  • Professionally supervised — safe for your enamel
  • Gum protection to minimise sensitivity

Why Professional

Whitening that actually works.

Store-bought strips and toothpastes only reach surface stains, unevenly and slowly. Professional whitening uses stronger, dentist-supervised gel that lifts deeper discolouration for brighter, more even results.

Because it's done under supervision with your gums protected, you get faster whitening with far less of the sensitivity that comes from guessing at home.

Two Ways to Whiten

Choose what suits you.

Both use professional-grade gel — the difference is speed versus convenience. Many patients combine the two for the brightest, longest-lasting result.

In-office whitening

Fastest — one visit

Professional gel applied in the chair for dramatic, same-day brightening. Perfect before a wedding, event, or photos.

Custom take-home kit

Convenient — whiten at home

Custom-fitted trays and professional gel you use over about 1–2 weeks, at your own pace — and FREE for new patients who complete a full new-patient exam (not available with CDCP).

Is It Right for You?

Great for everyday stains.

Whitening works best on natural teeth with healthy enamel. You're likely a great candidate if your teeth have dulled from any of these.

Coffee, tea & wine

The everyday drinks that gradually dull and yellow your smile.

Natural ageing

Teeth naturally darken over the years as enamel thins.

Tobacco stains

Stubborn discolouration that brushing alone won't shift.

A big occasion

A wedding, reunion, or photos — and you want to look your best.

What to Expect

Simple, and comfortable.

An in-office visit is usually completed in a single appointment — and you'll walk out several shades brighter.

  • Keep up your cleaningsRegular professional cleanings remove the surface stains that dull your shine.

Questions

Frequently asked.

No — professional whitening is safe for your enamel when it's supervised, which is exactly why we protect your gums and use dentist-grade gel rather than guesswork at home.

Results vary from person to person, but most patients brighten noticeably — by several shades. We'll note your starting shade and set realistic expectations at your visit.

Whitening isn't painful. Some people feel mild, temporary sensitivity during or just after — because it's professionally supervised with your gums protected, we keep that to a minimum, and it usually fades within a day.

Whitening only lightens natural teeth — it won't change the colour of crowns, veneers, or fillings. If you have dental work in your smile zone, we'll let you know what to expect and plan around it.

Anywhere from several months up to a couple of years, depending on your diet and habits. A quick touch-up with a take-home kit keeps your smile bright between visits.

In-office is fastest, with dramatic same-day results — ideal before an event. Take-home is convenient and gradual. Many patients do an in-office boost, then maintain it with a take-home kit.

Whitening is a cosmetic treatment and usually isn't covered by insurance — we'll give you the exact cost up front. New patients: your take-home kit is free after completing a full new-patient exam (not available with CDCP).
