TLDR
Guided Biofilm Therapy (GBT) is an 8-step clinical protocol developed by EMS Switzerland that removes plaque biofilm more thoroughly and comfortably than conventional scaling. Unlike standalone Airflow cleaning, GBT first makes bacteria visible with a disclosing dye, then removes it precisely using warm water and erythritol powder — safe for implants, braces, veneers, and sensitive teeth. A full session takes 30–45 minutes and is available at Dentalis Tanjong Pagar as The Dentalis Spa.

Welcome to Guided Biofilm Therapy (GBT) — the advanced, science-led protocol redefining what "clean" means in modern dentistry. Designed in Switzerland by EMS, GBT offers a gentler, smarter and more effective way to remove plaque (biofilm) while protecting your teeth, gums and restorations.
Understanding Guided Biofilm Therapy (GBT)
Most people think of dental cleaning as the familiar scaling and polishing routine — a whirring sound, metal instruments and the occasional wince. GBT changes that completely.
Guided Biofilm Therapy is an evidence-based eight-step protocol that uses advanced AirFlow and PerioFlow technology to remove plaque precisely and comfortably. Instead of scraping blindly, the dentist first makes the invisible visible by staining bacterial biofilm with a harmless dye. What follows is targeted cleaning — only where necessary, and only as gently as needed.
The 8-Step GBT Protocol
01
Assess
Your dentist examines your teeth and gums to understand your overall oral health.
02
Disclose
A harmless dye highlights where plaque is hiding — making the invisible visible.
03
Motivate
You'll see those areas and learn how to improve daily brushing and flossing tailored to your pattern.
04
AirFlow
A gentle mist of warm water and fine powder removes visible plaque and stains — no scraping.
05
PerioFlow
A slimmer nozzle cleans deeper under the gums and around braces or implants.
06
Piezon
Any remaining hard deposits are removed with a quiet ultrasonic scaler.
07
Check & Protect
The dentist checks every surface and applies fluoride for added protection.
08
Recall
You'll get a personalised schedule to keep your teeth healthy between visits.
The result? A truly complete clean — smoother teeth, fresher breath, and visibly healthier gums without discomfort.

Airflow Cleaning vs Guided Biofilm Therapy — What's the Difference?
Many patients in Singapore already recognise "Airflow cleaning." It's often promoted as a comfortable alternative to scaling. But Airflow alone ≠ GBT.
Why the Confusion Happens
Airflow refers to the device — a handpiece that sprays air, water, and fine powder to remove plaque. Guided Biofilm Therapy, however, refers to the protocol — the structured clinical method developed by EMS that ensures plaque is fully identified, removed, and verified.
Using Airflow without following the full GBT protocol is like using a camera without adjusting focus or lighting. You can take a picture, but it won't be perfect.
Analogy That Makes It Clear
Owning an Airflow device doesn't make a clinic GBT-certified — just like owning a stethoscope doesn't make someone a cardiologist. At Dentalis, we follow the complete Swiss-designed GBT protocol, not just the tool. That's how we ensure every cleaning is equal parts precision, comfort and science.

Why Guided Biofilm Therapy Is the Future of Preventive Dental Care
01
Gentle — Perfect for Sensitive Teeth
No metal scraping, no harsh vibrations. The fine erythritol powder glides over enamel — ideal for receding gums or tooth sensitivity.
02
Scientifically Proven and Clinically Tested
GBT is the result of 30 years of research by EMS Switzerland. Studies show it removes >99% of plaque biofilm while preserving tooth structure.
03
Safe for Implants, Braces, and Veneers
Traditional scaling can scratch delicate surfaces. GBT uses low-abrasion powder safe for titanium, ceramic, and composite materials.
04
Improves Gum Health Long-Term
By eliminating bacterial biofilm early, GBT prevents gingivitis, periodontitis, and peri-implantitis — helping you maintain gum and bone health for years.
05
Comfortable, Quick, and Precise
A complete GBT session typically takes 30–45 minutes, with many patients describing it as "spa-like" rather than clinical.
