Guided Biofilm Therapy (GBT)

A Gentle, Modern Approach to a Healthier Smile

At Pearl Dental, our hygiene appointments are designed to do more than just clean your teeth, they help protect your long-term oral health.

We are proud to offer Guided Biofilm Therapy (GBT), an advanced and minimally invasive hygiene treatment that removes plaque, stains and harmful bacteria in a much gentler and more comfortable way.

Whether you want to improve your gum health, maintain fresh breath, remove staining, or simply enjoy a more comfortable hygiene experience, our team is here to help.

What is Guided Biofilm Therapy (GBT)?

GBT is a modern hygiene treatment that focuses on the gentle removal of biofilm, which is the soft plaque bacteria that builds up on the teeth and gums and can lead to gum disease, tooth decay and bad breath.

Using advanced Airflow technology, warm water and a fine powder, GBT removes plaque and surface stains with far less discomfort than traditional cleaning methods. Any remaining hardened deposits can then be removed carefully and precisely.

This means a more comfortable, more personalised, and more effective clean.

What to Expect at Your Hygiene Appointment

  1. Plaque Disclosure

We apply a special dye to highlight areas of biofilm on the teeth. This helps us identify exactly where treatment is needed and allows you to see the areas that need more attention at home.

  1. Gentle Airflow Cleaning

Using warm water, air and a fine powder, we gently remove plaque, biofilm and surface staining from the teeth.

  1. Precision Removal of Remaining Deposits

If there is any tartar or calculus left behind, this is removed carefully using gentle ultrasonic technology.

Frequently Asked Questions

What is Guided Biofilm Therapy (GBT)?

Guided Biofilm Therapy (GBT) is a modern, comfortable, and highly effective method of professional teeth cleaning. It uses advanced technology to gently remove plaque, biofilm, and stains from your teeth and gums, helping to prevent gum disease, tooth decay, and bad breath.

Biofilm is a soft, sticky layer of bacteria that naturally forms on teeth and gums. If left untreated, it can lead to cavities, gum disease, and other oral health problems.

GBT uses a special disclosing solution to highlight plaque and biofilm before removal. This allows your hygienist to clean your teeth more thoroughly while being gentler on your teeth and gums than traditional methods.

All of our patients find GBT very comfortable. The treatment is minimally invasive and often preferred by patients who have sensitive teeth or gums.

A standard hygiene appointment usually takes around 30 minutes. More extensive treatments may require a longer appointment depending on your oral health needs.

Your dentist or hygienist will advise which appointment is most suitable for your needs.

An extensive hygiene appointment is recommended for patients with heavier plaque and tartar build-up, gum disease, staining, or those who have not had a hygiene visit for a longer period of time. Additional time allows for a more thorough clean and personalised oral health advice.

GBT is excellent at removing many external stains caused by food, drinks, and smoking, helping to restore a brighter and cleaner smile.

Most patients benefit from seeing the hygienist every 6 months. However, some patients with gum disease, dental implants, or other oral health concerns may be advised to attend more frequently.

Yes. GBT is safe and highly effective for patients with dental implants, orthodontic appliances, crowns, veneers, and other dental restorations.

GBT removes surface stains and leaves your teeth looking cleaner and brighter. However, it does not change the natural colour of your teeth like professional teeth whitening treatments.
