Oral hygiene goes beyond just having a bright smile—it's crucial for your overall health. One of the most effective and patient-friendly methods of maintaining excellent oral health is Guided Biofilm Therapy (GBT).

This innovative approach helps in the prevention and treatment of dental issues by focusing on biofilm management, ensuring a thorough and comfortable cleaning experience.



What is Biofilm?


Biofilm is a thin, sticky layer of bacteria that forms on the surfaces of your teeth and gums. While biofilm may seem harmless initially, if left untreated, it can harden into plaque and tartar, contributing to dental issues such as:

  • Cavities

  • Gum disease (gingivitis and periodontitis)

  • Bad breath (halitosis)

  • Tooth loss in severe cases


Biofilm is not always easy to remove through regular brushing and flossing, which is why professional intervention is sometimes necessary.


What is Guided Biofilm Therapy (GBT)?



Guided Biofilm Therapy is a modern, minimally invasive dental cleaning technique that focuses on removing biofilm from the teeth, gums, and other oral surfaces. Using advanced technology, GBT is more effective and less invasive than traditional cleaning methods. It’s a personalized and step-by-step protocol designed to address biofilm before it causes serious dental problems.

The 8-Step GBT Protocol



Guided Biofilm Therapy follows an 8-step process that ensures your teeth and gums are cleaned safely and efficiently:

  1. Assessing Oral Health: A comprehensive examination of your oral condition, including identifying areas with high biofilm accumulation.

  2. Disclosing Biofilm: A special dye is applied to your teeth to make the biofilm visible, allowing both you and the dentist to see areas that need extra attention.

  3. Motivation and Education: Your dentist will explain how biofilm develops and provide personalized tips for improving oral hygiene at home.

  4. Airflow Cleaning: Using a gentle stream of air, water, and powder, biofilm and stains are removed from your teeth and gums.

  5. Perioflow Cleaning: For deeper cleaning, particularly around the gums, a finer powder is used to clean biofilm from periodontal pockets.

  6. Piezon Ultrasonic Scaling: Any remaining plaque or tartar is carefully removed using an ultrasonic device, ensuring a thorough cleaning without damaging the tooth surface.

  7. Final Check: A final inspection is done to ensure all biofilm and plaque have been removed.

  8. Polishing and Protection: Your teeth are polished, and if necessary, a fluoride treatment is applied to protect them from future cavities.


The Benefits of Guided Biofilm Therapy

1. Comfortable and Gentle GBT uses state-of-the-art technology to ensure your comfort. The Airflow and Piezon technologies are gentle, reducing the need for scraping and minimizing discomfort. This makes it an excellent choice for patients with sensitive teeth or gums.

2. Effective Plaque and Biofilm Removal By targeting biofilm specifically, GBT ensures more thorough cleaning than traditional methods. The disclosing dye allows both the dentist and the patient to see the biofilm, making it easier to remove and track improvement over time.

3. Minimally Invasive The non-abrasive nature of GBT preserves the integrity of your teeth and gums. The treatment is focused on biofilm removal without unnecessarily damaging the enamel or soft tissues.

4. Safe for All Patients Whether you have braces, dental implants, crowns, or other restorations, GBT is safe and effective. It’s a suitable cleaning method for children, adults, and seniors alike.

5. Prevention of Future Issues By addressing biofilm early on, GBT helps prevent more severe dental problems such as cavities, gum disease, and periodontal complications. Regular GBT sessions can significantly enhance your long-term oral health.


Who Can Benefit from Guided Biofilm Therapy?

Almost everyone can benefit from Guided Biofilm Therapy, especially if you:

  • Struggle with regular plaque buildup

  • Have a history of gum disease

  • Wear braces, dental implants, or crowns

  • Experience sensitivity during traditional cleanings

  • Want to enhance your preventive care routine


How Often Should You Have GBT?


For most patients, GBT is recommended during your regular dental cleanings every six months. However, depending on your oral health condition, we may suggest more frequent sessions to maintain optimal oral health.


Guided Biofilm Therapy offers a gentle, effective, and personalised way to protect your smile from the harmful effects of biofilm. With its minimally invasive and patient-focused approach, GBT ensures that your dental cleanings are more comfortable and thorough, helping you achieve long-lasting oral health.
