The Dentalis Spa
Not Just a Clean. A Protocol.
Most clinics talk about "Airflow cleaning." At Dentalis, we go further.
We use the authentic Guided Biofilm Therapy (GBT) protocol — an evidence-based, 8-step system designed by EMS Switzerland to remove plaque (biofilm), stains and bacteria in a way that's precise, comfortable, and safe even for sensitive teeth, implants, and braces.
This isn't just a quick polish. It's preventive dentistry, elevated — where comfort, artistry, and science come together in the heart of Tanjong Pagar.
It is especially helpful for patients who want their visits to be calm, sensory and gentle — not clinical, rushed, or noisy.

Understanding GBT
What Is Guided Biofilm Therapy?
Guided Biofilm Therapy (GBT) is a structured dental hygiene protocol that starts by showing you exactly where bacteria are hiding — and then removes them in a targeted, minimally invasive way.
Instead of scraping every tooth "just in case," we first disclose biofilm with a harmless dye. Once the pink/purple areas appear, your clinician knows exactly where to clean. That's the "guided" part.
GBT was developed to protect teeth and gums, improve comfort, and make professional cleaning more effective over the long term.
GBT removes more than 99% of biofilm when performed correctly — EMS Switzerland clinical data.
The Key Distinction
Airflow Cleaning vs True GBT
Many people in Singapore have heard of Airflow because some clinics use the AirFlow machine to spray powder and water to remove stains. That's good — but it's not the full GBT protocol.
| Feature | Airflow Only | True GBT (Dentalis) |
|---|---|---|
| Steps | 1 step (spray) | 8-step protocol |
| Biofilm disclosure | No | Yes — targeted cleaning |
| Gum pocket cleaning | Surface only | PerioFlow sub-gingival |
| Safe for implants | Limited | Yes — designed for it |
| Protocol standard | No | EMS Switzerland certified |
Put simply: Airflow is a tool. GBT is the full science. At Dentalis, we follow the complete GBT sequence with EMS technology.
The Dentalis Spa Experience
The 8-Step GBT Experience at Dentalis
We've tailored the international Guided Biofilm Therapy protocol to reflect the Dentalis "Art of Care" experience. All of this takes place within our calm, art-led shophouse setting — so the experience feels restorative rather than clinical.
The complete 8-step EMS GBT protocol — as performed at Dentalis Singapore CBD.
-
Assess
Your dentist or hygienist first examines your gums, restorations and risk areas. This makes the treatment personalised rather than routine.
-
Disclose
A harmless dye is applied to your teeth. This stains biofilm so you and your clinician can see where bacteria have accumulated — between teeth, around braces and under the gumline.
-
Motivate
Because you can now see what's often missed at home, we'll guide you on brushing and cleaning more effectively. This makes each GBT visit educational, not just procedural.
-
AirFlow®
Using warm water, air and fine erythritol powder, the EMS AirFlow system gently removes biofilm and light stains from the tooth surface — with no scraping and minimal sound.
-
PerioFlow® if needed
For patients with deeper gum pockets, implants or orthodontic appliances, PerioFlow allows gentle cleaning beneath the gumline without damaging delicate surfaces.
-
Piezon® PS Ultrasonic
Only where necessary, we finish with an ultra-gentle ultrasonic tip to remove any remaining tartar. Because the biofilm is disclosed first, we avoid unnecessary cleaning.
-
Check
Your clinician carefully verifies that all stained areas have been removed. This final check ensures a precise and thorough clean.
-
Protect
A protective or remineralising application may be applied to support long-term enamel and gum health.
Why GBT over Traditional Cleaning
Benefits of Guided Biofilm Therapy
Many clinics advertise "Airflow cleaning," but often only perform the spray step. At Dentalis, we follow the complete Guided Biofilm Therapy protocol, combining science, precision and patient comfort for a more thorough and gentle clean.
Precision
More Precise Cleaning
Because plaque is revealed using a disclosing dye, we clean only where necessary. This improves precision and effectively removes dental biofilm even in hard-to-reach areas.
Aesthetics
Brighter, Cleaner Finish
GBT removes surface stains from coffee, tea and everyday lifestyle habits, restoring your teeth's natural lustre.
Comfort
Gentle, Comfortable Experience
Many patients describe GBT as extremely comfortable — more like a soft jet wash than traditional scraping. Ideal for anyone with dental anxiety.
Safety
Safer for Dental Restorations
The low-abrasion powder makes GBT suitable for cleaning around braces, Invisalign, implants, veneers and other restorations without causing damage.
Gum Health
Better Gum Health
Regular professional cleaning helps prevent gum inflammation and conditions such as gingivitis, periodontitis and peri-implantitis.
Science
Scientifically Supported
Studies show GBT can remove more than 99% of biofilm when performed correctly — EMS Switzerland clinical data. This is the version that actually preserves enamel and protects implants.
Is GBT Right for You?
Who Is GBT Ideal For?
Guided Biofilm Therapy is designed for patients who want effective cleaning with minimal discomfort. It is especially suitable for:
- People with sensitive teeth or receding gums
- Patients with implants, veneers, crowns or bonding
- Patients wearing Invisalign or braces
- Patients with a history of gum concerns who require regular maintenance
- Anyone who prefers a gentler alternative to traditional scaling
Because GBT uses low-abrasion Swiss powder and warm water, it is kinder to enamel and soft tissues than conventional polishing.
Most patients benefit from a GBT session every 3–6 months, depending on their oral hygiene, diet, and risk of gum disease. Your dentist will recommend a personalised schedule.

Frequently Asked Questions
Common Questions About GBT
Everything you need to know about Guided Biofilm Therapy at Dentalis — answered clearly and honestly.
No. Airflow is one component — the spray step. GBT is the full, 8-step protocol developed by EMS Switzerland. At Dentalis, we offer the complete version, including biofilm disclosure, PerioFlow sub-gingival cleaning, ultrasonic finishing and protective application. Many clinics advertise Airflow and mean one step; we follow the full science.
Unlike traditional methods, GBT first discloses exactly where biofilm is hiding — so cleaning is targeted, not blanket. It is minimally invasive, safer for sensitive teeth and gums, reaches hard-to-clean areas more effectively, and polishes teeth gently using fine Swiss powder rather than abrasive paste or metal scrapers.
Yes — that is one of its best uses. The low-abrasion erythritol powder is gentle around restorations, and the PerioFlow handpiece can clean around implants, braces and Invisalign aligners without scratching or causing damage.
Most patients benefit from a session every 3–6 months, depending on their oral hygiene, diet, and risk of gum disease. Patients with implants, a history of gum concerns, or Invisalign may benefit from more frequent sessions. Your dentist will recommend a personalised schedule at your consultation.
Very rarely. Most patients find GBT significantly more comfortable than traditional scaling because there is less scraping, vibration, and abrasion. The warm water and fine powder system is designed to be sensory and gentle, making it a particularly good option for anxious patients or those with sensitivity.
GBT removes surface stains from coffee, tea and everyday lifestyle habits, restoring your teeth's natural lustre — but it is not a whitening treatment. For a visible shade change, we can advise on teeth whitening separately. The Dentalis Ritual+ combines GBT with in-clinic teeth whitening in a single 90–120 minute session.
The Dentalis Spa (GBT + Consultation + OPG X-ray) takes 30–45 minutes. The Dentalis Ritual+ (GBT + In-Clinic Whitening) takes 90–120 minutes. Treatment time varies depending on how much biofilm is present and whether restorations require extra care.
The Dentalis Spa (GBT + Consultation + OPG X-ray) is $259.42 excl GST including GST. The Dentalis Ritual+ (GBT + In-Clinic Teeth Whitening) is $1,131.42 excl GST. Both are performed by our dentist. Prices are valid as of February 2026 and are subject to change.
