GBT is a professional cleaning system that uses a fine stream of air, warm water, and powder particles to remove plaque, stains, and soft deposits from the teeth and gums. It is gentle and effective for maintaining oral hygiene, particularly around restorations and implants.
This system forms part of preventive and maintenance care. It helps support gum health and cleanliness during regular dental visits, with each treatment carried out under professional guidance.
Understanding Guided Biofilm Therapy
Guided Biofilm Therapy (GBT) is a professional cleaning method developed by Electro Medical Systems (EMS) to help manage plaque, or “biofilm,” in a gentle and structured way. It follows a sequence of steps that involve identifying, showing, and removing the bacterial layer that naturally forms on teeth and gums.
Biofilm is a thin, sticky coating that develops on tooth surfaces and around the gums. If it is not cleaned regularly, it can harden into tartar and contribute to gum inflammation or decay. While daily brushing and flossing help control biofilm, some areas in the mouth — especially around fillings, braces, or implants — may still need professional cleaning.
Guided Biofilm Therapy uses Airflow, Perioflow, and Piezon systems to clean teeth and gums carefully. These tools use a mix of air, water, and fine powder to remove buildup while supporting ongoing oral hygiene during regular dental visits.
