Painless dental hygiene: the GBT method

Guided Biofilm Therapy makes teeth cleaning gentle and effective: no aggressive instruments, just air, ultra-fine powders and an 8-step protocol.

If the idea of a dental cleaning makes you shiver — the noise, the discomfort, the sensitivity — good news: with Guided Biofilm Therapy (GBT) professional hygiene has become a gentle, almost pleasant treatment.

What biofilm is

Dental plaque is a biofilm: an organised film of bacteria that adheres to teeth and gums and is the main cause of decay, gingivitis and periodontitis. The problem? It is largely invisible.

The GBT protocol

  1. Assessment of teeth and gums.
  2. Biofilm disclosure: a colouring agent makes plaque visible, so treatment focuses where needed.
  3. Motivation: we show you where your toothbrush doesn't reach.
  4. Air polishing: a jet of air, warm water and ultra-fine powders gently removes biofilm and stains, even below the gum line.
  5. Targeted instrumentation only on residual tartar.
  6. Final check, fluoride and personalised advice.

Advantages over traditional cleaning

  • Comfort: no prolonged scraping or unpleasant noises
  • Precision: the disclosing agent guides treatment where plaque really is
  • Gentleness on enamel, gums, implants and braces
  • Immediate results: smooth, clean, brighter teeth

Prevention is teamwork

Professional hygiene every 6 months is the pillar of prevention — the rest is up to you every day: brushing twice a day, floss or interdental brushes, fewer sugars between meals. Every hygiene session at our practice always includes advice tailored to your mouth.

Book your GBT hygiene session: your smile (and your gums) will thank you.

Frequently asked questions

How often should professional hygiene be done?

On average every 6 months, but the right interval is personal: patients with gingivitis, braces or implants may need more frequent recalls.

Does GBT cleaning hurt?

No: air polishing with ultra-fine powders is gentle on teeth and gums. It also suits those with sensitive teeth or who always found traditional cleaning uncomfortable.

Does GBT also remove coffee and smoking stains?

Yes: the powders effectively remove surface stains, restoring the teeth's natural colour.
