How many times have you put off a visit to the dentist for a routine cleaning because of the discomfort caused by traditional methods? Well, the days of „scraping” on your teeth and post-treatment sensitivity are over.
At Dr. Nicolau’s clinic, we are committed to technology that puts patient comfort first. That is why we have adopted the gold standard in dental prophylaxis: Guided Biofilm Therapy (GBT). More than just a cleansing treatment, GBT is a state-of-the-art therapeutic experience.
What exactly is GBT?
Guided Biofilm Therapy is a systematic, evidence-based hygiene protocol developed by Swiss experts at EMS. Unlike conventional scaling, GBT focuses on the number one enemy of oral health: bacterial biofilm (dental plaque).
Biofilm is an invisible film of bacteria that adheres to the surface of the teeth and gums. If it is not removed properly, it leads to the development of cavities, gingivitis, and, finally, periodontal disease.
Why is GBT the „new era” of sanitation?
If you're wondering how this protocol differs from traditional dental cleaning (ultrasonic scaling and professional brushing), here are the main advantages:
1. Visualizing the Enemy (Coloring the Board)
At GBT, we don’t work „by guesswork.” The first step is to apply a staining solution that highlights the biofilm. This way, both the dentist and you can see the areas that require extra attention. This step also plays a key educational role in helping you maintain good oral hygiene at home.

2. AirFlow® Technology
Instead of sharp metal tools that are overused, GBT uses technology AirFlow®. It emits a controlled stream of warm water and a special powder (erythritol) that removes biofilm and surface stains (coffee, tobacco, wine) even from hard-to-reach areas, without coming into direct contact with the tooth.

3. Maximum Comfort (Water Heating)
One of the biggest advantages is the water temperature. Our devices heat the water, eliminating that unpleasant sensation of „sensitivity to cold” that many patients experience during traditional dental scaling.
4. Safety for Implants and Veneers
GBT is the only sanitization method that effectively yet gently cleans prosthetic restorations, dental implants, and orthodontic appliances without scratching ceramic or metallic materials.
The 8 Steps of the GBT Protocol
At Dr. Nicolau's clinic, we strictly follow the Swiss protocol to ensure impeccable results:
- Evaluation: Diagnosing the condition of the gums and teeth.
- Highlight: Staining the biofilm for maximum visibility.
- Reasoning: Personalized tips for brushing your hair at home.
- AirFlow®: Removal of biofilm and fresh stains.
- PerioFlow®: Deep cleaning of periodontal pockets (if necessary).
- Piezon® No Pain: Use ultrasound only where there is hard tartar, with technology that adjusts to the pressure applied.
- Control: A final check to make sure all the biofilm has been removed.
- Schedule: Schedule your next visit based on your individual risk.
Frequently Asked Questions
Yes, definitely. GBT is specifically designed to eliminate discomfort. Because it uses AirFlow® technology (a gentle stream of warm water and fine powder) and Piezon® No Pain technology, the pressure on the tooth is minimal, and sensitivity is virtually nonexistent. It’s the ideal method for patients with sensitive teeth or a fear of the dentist.
A complete appointment lasts, on average, between 30 and 60 minutes, depending on the complexity of the case (such as whether the patient has braces, implants, or heavy tartar buildup). Although the protocol consists of 8 steps, they are carried out smoothly and efficiently.
The general recommendation is twice a year (every 6 months). However, for patients with periodontal disease, dental implants, or orthodontic appliances, the specialist at Dr. Nicolau’s clinic may recommend more frequent visits—every 3–4 months—to prevent inflammation.
Absolutely. GBT is the safest and most effective method of oral hygiene for people who wear braces. The AirFlow® jet reaches areas that are inaccessible to a toothbrush or traditional cleaning tools (around the brackets and under the wires), preventing cavities and white spots from forming after the braces are removed.
Yes, GBT is considered the gold standard for implant maintenance. The special powder used (erythritol) cleans the surface of the implant and the crown without scratching the metal or ceramic, thereby protecting the long-term integration of the implant and preventing peri-implantitis.
