Advanced whitening treatment to brighten your smile and remove stains effectively — safely, and under professional supervision.

Why teeth lose their brightness

Tea, coffee, tobacco, certain medications and simply aging all cause teeth to gradually darken or yellow over time. While whitening toothpaste can lift very light surface stains, deeper discolouration needs a stronger, professionally controlled bleaching agent to shift safely.

Our in-clinic whitening uses a dentist-supervised bleaching gel that lightens the tooth shade several levels in a single sitting, with far more predictable and even results than over-the-counter kits.

Good candidates for whitening

  • Yellow or tea/coffee-stained teeth with healthy enamel
  • No active cavities or untreated gum disease
  • Wanting a brighter smile before a wedding or event
  • Frustrated with results from store-bought whitening strips

Note: Existing crowns, veneers or fillings will not change shade with whitening — we'll advise if this affects your result.

Frequently asked questions

Is professional whitening safe for enamel?

Yes, when performed under dental supervision with a controlled concentration and exposure time — this is far safer than unsupervised home kits.

How long will the results last?

Typically 1–2 years, depending on your diet and habits. Avoiding tobacco and staining drinks extends the results significantly.

Will whitening work on crowns or veneers?

No — whitening only affects natural tooth enamel. If you have visible crowns or veneers, we'll discuss options to keep your smile even.
