Guided Biofilm Therapy (GBT)
Advanced, Gentle Dental Hygiene at Expressions Dental
At Expressions Dental, preventive care lies at the foundation of long-term oral health. One of the most advanced methods of professional dental cleaning available today is Guided Biofilm Therapy (GBT) — a modern, science-based approach designed to remove harmful bacterial biofilm gently, precisely, and effectively.
Guided Biofilm Therapy represents a significant advancement in preventive dentistry. Instead of relying on traditional scraping methods alone, this innovative system follows a structured protocol that identifies and eliminates dental biofilm — the primary cause of cavities, gum disease, and many other oral health concerns.
What Is Guided Biofilm Therapy?
Biofilm is the underlying cause of many oral health conditions, including:
- Tooth decay
- Gum inflammation and bleeding
- Periodontal disease
- Persistent bad breath
- Complications around implants or orthodontic appliances
How Guided Biofilm Therapy Works
Comprehensive Oral Assessment
Biofilm Detection
A harmless disclosing solution is applied to the teeth to highlight areas where biofilm has accumulated.
Patient Education
Once biofilm is visible, your dental team provides guidance on brushing, flossing, and oral hygiene practices.
Airflow Biofilm Removal
A gentle stream of warm water, air, and ultra-fine powder is used to remove biofilm and surface stains from the teeth, gumline, and hard-to-reach areas.
Subgingival Cleaning
Specialised instruments allow clinicians to safely clean biofilm beneath the gumline and around implants or orthodontic appliances.
Ultrasonic Scaling (If Needed)
Any remaining hardened deposits, such as tartar or calculus, are removed using modern ultrasonic technology.
Final Inspection and Protection
The dentist performs a final check and may apply fluoride or other protective treatments.
Personalised Maintenance Plan
Patients receive recommendations for future hygiene appointments and preventive care.

Guided Biofilm Therapy vs Traditional Dental Cleaning
Guided Biofilm Therapy represents a more modern, preventive-focused approach. By identifying biofilm before treatment and removing it using airflow technology and specialised instruments, clinicians can clean teeth more efficiently while preserving tooth structure and soft tissue health.

What's New in Guided Biofilm Therapy
Research published in the International Journal of Dental Hygiene has shown that Guided Biofilm Therapy using the AIRFLOW® system removes biofilm more effectively and with greater patient comfort than traditional scaling and polishing methods. The approach uses a warm water and erythritol powder spray to gently disrupt bacterial deposits before any instrument touches the tooth surface. Patients in clinical trials consistently reported less sensitivity and discomfort during and after treatment compared to conventional cleaning.
A growing body of clinical evidence, including studies reviewed by the European Federation of Periodontology, supports biofilm-focused protocols as the foundation of modern preventive dental care, since it is the bacterial biofilm on teeth and gums — not tartar alone — that drives gum disease and decay. EMS Dental, the Swiss company behind the AIRFLOW® and PIEZON® technology used in GBT, has continued refining its systems based on clinical feedback to improve safety on implant surfaces and sensitive gum tissue. This makes GBT a well-supported option for patients with implants, orthodontic appliances, or a history of gum disease.
