Guided Biofilm Therapy (GBT) in Singapore: The Gentle Evolution of Airflow Cleaning
A gentler, smarter, Swiss-developed way to clean your teeth — available at Dentalis, Tanjong Pagar.
Most clinics talk about “Airflow cleaning.” At Dentalis, we go further. We use the authentic Guided Biofilm Therapy (GBT) protocol — an evidence-based, 8-step system designed by EMS Switzerland to remove plaque (biofilm), stains and bacteria in a way that’s precise, comfortable, and safe even for sensitive teeth, implants, and braces.
This isn’t just a quick polish. It’s preventive dentistry, elevated.
What Is Guided Biofilm Therapy?
Guided Biofilm Therapy (GBT) is a structured dental hygiene protocol that starts by showing you exactly where bacteria are hiding — and then removes them in a targeted, minimally invasive way.
Instead of scraping every tooth “just in case,” we first disclose biofilm with a harmless dye. Once the pink/purple areas appear, your clinician knows exactly where to clean. That’s the “guided” part.
GBT was developed to:
-
protect teeth and gums,
-
improve comfort,
-
and make professional cleaning more effective over the long term.
It’s especially helpful for patients who want their visits to be calm, sensory and gentle — not clinical, rushed, or noisy.
Airflow Cleaning vs True GBT — What’s the Difference?
Many people in Singapore have heard of Airflow because some clinics use the AirFlow machine to spray powder and water to remove stains. That’s good — but it’s not the full GBT protocol.
Here’s the key distinction:
-
Airflow cleaning → usually 1 step (spray to clean and polish)
-
Guided Biofilm Therapy → 8-step protocol (diagnose → disclose → AirFlow → PerioFlow → ultrasonic finishing → protect)
Put simply: Airflow is a tool. GBT is the full science.
At Dentalis, we follow the complete GBT sequence with EMS technology, so you’re not just getting “a nicer cleaning” — you’re getting the version that is actually designed to preserve enamel, protect implants and slow down gum disease.
The 8-Step GBT Experience at Dentalis
We’ve tailored the international GBT protocol to fit the Dentalis “Art of Care” experience.
1. Assess
Your dentist or hygienist first examines your gums, restorations and risk areas. This makes the treatment personalised, not generic.
2. Disclose
A harmless dye is applied to your teeth. This stains biofilm so you and your clinician can see where bacteria have accumulated — between teeth, around braces, under the gumline.
3. Motivate
Because you can now see what’s missed at home, we’ll show you how to brush and clean more effectively. This makes each GBT visit educational, not just procedural.
4. AirFlow®
Using warm water, air and fine erythritol powder, the EMS AirFlow system gently removes biofilm and light stains from the tooth surface — with no scraping and minimal sound.
5. PerioFlow® (if needed)
For patients with deeper gum pockets, implants or orthodontic appliances, we use PerioFlow to clean below the gumline without damaging the surface.
6. Piezon® PS Ultrasonic
Only where absolutely necessary, we finish with an ultra-gentle ultrasonic tip to remove any remaining calculus. Because we disclosed first, we don’t over-clean.
7. Check
Your clinician verifies that all stained areas are now clean — this is what makes GBT so thorough.
8. Protect
A protective or remineralising application is placed to support long-term gum and enamel health.
All of this is done in a calm, art-led, shophouse setting — so the experience doesn’t feel medical, but restorative.
Why Choose GBT over Traditional Scaling & Polishing or “Airflow Cleaning”?
Most clinics that advertise “Airflow cleaning” use only the spray step of GBT. Dentalis offers the complete protocol, combining science, artistry, and precision. That means a deeper clean, gentler touch, and measurable improvement in gum health.
Benefits of Guided Biofilm Therapy
-
More precise than standard scaling
We clean what we can see — thanks to disclosing. This actually reduces over-treatment and effectively removes dental biofilm and plaque, even in hard-to-reach areas.
-
Brighter, cleaner finish
GBT removes surface stains from coffee, tea and lifestyle habits, restoring natural lustre.
-
Gentle, almost pain-free:
Pain-free comfort – no sharp instruments on every tooth. Many patients describe it as “a soft jet wash.”
-
Naturally brighter teeth
Removes surface stains from coffee or tea
-
Safer for high-value Dental Restorations
Ideal for cleaning around braces, implants, and veneers without causing damage.
-
Better for gum health
Regular use can help prevent gum inflammation and early-stage gum disease - gingivitis, periodontitis and peri-implantitis.
. -
Scientifically proven
Removes > 99 % of biofilm (E M S data)
Who Is GBT Ideal For?
GBT is designed for patients who want efficacy without trauma.
It’s especially suitable for:
-
People with sensitive teeth or receding gums
-
Patients with implants, veneers, crowns or composite bonding
-
Patients wearing Invisalign or braces (biofilm builds fast around attachments and brackets)
-
Patients with a history of gum issues who need gentler but more frequent cleaning
-
Anyone who disliked traditional “scraping” and wants a modern alternative
Because GBT uses low-abrasion Swiss powder and warm water, it is kinder to enamel and soft tissues than conventional polishing.
