Why is GBT a game changer?

Dental BioFilm is the main aetiologic factor for dental decay, gum disease (periodontitis) and peri-implant infections. Periodontitis can increase the risk of systemic diseases, such as cardiovascular and respiratory disease, arthritis or diabetes.

Regular oral hygiene, combined with professional measures such as Guided Biofilm Therapy keeps biofilm under control – for a better oral and systemic health.

GBT follows the European Federation of Periodontology (EFP) recommendations on Professional Mechanical Plaque Removal (PMPR) and Oral Hygiene Instructions (OHI) for Home Care of the European Federation of Periodontology (EFP).

“Periodontal Health — for a better life!”

Frequently Asked Questions

What is the cost of Guided Biofilm Therapy?

Our GBT fee is generally £99 per session. However, the actual cost of GBT varies depending on your specific needs. It’s recommended to inquire with our staff first for specific pricing details.

How does GBT differ from traditional teeth cleaning methods?

GBT differs from traditional cleaning by emphasising the guided removal of biofilm, using state-of-the-art technology like air-polishing devices and specially formulated disclosing agents. This precision ensures comprehensive plaque removal and enhanced oral hygiene.

Is Guided Biofilm Therapy suitable for all patients?

GBT is generally suitable for most patients, offering a versatile and adaptable approach. However, individual assessments are necessary to determine the specific needs and suitability for each patient.

What are the key components of GBT?

The key components of GBT include a thorough assessment, disclosing agents to identify biofilm, ultrasonic or hand instrumentation, and air-polishing devices for efficient biofilm removal.

Does GBT involve the use of lasers or other advanced technologies?

GBT primarily utilises air-polishing devices and ultrasonic instruments, rather than lasers. These tools offer precision and effectiveness in biofilm removal without the need for invasive technologies.

Is GBT a painful procedure?

GBT is generally a comfortable procedure. The technology used minimises discomfort, and the process is well-tolerated by most patients.

How long does a typical GBT session take?

The duration of a GBT session varies but typically takes around 45 to 60 minutes. However, this can depend on individual oral health conditions and the extent of cleaning required.

How often should GBT be performed for optimal results?

The frequency of GBT depends on individual oral health needs. For many patients, it is recommended every 6 to 12 months to maintain optimal oral hygiene.

Can GBT be used for patients with braces or other orthodontic appliances?

Yes, GBT is suitable for patients with braces or orthodontic appliances, offering effective biofilm removal in challenging areas.

Is GBT suitable for individuals with sensitive teeth or gums?

GBT is generally suitable for individuals with sensitive teeth or gums. The technology used allows for a gentle yet thorough cleaning process.

Are there any age restrictions for GBT?

GBT is suitable for individuals of all ages. It can be adapted to meet the specific needs of both children and adults, contributing to a lifetime of good oral health.

Does GBT replace regular dental check-ups?

No, GBT does not replace regular dental check-ups. It complements routine dental visits by providing a comprehensive cleaning and biofilm removal, but regular check-ups are essential for overall oral health monitoring.

Can GBT treat periodontal disease?

GBT can be part of the treatment plan for periodontal disease by effectively removing biofilm. However, the overall management of periodontal disease may involve additional interventions based on the severity of the condition.

What are the benefits of GBT over traditional scaling and polishing?

GBT offers benefits over traditional methods by providing more efficient biofilm removal, less discomfort, and improved precision, resulting in enhanced oral health and a brighter smile.

Can GBT be used for cosmetic teeth cleaning?

Yes, GBT can contribute to cosmetic teeth cleaning by removing stains and biofilm, resulting in a cleaner and more aesthetically pleasing smile.

Are there any side effects associated with GBT?

GBT is generally safe, with minimal side effects. Some patients may experience mild sensitivity or temporary gum irritation, but these effects are usually short-lived.

How long do the results of GBT last?

The results of GBT can last for an extended period, but maintaining regular dental check-ups and proper oral hygiene practices will help sustain the benefits over time.

My fear of dentists is gone, thanks the team at Essential Dental Care. So caring, so considerate, so professional. I had a hygienist service and two fillings. I have never had such wonderful experience sitting in a dentist chair. I was recommend this place by a friend, and I am forever grateful. There is a group of us now, who all go here :) Thank you all and you sure have me as your regular customer for years to come.

My husband and I would not go anywhere else, Dr Paul is the most experienced dentist that we have had and explains everything to you. My husband is in the middle of getting implants and he was a bit apprehensive at first but Paul was very patient and explained everything that is going happen and reassured him. It is a long process but will be worth the wait. Also the staff could not be more helpful and very friendly too. Would recommend this practice to anyone.💓

由於家母牙齒出問題,規勸良久才肯就醫,幾經波折,在愛丁堡找到這家可以全程以廣東話溝通的牙科診所,診所職員 Carman了解後,認為情況緊急,特意安排了快期,隔天便能就診。牙醫 Paul 診症細心,並教導了日常的護理方法及開药,回家後一兩天病情已告好轉,值得推薦。

First thing to say is that Paul does very high quality work. He pays attention to detail, spots trouble before it happens, and is very quick to find an appointment time if you do have pain, and sorts it out effectively every time. Secondly, he is very gentle; he’ll tell you when he’s about to numb you up, but to be honest, that’s about the last you’re aware of it. He checks with you that you’re ok, and is careful to make sure your mouth isn’t open wide any longer than it needs to be. Thirdly, he and Michelle run a very effective and friendly practice; they made every effort to keep open as much as possible during lockdown whilst giving every confidence that they were doing all they could to keep their patients safe. And they still do. I can’t commend them highly enough nor thank them warmly enough for all their care and attention.

Cannot fault the team at Essential dental. They are always seem to run on time and put me at ease throughout. Dr Au just gets on with it. Would recommend to anyone.

I have had an extremely positive experience at Essential Dental Care. While a bit pricey (as with any private dentist), Dr Paul has always been very patient and happy to answer any questions I've had about my treatment. I also have to say that this is the first dental practice I asked about a partial denture who did not immediately try to upsell me to a dental implant. While I do need to eventually get the implant, it can be very costly and Dr Paul understood that I really just needed a cosmetic solution in the interim. Highly recommended.
