What is teeth whitening?

A simple, professional way to refresh your smile. Teeth whitening is a cosmetic treatment that lightens the natural shade of your teeth without removing any of the tooth’s surface.

Over time, teeth can pick up stains from foods, drinks like coffee and red wine, smoking, or simply from getting older. Our professional-grade take-home whitening kits offer a safe, effective way to brighten your smile — with guidance from our dental team every step of the way.

How to keep your smile whiter for longer

How to keep your smile whiter for longer

Simple tips for lasting results.

To maintain your newly brightened smile, follow these tips:

  • Brush twice a day and floss daily.
  • Attend regular dental check-ups and hygiene visits.
  • Limit staining foods and drinks (like coffee, tea, red wine, and curry).
  • Avoid smoking, which can quickly discolour teeth.
  • Use a whitening toothpaste occasionally to help maintain your results.

We also offer top-up kits if you’d like to refresh your whitening after some time.

How does take-home teeth whitening work?

Easy steps to a brighter smile.

Here’s how the process works:

  • Consultation: We’ll assess your teeth and ensure whitening is suitable for you.
  • Custom trays: We take precise impressions to create trays that fit snugly and comfortably.
  • Whitening kit: You’ll be given your custom trays and a supply of professional whitening gel.
  • At-home whitening: You apply the gel to your trays and wear them for the recommended time each day — often for a few hours or overnight, depending on the system.
  • Results: Most patients notice a significant improvement in just 10–14 days.

Our team is always on hand if you have any questions or need support during your treatment.
