Teeth Whitening Methods
Step 1: Free Consultation
Prior to all treatments, a consultation is carried out by one of our expert GDC-registered dentists.
During your free consultation, we provide a highly accurate, visual prediction of your likely results — using our Predictive Shade Analysis — before any treatment begins.
Our advanced shade assessment process involves:
- Shade Sampling: We measure the current shade of your teeth and compare it directly to a realistic, predicted post-treatment shade so you can visualise the improvement.
- Surface Activation: Your teeth are thoroughly cleaned with a pre-treatment activator. This removes accumulated micro-debris and prepares
the enamel for treatment.
Step 2: Same Day Treatment
To begin, your dentist personally prepares your mouth using an advanced gum barrier formula to safely protect your soft tissue. Next, a professional-grade whitening gel containing hydrogen peroxide is carefully applied to your teeth.
After positioning a protective mouth guard, a clinically proven Blue Spectrum LED light is distributed evenly across the treatment area, activating the whitening gel to lift stains, while remaining cool and comfortable throughout.
The procedure is performed in two to three 15–20 minute cycles, with your dentist monitoring your comfort and results throughout, completing the entire session within 60 minutes.
Step 3: Instant Results + Aftercare
Following your session, your results are checked, confirmed, and recorded by your dentist, giving you an accurate reference of your new shade. You’ll leave with simple, personalised aftercare advice tailored to your treatment — easy tips for the first 24–48 hours, everyday habits that help your results last, and guidance on maintaining your brightest smile long-term.
For many patients, a brighter smile brings more than a visible change — a randomized clinical trial published in the journal Operative Dentistry found in-office teeth whitening had a positive effect on dental confidence and psychosocial wellbeing, with benefits still present nine months later.
It’s often one of the simplest ways to feel more like yourself, whether that’s speaking up in a meeting, smiling more freely in photos, or simply feeling good every time you catch your reflection.
With expert aftercare built into every visit, all you need to do is enjoy your new smile.
