Guided Biofilm Therapy (GBT) in Ottawa

A Comprehensive Approach to Oral Health

Guided Biofilm Therapy (GBT)

Guided Biofilm Therapy is a systematic protocol for dental biofilm management. This approach focuses on the identification and removal of biofilm—the bacterial layer associated with the development of dental caries, periodontal (gum) disease, and peri-implant concerns.

The GBT Protocol Unlike traditional scaling and polishing methods, the GBT protocol utilizes Airflow® technology. This system uses a controlled stream of air, warmed water, and fine powder to remove biofilm and early-stage calculus from tooth surfaces and soft tissues.

Clinical Objectives of GBT:

  • Efficiency: Designed for the removal of biofilm in hard-to-reach areas, including around orthodontic brackets and dental implants.

  • Patient Comfort: Aims to provide a less invasive cleaning experience by reducing the need for manual or ultrasonic scaling in certain areas.

  • Health Maintenance: Focuses on the preservation of tooth enamel and the health of the surrounding gingival (gum) tissues.

During your hygiene appointment, our team will assess your oral health to determine the most appropriate cleaning methods for your specific needs.

How Guided Biofilm Therapy Works: The 8 Steps of GBT

Steps of gbt protocol

 

Guided Biofilm Therapy follows a precise 8-step clinical protocol designed to provide a complete, comfortable, and personalized cleaning experience.

Step 1 – Assessment

Your dentist begins with a full oral examination to evaluate your teeth, gums, and any restorations or implants. This helps determine your current oral health status and areas that require special attention.

Step 2 – Disclosure

A harmless, colored disclosing agent is applied to reveal the presence of biofilm. This makes plaque visible for both you and your dental professional, creating a clear roadmap for your cleaning.

Step 3 – Motivation

Your dentist will explain where biofilm accumulates and how it contributes to cavities, gum disease, and bad breath. You’ll also receive personalized oral hygiene tips to improve your at-home care routine.

Step 4 – Airflow® Cleaning

Using Airflow® technology, a precise stream of air, warm water, and fine erythritol powder gently removes biofilm, stains, and early calculus from teeth, gums, and hard-to-reach areas. This step is non-invasive, comfortable, and highly effective—perfect for patients with sensitive teeth.

Step 5 – Perioflow® Treatment (if needed)

For patients with gum disease or deep pockets, the Perioflow® nozzle targets and removes biofilm below the gumline and around implants—helping reduce inflammation and maintain healthy gums.

Step 6 – Piezon® No Pain Instrumentation

After biofilm removal, your dentist uses Piezon® technology for precision cleaning. It safely removes any remaining hard deposits (tartar) using ultrasonic vibrations while ensuring a pain-free experience.

Step 7 – Final Check

Your dentist re-examines your mouth to ensure all biofilm and calculus have been fully removed. They’ll also assess your gum health and make any necessary recommendations for ongoing care.

Step 8 – Recall & Follow-Up

Finally, your personalized recall schedule is set to maintain long-term oral health. Regular GBT visits help prevent biofilm reformation and keep your teeth and gums in optimal condition year-round.

Why Patients Love GBT

Guided Biofilm Therapy is designed with a focus on clinical precision and patient comfort. By utilizing the Airflow® system—which employs a warmed mixture of air, water, and fine powder—the need for traditional manual or ultrasonic scaling can often be reduced.

Clinical Considerations:

  • Minimizing Sensitivity: The GBT protocol is intended to be a gentle alternative for patients who experience sensitivity during traditional scaling procedures.

  • Non-Invasive Approach: Because the technology utilizes a kinetic energy stream rather than mechanical scraping for biofilm removal, many patients find the process less intrusive.

  • Post-Treatment: The objective of GBT is to provide a thorough cleaning while minimizing the irritation often associated with traditional hygiene methods.

Every patient’s sensitivity level is unique. Our dental hygiene team will adjust the protocol to ensure your appointment is as comfortable as possible based on your specific oral health status.

The Role of GBT in Preventive Care

Guided Biofilm Therapy is a proactive protocol used to manage plaque and biofilm accumulation. Regular hygiene appointments, incorporating the GBT method, are a foundational component in the management of:

  • Gingival inflammation and periodontal (gum) disease.

  • The accumulation of bacteria that can lead to dental caries (cavities).

  • The long-term maintenance of dental implants and orthodontic appliances.

GBT may be a suitable option for:

  • Patients with a history of gingival inflammation.

  • Individuals undergoing orthodontic treatment (braces or clear aligners).

  • Patients with dental implants, crowns, or bridges.

  • Individuals with a history of tooth sensitivity who require a gentle clinical approach.

A Focus on Long-Term Oral Health The clinical objective of GBT is the thorough removal of biofilm. By managing bacterial levels during regular professional cleanings, we aim to support the stability of your oral health and reduce the risks associated with periodontal complications.

Personalized Dental Care for Every Patient

Every GBT session is customized to your oral health needs. Your dentist can adjust the treatment’s focus and intensity to ensure comfort and effectiveness.

This personalized approach makes GBT ideal for patients of all ages—including children, orthodontic patients, and those with restorations or implants.

Long-Lasting and Cosmetic Benefits

Since GBT removes the root cause of most dental problems—biofilm—it promotes stronger gums, fresher breath, and long-lasting oral health.

It also helps restore the natural brightness of your teeth, enhancing your smile’s appearance. When combined with treatments like teeth whitening or Invisalign®, GBT ensures your results look clean, natural, and healthy.

Guided Biofilm Therapy (GBT): Frequently Asked Questions

What exactly is Guided Biofilm Therapy (GBT)?

GBT is a modern, science-based approach to professional dental cleaning. Instead of traditional scraping, it uses a precise 8-step protocol involving Airflow® technology (a gentle spray of air, warm water, and fine powder) to remove biofilm—the sticky bacteria responsible for cavities and gum disease.

Not at all! In fact, most patients find it incredibly comfortable. Because it uses warm water and a non-invasive spray, it eliminates the “scraping” sensation of traditional tools. It is virtually pain-free and is an excellent option for patients with sensitive teeth or dental anxiety.

Traditional cleanings often focus on removing hard tartar (calculus) after it has formed. GBT focuses on Biofilm, the invisible bacteria that leads to tartar in the first place.

  • Traditional: Manual scaling and gritty polishing paste.

  • GBT: A “disclosing agent” makes bacteria visible, followed by a gentle air/water stream that cleans areas traditional tools often can’t reach.

This is Step 2 (Disclosure). We apply a harmless, colored agent to your teeth that highlights exactly where biofilm is hiding. This “roadmap” ensures your clinician doesn’t miss a single spot and helps you see areas where you might need to brush a little better at home.

Yes—it’s actually the gold standard for them!

  • For Implants: It cleans around them gently without scratching the metal.

  • For Braces: The Airflow® spray can reach around brackets and wires that are nearly impossible to clean thoroughly with traditional tools.

A GBT session typically takes about the same amount of time as a traditional cleaning. However, because the process is more efficient and thorough, many patients feel the time passes much faster because they are more relaxed.

While GBT is not a chemical whitening treatment, it is highly effective at removing surface stains from coffee, tea, and tobacco. Most patients notice their smile looks significantly brighter and feels smoother immediately after the treatment.

For most patients, a session every 6 months is ideal. However, if you have a history of gum disease, orthodontic appliances, or dental implants, your dentist may recommend a more frequent schedule to keep biofilm under control.
