At Dental Beauty Welwyn Garden City, we’re proud to offer Guided Biofilm Therapy (GBT) – a cutting-edge dental hygiene treatment designed to elevate your oral care experience.

Experience a gentle clean without the discomfort of traditional tools.
Suitable for children, adults, and patients with sensitive teeth or dental restorations.
Effectively removes harmful bacteria and biofilm, helping to prevent gum disease and tooth decay.
Targets biofilm in hard-to-reach areas for a comprehensive and precise clean.
Guided Biofilm Therapy (GBT) is a modern, minimally invasive approach to dental cleaning that targets and removes biofilm — the layer of bacteria responsible for gum disease, tooth decay, and bad breath. Unlike traditional methods that rely on scraping, GBT uses advanced Airflow® technology to gently clean teeth and gums with a mix of warm water, air, and fine powder.
The treatment begins with a disclosing agent that highlights biofilm, allowing for precise and thorough cleaning. It’s safe for all patients, including those with sensitive teeth, braces, or implants, and leaves your mouth feeling fresher and healthier — all with minimal discomfort.

We begin by applying a disclosing agent to highlight areas of biofilm on your teeth. This helps you see exactly where bacteria are building up and guides our cleaning process.
Using Airflow® technology, we gently remove biofilm and surface stains with a combination of air, warm water, and powder — all without touching your teeth with sharp instruments.
Once your teeth are clean, we examine them thoroughly and apply fluoride if needed to strengthen enamel and protect against decay.
We’ll create a personalised hygiene plan to help you maintain your oral health between visits.
Guided Biofilm Therapy is a modern, gentle way of cleaning your teeth at the dentist. Instead of traditional scraping, it uses a mix of warm water, air, and fine powder to remove bacteria and stains comfortably.

Guided Biofilm Therapy is suitable for almost everyone, including children, adults, and patients with implants, crowns, braces, or dentures.
