A New Standard in Preventive Dentistry
Guided Biofilm Therapy represents one of the most significant advances in preventive dental care in decades. It protects healthy teeth and gums against decay, gingivitis, and periodontal disease, and it plays an active role in treating these conditions once they have developed.
What distinguishes GBT from a regular dental cleaning is its technology. In place of extensive manual scaling and abrasive polishing pastes, GBT uses a warm, controlled stream of air, water, and ultra-fine powder to remove biofilm gently and thoroughly, including below the gumline.
Any remaining calculus is addressed with a slim, minimally invasive ultrasonic instrument. The result is a cleaning that is more precise, more comfortable, and more respectful of the tooth surface than was previously possible.
What Is GBT?
Guided Biofilm Therapy — GBT — is a systematic, evidence-based dental cleaning protocol developed by EMS (Electro Medical Systems), a Swiss company that has been at the forefront of dental technology for over four decades. It is now used by more than 7,000 certified dental practices worldwide.
The word "guided" is the key. For the first time, the cleaning appointment is not a general sweep of the mouth — it is a targeted, precise response to a visible map of what is actually living on your teeth. Before any instrument touches a tooth surface, biofilm is made visible with a disclosing agent, and what follows is directed by exactly what is found.
At Dr. Rossinski Dental Health, we adopted GBT because it aligns with something we have believed for a long time: that the mouth is a living ecosystem, not a collection of surfaces to be mechanically maintained. GBT treats it accordingly.
What Is Biofilm?
Most patients have heard of plaque. Fewer have heard of biofilm — and the distinction matters enormously.
Biofilm is not the same thing as plaque or calculus. Calculus is mineralized — hardened deposits of calcium and phosphate that have crystallized onto the tooth surface over time. Plaque is the soft, sticky film most people are familiar with from brushing. Biofilm is something more fundamental than either. It is a living, constantly reorganizing community of bacteria — and fungi, and viruses — that forms on every tooth surface within hours of a cleaning, organizing itself into structured layers, communicating through chemical signals, producing acids, and generating inflammatory byproducts that drive the progression of both decay and gum disease.
What makes biofilm particularly challenging is that it is largely invisible to the naked eye. It cannot be seen, only inferred — until now. And treating what you cannot see produces unpredictable results.
Biofilm is also remarkably resilient. Embedded in a self-produced protective matrix, it resists rinsing, resists saliva, and in its more established forms resists standard cleaning instruments. Left undisturbed, it matures, diversifies, and becomes increasingly difficult to disrupt. When its harmful species begin to outcompete the beneficial ones — a state known as dysbiosis — it becomes the biological engine behind most oral disease.
Traditional dental cleaning addresses the visible consequences of biofilm. GBT addresses biofilm itself.
How Is GBT Different From a Traditional Cleaning?
The conventional dental cleaning has not changed fundamentally in decades. An instrument scrapes the tooth surface. A rubber cup spinning with abrasive paste polishes what remains. Calculus is removed where it is found. The patient rinses and leaves.
This approach is effective within its own logic — and that logic has a significant blind spot. It addresses calculus, the end product of long-standing bacterial activity, but does not meaningfully address biofilm, the living community that produced it. After the appointment, the same bacterial environment that established itself before largely reestablishes itself after — because the underlying conditions that allowed it to thrive have not changed.
There is also a cumulative cost to the tissues themselves. Abrasive polishing pastes remove a thin layer of fluoride-rich outer enamel with every appointment. Metal instruments can remove cementum — the biological layer covering the root that contributes to the tooth's attachment to surrounding bone. These are small disruptions individually. Over years and decades of regular cleaning appointments, they add up.
GBT takes a different approach entirely. It makes biofilm visible before touching a single tooth. It removes biofilm using a warm water and erythritol powder system that is non-abrasive, noninvasive, and gentle on every surface it cleans. It reaches below the gum line into periodontal pockets that traditional polishing has never accessed. And it removes calculus only after the biofilm has been fully cleared — using ultrasonic technology that engages precisely where calculus is detected rather than running uniformly across every surface.
Less disruption. More precision. A biological environment that is better positioned to heal and maintain itself between visits.
Why GBT Fits Our Holistic Approach
At Dr. Rossinski Dental Health, technology is adopted when it offers genuine clinical value — not because it is new, but because it is better. GBT earns its place on both counts.
The erythritol powder at the heart of the AIRFLOW® system is a naturally occurring sugar alcohol found in small amounts in certain fruits. It is non-toxic, non-cariogenic, and has been shown to have mild antibacterial properties against the specific organisms that drive tooth decay. It is, in a meaningful sense, one of the least chemically intrusive materials that could be used for a cleaning — a far cry from the flavoring agents, sodium lauryl sulfate, and variable-quality additives found in traditional polishing pastes.
The broader philosophy is equally aligned. GBT minimizes disruption to healthy tissue. It preserves enamel, dentin, and cementum rather than abrading them appointment after appointment. It treats the oral environment as a living ecosystem to be understood and supported, rather than a set of surfaces to be mechanically processed.
There is also a natural connection to two other pillars of our preventive approach. GBT creates the cleanest possible terrain for beneficial bacteria to recolonize after an appointment — making it the ideal preparation for targeted oral probiotic therapy. And when combined with saliva testing, which reveals exactly which organisms are driving inflammation or decay in a patient's unique microbiome, GBT becomes part of a coordinated biological strategy rather than a standalone procedure. The cleaning prepares the terrain. The probiotics, guided by saliva testing, help determine what grows there next.
Who Benefits Most
GBT is suitable for virtually all patients. It is especially meaningful for:
Patients with sensitivity — warm water and non-abrasive powder make GBT significantly more comfortable than traditional cleaning for those with exposed dentin or inflamed gum tissue
Patients with implants — erythritol powder is safe on titanium surfaces and surrounding peri-implant tissue, where metal instruments can cause microscopic damage
Patients with veneers, crowns, or orthodontic appliances — GBT cleans without risking scratches or disruption to delicate restorations and surfaces
Patients with active or historical periodontal disease — the PERIOFLOW® tip
reaches into pockets that have never been addressed by a polishing instrument before
Patients with dental anxiety — the absence of cold water, abrasive paste, and the characteristic scraping of metal on tooth changes the experience entirely for many patients who have dreaded cleanings for years
Patients interested in oral probiotics and saliva testing — GBT prepares the oral environment for the most effective possible follow-through with personalized microbiome support
Children and first-time patients — the gentleness and comfort of GBT makes it an ideal introduction to professional dental care

Frequently Asked Questions
01
Is GBT painful?
For most patients, GBT is the most comfortable professional cleaning they have ever experienced. The warm water, non-abrasive powder, and targeted approach eliminate many of the sensations — cold, scraping, abrasive paste — that make traditional cleanings uncomfortable. Clinicians who have adopted GBT report that the need for topical anesthetic during cleanings drops dramatically, in some practices to essentially zero.
02
How long does a GBT appointment take?
A GBT appointment is typically similar in length to a traditional cleaning — though the experience feels very different. The additional steps, particularly disclosing and targeted biofilm removal, are efficient and do not significantly extend the appointment time.
03
How often should I have GBT?
That depends on your individual oral health profile. Most patients follow a recall schedule of every six months, consistent with standard preventive care. Patients with active periodontal disease, a history of implants, or elevated caries risk may benefit from more frequent appointments. Your hygienist will recommend the right interval for you at your appointment.
04
Is GBT safe for implants and veneers?
Yes. The erythritol powder used in GBT is safe on titanium implant surfaces, porcelain veneers, crowns, and other restorations — surfaces that traditional polishing instruments can microscopically scratch or disrupt. GBT is in many ways the preferred cleaning approach for patients with complex restorative work.
05
Can children have GBT?
Yes. GBT is suitable for patients of all ages. Its gentleness and comfort make it particularly wellsuited for children, and the disclosing step can be a genuinely engaging educational tool for young patients learning to understand their oral health.
06
How is erythritol powder different from regular polishing paste?
Traditional polishing paste contains abrasive particles ranging from 40 to 200 micrometers in diameter, along with flavoring agents, sodium lauryl sulfate, and other additives. Erythritol powder particles are 14 micrometers — smaller than a human red blood cell — and have been shown not to scratch enamel, dentin, or cementum. It is also a naturally occurring compound with mild antibacterial properties, making it one of the most biocompatible cleaning agents available.
07
Can GBT be combined with saliva testing and probiotics?
Yes — and we believe the combination is particularly powerful. GBT removes dysbiotic biofilm thoroughly and precisely, creating a clean environment that is ideal for beneficial bacteria to recolonize. When oral probiotics are then introduced based on saliva testing results — which
identify exactly which organisms are present and which are driving disease — the effect is cumulative. The cleaning prepares the terrain. The probiotics help shape what grows there next. Together they represent a genuinely different approach to long-term oral health.
08
Is GBT covered by my insurance?
Most PPO dental insurance plans we accept cover GBT the same way they cover traditional cleanings. In most cases, you receive a significantly more advanced standard of care at no additional out-of-pocket cost. Our team will verify your specific coverage before your appointment so there are no surprises.
