What Is Zoom Teeth Whitening?

Zoom is a professional in-office teeth whitening system developed by Philips — and one of the most clinically studied whitening treatments available. It uses a hydrogen-peroxide–based gel activated by a specialised LED lamp to break down stain molecules inside the enamel and dentine, lightening the overall colour of your teeth by up to 8 shades in a single appointment.

Unlike over-the-counter strips or trays, Zoom is administered by a dental professional using a significantly higher concentration of whitening agent. The result is dramatically faster and more uniform — and because the treatment is supervised, any sensitivity is managed in real time.

How Zoom Whitening Works — Step by Step

  1. 01

    Preparation

    Your lips and gums are protected with a barrier to ensure only your teeth are exposed to the whitening gel. The whole prep takes about 5 minutes.

  2. 02

    Gel Application

    A professional-grade hydrogen peroxide gel is applied evenly across all visible teeth. This is the active ingredient that breaks apart stain molecules in the enamel.

  3. 03

    Light Activation

    A specialised Zoom LED lamp is positioned over your teeth. The light activates the gel and accelerates the whitening reaction. Most treatments run 3 × 15-minute sessions in the same appointment.

  4. 04

    Rinse & Reveal

    The gel is rinsed away. A fluoride treatment is applied to minimise sensitivity. You leave the chair with a noticeably brighter smile — often up to 8 shades lighter.

Total appointment time: approximately 60–75 minutes including preparation and post-treatment fluoride application.

How Long Do Results Last?

With proper care, Zoom whitening results typically last 12 to 24 months. The biggest factors that affect longevity are diet and lifestyle habits. The most common causes of re-staining are:

  • Coffee and tea
  • Red wine
  • Dark sauces (tomato, soy, curry)
  • Tobacco use
  • Dark berries and juices

Tips to Keep Your Smile Bright

  • Rinse with water immediately after consuming staining foods or drinks
  • Use a straw for coffee, tea, and coloured beverages when possible
  • Brush twice daily with a whitening-formula fluoride toothpaste
  • Schedule professional cleanings every 6 months to remove surface stains
  • Consider annual touch-up whitening to maintain your result

Are You a Good Candidate for Zoom Whitening?

Zoom whitening works best for teeth that are discoloured from extrinsic (surface) staining — the kind caused by food, drink, and tobacco. You are likely a great candidate if:

  • Your teeth are healthy with no active cavities or gum disease
  • Your discolouration is from dietary staining, aging, or tobacco
  • You have not had veneers, crowns, or bonding on your front teeth
  • You are not pregnant or nursing
  • You are 16 years of age or older

Whitening is less effective on intrinsic staining (staining inside the tooth from tetracycline antibiotics, fluorosis, or trauma). If this applies to you, porcelain veneers or composite veneers may deliver better results. Dr. Kadivar will advise you at your consultation.

Frequently Asked Questions

How much does Zoom whitening cost at MiNa?

Our current promotion is $200 for in-office Zoom whitening — that's a full single-visit treatment with professional supervision included. Call us or book online to secure this price.

How long do the results last?

Results typically last 12–24 months, depending on your diet and habits. Coffee, tea, red wine, and tobacco are the most common causes of re-staining. Annual touch-ups (or take-home trays) can extend your results significantly.

Is Zoom whitening painful?

Most patients feel little to no discomfort during treatment. Some experience mild sensitivity in the 24–48 hours following, which resolves quickly. We apply fluoride post-treatment to minimise this.

How many shades whiter will my teeth get?

Clinical studies show Zoom whitening delivers an average improvement of 6–8 shades in a single session. Results vary based on the original shade of your teeth and the nature of the staining.

Can I whiten if I have crowns, veneers, or bonding?

Whitening gel only works on natural tooth enamel — it will not change the colour of restorations like crowns, veneers, or composite bonding. If you have visible restorations, discuss this with Dr. Kadivar at your consultation so we can plan the best approach.

Why is professional whitening better than take-home kits?

Over-the-counter kits use lower-concentration gels (2–10% peroxide vs. 25–35% used in-office) and often cause uneven results or increased sensitivity due to poor tray fit. Professional whitening is supervised, uses higher-grade agents, and delivers consistently predictable results in a single session.
