Professional teeth whitening in Hilbert
Clinician-supervised whitening using professional-grade materials — with two options designed to suit your schedule. Results vary between individuals depending on starting shade, enamel condition, and lifestyle factors.
Why professional whitening is different
Over-the-counter whitening products — strips, paint-on gels, and pharmacy kits — use lower concentrations of active ingredients than those available in a clinical setting. In Australia, the Therapeutic Goods Administration (TGA) restricts hydrogen peroxide concentrations above 6% to registered dental practitioners only. This regulation, aligned with the EU Cosmetics Regulation, means that the most effective whitening formulations are available only through a dental clinic.
Professional whitening at Sienna Smiles uses clinician-strength formulations applied under controlled conditions. Custom-fitted trays or in-chair protocols ensure even coverage and reduce the risk of soft-tissue irritation. Your dentist assesses your suitability, checks for existing restorations that will not respond to whitening, and recommends the approach that suits your situation. A check-up and clean before whitening removes surface staining and ensures your teeth and gums are in good condition for treatment.
Custom to your teeth
Trays moulded to your dental arch for consistent gel contact and even whitening across all tooth surfaces.
Clinician supervised
Your dentist assesses suitability, monitors progress, and adjusts the treatment if sensitivity arises.
Evidence-based approach
Professional-grade concentrations regulated by the TGA, applied under conditions designed to optimise outcomes.
Two paths to a brighter smile
Both options use professional-grade whitening materials. The difference is how and where you whiten — not the quality of the result. Your dentist will recommend the approach that suits your teeth, your timeline, and your preferences.
In-Chair Whitening
One appointment. Visible results.
A concentrated whitening gel is applied to your teeth and activated under a specialised light. The entire process takes place in a single appointment at the clinic. Most patients notice a visible difference when they leave — though the degree of change varies between individuals.
What's included
- Pre-treatment shade assessment
- Soft-tissue protection and preparation
- Professional-grade hydrogen peroxide gel application
- Light activation (multiple cycles)
- Post-treatment sensitivity management advice
- Review appointment
Patients who prefer a single appointment and want to see a visible change on the same day.

- Dental impressions for custom tray fabrication
- Upper and lower custom-fitted whitening trays
- Professional-grade whitening gel supply
- Detailed usage instructions

Patients who prefer the flexibility of whitening at home on their own schedule.
Book a ConsultationWhat to expect at your appointment
Both whitening options begin with the same assessment. Your dentist will explain the process, confirm suitability, and answer any questions before treatment begins.
Consultation and Shade Assessment
Your dentist examines your teeth, checks for existing restorations, and records your starting shade. Suitability for whitening is confirmed, and the recommended option is discussed.
Preparation
For in-chair whitening, a protective barrier is applied to your gums. For take-home whitening, impressions are taken to fabricate your custom trays — typically ready within a few days.
Whitening Treatment
In-chair: professional-grade gel is applied in multiple cycles over 60 to 90 minutes. Take-home: you apply the gel in your custom trays according to your dentist's instructions, typically 30 to 60 minutes per session.
Review and Aftercare
A follow-up appointment assesses your result and provides guidance on maintaining your shade. Your dentist will discuss dietary factors, sensitivity management, and when a touch-up may be appropriate.
What results look like
The degree of whitening varies between individuals. Factors that affect your outcome include your natural tooth colour, the presence of existing restorations (which do not respond to whitening), enamel thickness, and dietary and lifestyle habits such as coffee, tea, red wine, and tobacco use.
Most patients notice a visible improvement in brightness after professional whitening. However, no whitening treatment can guarantee a specific shade outcome. Your dentist will discuss realistic expectations based on your individual assessment.
Professional whitening is not permanent. Results can last from several months to a few years, depending on your diet, oral hygiene, and lifestyle. Touch-up treatments — particularly with take-home trays — can help maintain your result over time.
Maintaining your result
- Attend regular check-up and clean appointments to remove surface staining
- Rinse with water after consuming staining foods or drinks
- Avoid tobacco products, which cause persistent discolouration
- Use a non-abrasive whitening toothpaste as recommended by your dentist
- Consider periodic touch-up sessions using your custom take-home trays
Individual results vary. The outcome of any whitening treatment depends on your starting shade, enamel condition, existing restorations, and lifestyle factors. Your dentist will discuss realistic expectations at your consultation.
