AirFlow and Guided Biofilm Therapy (GBT) — types of professional teeth cleaning compared

Key facts

• AirFlow is an air-polishing method for plaque and stains
• GBT is a structured protocol built around air-polishing
• Hard tartar still needs ultrasonic or hand scaling
• Examination decides the cleaning, not the brand name
• Ask the clinic about availability of air-polishing

The main types of professional cleaning

Professional cleaning generally combines several techniques. Ultrasonic scaling uses a vibrating tip and water spray to break up hardened tartar, both above and just below the gum line. Hand scaling with fine instruments removes remaining deposits and smooths root surfaces. Polishing with a rubber cup and paste removes surface stains. Air-polishing, of which AirFlow is a well-known brand, uses a controlled jet of air, water and very fine powder to remove soft plaque, biofilm and stains, including around braces, implants and in tight spaces. Deep cleaning for gum disease, or root planing, treats deeper pockets, usually under local anaesthetic.

What Guided Biofilm Therapy involves

Guided Biofilm Therapy is a step-by-step cleaning protocol developed around air-polishing. A typical sequence starts with an assessment of the gums and the application of a disclosing solution that stains plaque so it can be seen clearly. Visible biofilm is then removed with air-polishing above and slightly below the gum, and any remaining hard tartar is removed with a slim ultrasonic tip. The final check confirms that all stained plaque has gone, and the patient receives home-care advice. The idea is to clean thoroughly while minimising contact with the tooth surface and avoiding unnecessary abrasive polishing.

Air-polishing versus ultrasonic scaling

These methods are complementary rather than competing. Air-polishing is very effective at removing soft plaque and stains and is often described as comfortable, particularly around sensitive areas, implants and orthodontic brackets. However, it does not remove heavy, hard tartar on its own; ultrasonic and hand scaling remain necessary for calculus. Conventional polishing with a paste works well for stains on smooth surfaces. For people with gum disease, the key factor is thorough removal of deposits from deeper pockets, which depends on technique and examination more than on the device. Air-polishing powders also need care in some medical conditions and on certain restorations.

Choosing the right cleaning for you

The most suitable cleaning depends on your gums, the amount of tartar, staining, sensitivity and whether you have implants, braces or restorations. Rather than choosing a method by name, ask the dentist what the examination shows: whether there is gingivitis or deeper gum disease, how much tartar is present and how often you should be cleaned. At Manhal Medical Center, Dr. Fariba Alnoory performs professional scaling and polishing and deep cleaning when needed. If you are specifically interested in air-polishing or a GBT-style protocol, ask the clinic about current availability, and she will explain whether it would add benefit in your case.

Aftercare and keeping biofilm under control

Whatever cleaning method is used, plaque begins to re-form within hours, so home care decides how long the results last. Brush twice daily with fluoride toothpaste, clean between your teeth with floss or interdental brushes, and consider using disclosing tablets at home occasionally to see areas you miss. Patients with implants, bridges or braces need extra attention around them. Mild gum tenderness after a thorough clean is common and settles within a day or two. Contact the clinic if bleeding is heavy, if pain increases or if you notice swelling, as these may indicate an underlying gum problem that needs review.

Professional cleaning removes hardened tartar that brushing can't, polishes away surface stains, and lets the dentist spot gum disease early.
