. The terrain includes the patient’s immune response, inflammatory burden, saliva, nutrition, hormones, metabolic health, airway, sleep, breathing, medications, stress physiology, nervous system regulation, and ability to repair. These factors influence whether the patient remains resilient, develops disease, or responds successfully to treatment. A bioLogical hygienist asks three essential questions: What is triggering the disease? What within the host terrain is allowing it to continue? What does this patient need to heal?

If we address only the trigger, we may temporarily reduce bacteria, biofilm, inflammation, or acid exposure without changing the conditions that allowed disease to develop. If we support the terrain while leaving an aggressive trigger undisturbed, healing may also remain incomplete. The goal is to understand how the two interact and to address both.

Healing requires more than completing a procedure. It requires creating an oral and systemic environment in which the patient can respond. Without understanding both terrain and trigger, we may manage symptoms without truly helping the patient move forward on a healing journey.

More Thorough Periodontal Therapy

Full-potential dental hygiene must include a deeper approach to periodontal care. Periodontal therapy cannot be reduced to removing calculus from root surfaces. Calculus is important, but it is only one part of a larger biological process. We must evaluate disease activity, biofilm behavior, bleeding, suppuration, tissue breakdown, homecare effectiveness, and the patient’s response to previous treatment. We also need to consider the factors that influence inflammation and repair, including immune function, blood sugar regulation, hormones, smoking, nutrition, sleep, airway, medications, stress, and systemic inflammatory burden. When tissues continue to bleed, pockets fail to improve, or disease progresses despite adequate instrumentation, we must look beyond the root surface and ask what may be interfering with resolution.

More comprehensive care may include meticulous instrumentation, ultrasonic technology, guided biofilm therapy, phase-contrast microscopy, salivary or microbial testing, inflammatory markers, oxygen-ozone applications, tray therapy, personalized home care, and carefully timed reevaluation.

The tools are not the goal. Their purpose is to help us see disease activity more clearly, personalize treatment, and measure whether the patient is improving. Periodontal care should not end when instrumentation is complete. It should include documentation of tissue response, refinement of the home-care plan, investigation of unresolved inflammation, and collaboration or referral when
appropriate.

The question is not simply, “Did we clean the pocket?” The more important question is, “Did we change the disease process, and is the patient healing?”

More Comprehensive Caries Prevention

Dental caries deserves the same depth of investigation. Finding a cavity is not prevention, and recommending a product after a lesion has developed is not a complete caries strategy. We need to understand why the oral environment is no longer protecting, repairing, and remineralizing the teeth.

A thorough assessment may include salivary quantity and quality, resting and stimulated pH, buffering capacity, biofilm activity, eating and sipping frequency, acidic exposure, medication-induced dry mouth, mouth breathing, reflux, airway, sleep, hormonal changes, mineral availability, home-care practices, and opportunities for remineralization. It is critical we look at the entire host picture or we will never conquer dental caries.

A bioLogical caries protocol examines both trigger and terrain. Sugars, repeated acid challenges, cariogenic biofilm, reflux, and ineffective plaque control can drive demineralization. Saliva, buffering, breathing patterns, medications, hormones, nutrition, metabolic health, and sleep influence whether the teeth remain resilient or become vulnerable. The dental hygienist is ideally positioned to lead this investigation. We see patterns over time and can connect a new medication, hormonal transition, dry-mouth complaint, sleep concern, or reflux pattern with a change in caries activity. The goal is not simply to apply a product. It is to rebuild an oral environment capable of protection and repair.

The Dental Hygienist as a Biofilm Scientist

Biofilm is not merely plaque waiting to be scraped away. It is a living, organized microbial community that responds to its environment. Full-potential hygienists need to understand how biofilm matures, how its behavior changes, how local conditions shape it, and how the host responds. Phase-contrast microscopy can help patients see the activity within their own biofilm. Salivary,
microbial, inflammatory, and halitosis testing can add useful information about oral ecology and disease activity. These tools should not be used to frighten patients or promote indiscriminate microbial killing. They should help us personalize care, measure progress, and guide clinical decisions.

Our goal is not to sterilize the mouth. It is to support a balanced oral ecosystem, reduce destructive activity, strengthen host resilience, and create conditions that favor health.

The Dental Hygienist as a Clinical Investigator

The medical history should not be a form the patient completes and the hygienist quickly initials. It is one of our most valuable investigative tools. A meaningful review explores new medications, sleep quality, fatigue, hormonal changes, digestive concerns, reflux, autoimmune conditions, blood sugar, nutrition, stress, salivary changes, frequent infections, and difficulty healing. More importantly, it looks for connections. Did the bleeding begin after a medication change? Did caries activity increase during perimenopause? Did dry mouth appear after the patient began taking a sleep aid? Could clenching be related to airway instability? Could persistent acid damage be related to reflux? The medical history should be a conversation, not a checkbox.

Dental hygienists should also become familiar with common laboratory findings that may provide context for oral changes. Blood sugar, vitamin D, iron status, thyroid function, inflammatory markers, hormonal shifts, and nutrient deficiencies may help explain bleeding, dry mouth, caries activity, bone loss, fatigue, poor healing, or recurrent inflammation. This is not about diagnosing medical conditions. It is about recognizing patterns, communicating clearly, and collaborating appropriately.

Oral Cancer Screening as Essential Prevention

A comprehensive assessment must include a careful extraoral and intraoral cancer screening. This is more than a quick look at the lateral borders of the tongue. It includes the lips, face, neck, lymph nodes, skin, oral mucosa, floor of the mouth, palate, oropharyngeal region, tongue, and gingival tissues, with attention to changes in color, texture, symmetry, mobility, sensation, and healing.

Hygienists should ask about persistent sores, unexplained bleeding, difficulty swallowing, voice changes, numbness, neck masses, ear pain, and lesions that have not resolved within two weeks. Risk factors such as tobacco, vaping, cannabis use, alcohol, HPV exposure, immune suppression, sun exposure, age, and previous cancer history should be considered. Still, no patient should be assumed to be low risk. Careful documentation, photography when appropriate, timely reevaluation, and prompt referral may be lifesaving. Oral cancer screening is a fundamental expression of prevention and early detection.

Dental Hygienist as Airway, Breathing, and Sleep Advocate

Breathing is foundational to health, yet it is still frequently overlooked during the dental hygiene appointment. Mouth breathing dries the oral tissues, changes the protective qualities of saliva, encourages plaque accumulation, and may increase the risk of inflammation, caries, sensitivity, and halitosis. It can also be connected to sleep-disordered breathing, clenching, daytime fatigue, altered growth and development, and reduced production of nitric oxide through the nasal passages.

Dental hygienists are ideally positioned to recognize the clues. Open-mouth posture, dry or inflamed tissues, scalloped tongues, enlarged tonsils, narrow arches, crowding, wear patterns, tongue restrictions, and poor resting oral posture all invite us to look more deeply. Questions about snoring, restless sleep, morning headaches, difficulty concentrating, waking throughout the night, daytime fatigue, and awakening with a dry mouth may uncover concerns that would otherwise remain hidden. These observations are not a diagnosis, but they are valuable pieces of the patient’s biological story.

Our role is to identify risk, document what we see, educate the patient, and refer appropriately. When we understand airway health, nasal breathing, sleep, and oral posture, we begin to see the mouth not as an isolated collection of teeth, but as part of a larger biological system. We recognize that dry mouth may be connected to open-mouth breathing, that clenching may be an attempt to stabilize an unstable airway, and that chronic inflammation may be influenced by fragmented sleep and the body’s inability to fully rest, regulate, and repair.

This is also where we must challenge ourselves as a profession. Dental hygiene school gives us an essential foundation, but it was never meant to be the end of our education. Our patients deserve clinicians who continue to grow as the science grows. Expanding our knowledge into myofunctional disorders, nasal breathing, airway development, sleep-disordered breathing, and restorative sleep is an investment in our patients, in ourselves, and in the future of dental hygiene. We cannot wait for someone else to hand us permission to become more knowledgeable, more observant, or more valuable.

When we invest in advanced education, we expand what we are capable of seeing. We ask better questions, recognize patterns sooner, collaborate more effectively, and help patients understand connections they may have struggled with for years. This is how dental hygienists become true oral health coaches, prevention specialists, clinical investigators, and trusted members of the interdisciplinary healthcare team. The future of our profession will be built by hygienists who believe they are worth investing in and who understand that learning is not something we finish. It is how we continue to reign.

The Dental Hygienist as a Health Coach

Knowing what a patient needs is not the same as helping the patient achieve it. Patients may be overwhelmed, exhausted, confused, afraid, physically unable to complete a complicated routine, or uncertain about where to begin. Better care requires better coaching.
Hygienists need to ask meaningful questions, listen without judgment, understand the patient’s priorities, explain disease in accessible language, and break recommendations into manageable steps.
Handing a patient six new products and a long list of instructions may feel comprehensive, but it often
reduces the likelihood of success. The hygiene appointment should be a partnership rather than a lecture. Progress should be measured, celebrated, and adjusted when the plan is not working. Sometimes the patient is not failing treatment. The treatment plan is failing the patient. Supporting healing means meeting patients where they are and helping them take the next achievable step.

The Dental Hygienist as an Oral-Systemic Care Partner

The mouth does not function separately from the rest of the body. Oral inflammation, saliva, hormones, sleep, breathing, metabolic health, nutrition, medications, stress, and nervous system regulation are interconnected. Dental hygienists work at the intersection of dentistry, prevention, and whole-person health.
We may be the first provider to recognize severe dry mouth, unexplained bleeding, persistent inflammation, recurrent caries, poor healing, reflux-related damage, sleep-disordered breathing, medication effects, abnormal oral development, or halitosis that requires further investigation. Our role is to notice, document, educate, and refer.

This requires confident communication with dentists, physicians, nurse practitioners, pharmacists, sleep professionals, nutrition professionals, myofunctional therapists, physical therapists, and other members of the healthcare team. The mouth can reveal important clues about overall health, and hygienists must be prepared to connect those clues with appropriate care.

Dental Hygienist as Entrepreneur

The future of dental hygiene must also include entrepreneurship, ownership, and independent practice. In Colorado and Maine, dental hygienists have pathways to own and operate independent dental hygiene practices. These models recognize that hygienists possess valuable clinical knowledge and can deliver preventive and periodontal care directly to the public, while referring patients to dentists and other healthcare professionals when needs extend beyond their scope. In Washington State, we do not yet have unrestricted independent practice, but experienced dental hygienists may be employed, contracted, or work under lease agreements with designated healthcare facilities, including hospitals, nursing homes, home health agencies, group homes, public health facilities, community health centers, tribal clinics, and senior centers. Within these settings, they may provide specified dental hygiene services without on-site dental supervision. These opportunities represent more than alternative employment. They require us to believe in ourselves and in the value of our profession.

Dental hygienists are educated clinicians, prevention specialists, investigators, teachers, health coaches, and advocates. We have something meaningful to offer the public. Independent practice may begin with changes in legislation, but it also begins within us, with the confidence to recognize that our knowledge has value, our care changes lives, and we are worthy of creating practices, programs, and businesses around the services we are uniquely prepared to provide.

What Could the Future Hygiene Appointment Look Like?

The future hygiene appointment should not look the same for every patient. One patient may need intensive periodontal therapy and biofilm assessment. Another may need a caries investigation focused on saliva, reflux, and dry mouth. Another may need airway screening and referral. A patient with persistent halitosis may require tongue biofilm management, salivary support, periodontal evaluation, or microbial testing. A patient experiencing menopause may need help understanding how hormonal changes, medications, sleep disruption, stress, and dry mouth are altering the oral environment. A child with crowding and open-mouth posture may need evaluation of breathing, tongue function, facial growth, and development. A patient with continued periodontal inflammation may need investigation of blood sugar, smoking, nutrition, medications, sleep, airway, stress, hormonal changes, or immune function, not simply another round of instrumentation.

Personalized care requires us to move beyond the idea that every patient should receive the same appointment because the schedule says “prophy.” The appointment should be based on the patient’s biology, risk, disease activity, goals, and capacity for healing. Some patients need treatment, some need testing, some need coaching, and some need referral. Many need a thoughtful combination of all four.

Practicing to the Full Potential of Our Licensure

Practicing to our full potential does not mean stepping outside our scope. It means understanding our scope, pursuing additional education, applying sound clinical judgment, documenting carefully, and collaborating appropriately. State practice acts differ, and every hygienist must know the laws and regulations that apply where they practice.

There is already so much we can do. We can assess more thoroughly, ask better questions, strengthen periodontal and caries protocols, use testing to replace assumptions, teach patients to understand their biology, refer earlier, and document the value we provide. We can evaluate saliva, breathing patterns, medication effects, biofilm activity, dry mouth, diet, halitosis, inflammation, and healing response. We can become the prevention specialists our healthcare system needs.

Full-potential practice also requires dental offices to value the hygienist’s time, education, and clinical judgment. Comprehensive care cannot be delivered in an appointment structured only around speed and production. Hygienists need time to investigate, educate, coach, document, and reevaluate. To Let Purple Reign, we must advocate for schedules, systems, fees, and practice models that support meaningful preventive care.

The Future of Dental Hygiene Is BioLogical

The future of dental hygiene is not about abandoning instrumentation, periodontal therapy, or traditional preventive care. It is about placing those essential services within a larger model of personalized, biological care. This model sees the whole patient, investigates why disease is occurring, addresses the trigger, supports the host terrain, and values prevention as highly as treatment.
Removing calculus, disrupting biofilm, applying a remineralizing product, or recommending a new home-care tool may all be important, but these interventions cannot stand alone. We must also consider whether the patient has the saliva, nutrition, airway, sleep, metabolic stability, immune balance, nervous system regulation, and healing capacity needed to respond. Otherwise, we may repeatedly manage signs of disease without changing the conditions that allow it to persist.

Dental hygienists are uniquely positioned to uncover these connections. We can stop treating every episode of gingival bleeding as simply a brushing problem, every cavity as simply a sugar problem, every periodontal pocket as simply a calculus problem, and every dry mouth as merely an inconvenience. Instead, we can ask what the body may be communicating through the mouth and what this patient needs in order to move toward health.

Dental Hygiene as a Global Movement

Dental hygiene began as a bold idea in 1913, when Dr. Alfred Fones opened the first dental hygiene school in Bridgeport, Connecticut. More than a century later, that idea has grown into an international profession.

At the 2026 International Symposium on Dental Hygiene in Milan, 46 countries were represented—each bringing different cultures, challenges, practice models, and possibilities to one global conversation. The symposium brought dental hygienists together from around the world to exchange ideas and advance the relationship between oral and general health.

What struck me was not only how far dental hygiene has traveled, but how much potential still lies ahead. When hygienists across borders share knowledge, challenge outdated limitations, and step fully into prevention, investigation, education, and leadership, the impact reaches far beyond one operatory—or even one country.

Oral disease knows no borders, and neither should progress.

Together, the global dental hygiene community has the opportunity to level up—to elevate care, strengthen prevention, and improve health around the world.

Purple is no longer simply the color of our profession. It is the banner of a worldwide movement ready to rise.

Let Purple Reign

Dental hygienists do not need a smaller role as dentistry changes. We need a clearer, stronger, and more fully developed role. We are prevention specialists, periodontal therapists, biofilm scientists, clinical investigators, health coaches, airway and breathing advocates, and oral-systemic care partners. We are healthcare professionals with the opportunity to recognize disease earlier, investigate more deeply, personalize care, and help patients create the conditions necessary for healing. The future of dental hygiene is not doing less. It is seeing more, understanding more, and preventing more effectively. It is time to move beyond simply managing disease, to stop allowing our profession to be defined by a polishing cup, and to practice to the full potential of our education, licensure, and clinical wisdom. It is time to support the patient’s healing journey.

Warmly,

Barbara Tritz

Queen of Dental Hygiene and Champion of the Future of Dental Hygiene

Now, go forth and let Purple Reign!
