What is teeth whitening?

Teeth whitening gently lightens the natural colour of your teeth — brightening stains from coffee, tea, red wine, smoking, or simply the years. Professional whitening uses carefully formulated gels that break down stains within the enamel, revealing a noticeably whiter smile. Our take-home system is prescribed by your dentist and worn with custom-fitted trays designed specifically for you.

Why choose teeth whitening?

Teeth whitening is one of the most popular cosmetic dental treatments because it makes a visible difference with minimal treatment time.

  • A brighter, more confident smile — Visible improvement after a short course of treatment — tailored to your goal.

  • Safe and dentist-prescribed — Professional-grade gels, supervised by a clinician — not an off-the-shelf kit.

  • Custom-fitted trays — Made precisely for your teeth, so the gel sits comfortably and whitens evenly.

  • Gradual, natural-looking results — Whitening at your own pace means a controlled, even brightness — not over-bleached.

  • Convenient at-home treatment — Wear the trays at home for the recommended time each day. No studio visits mid-course.

We use Boutique Whitening

  • 3

    At-home whitening treatment — You’ll receive your professional whitening kit and clear instructions. Wear the trays for the recommended time each day over a short period.

  • 4

    Reveal your brighter smile — Your teeth become gradually whiter and brighter — a natural, refreshed smile to feel confident about.

Frequently asked questions about Teeth Whitening

How long does teeth whitening last?

Professional whitening results typically last 1–3 years, depending on your diet and habits. Avoiding heavily staining foods and drinks (coffee, red wine, tea, smoking) keeps your smile brighter for longer. A top-up course every year or so maintains the result.

Is teeth whitening safe?

Yes — when prescribed and supervised by a dentist. Professional whitening gels are formulated to be safe for enamel when used correctly. We only whiten teeth that are healthy, and we check in with you throughout treatment.

Will whitening cause sensitivity?

Some patients experience mild temporary sensitivity during treatment — this is normal and usually resolves within a few days of finishing. We use low-sensitivity formulations and can pace your treatment to minimise discomfort if you know your teeth are sensitive.

Can whitening damage my teeth?

Professional whitening doesn’t damage enamel when used as prescribed. The gel works by breaking down stains within the enamel, not by stripping it. Over-the-counter or unsupervised whitening can be riskier — which is why we only recommend dentist-supervised treatment.
