Teeth Whitening from Aperture Dental Practice in Sunnybank

Tooth whitening/bleaching can either be for:

  1. whitening a whole set of teeth
  2. a single tooth which has discoloured due to the tooth being non-vital. This happens when the tooth has been traumatised, decayed or root-treated (root canal treatment) in the past.

Whitening all your teeth

The two most common ways to whiten your teeth are:

  1. placing the bleach over the teeth and shining a light over the teeth for about an hour – this is done in the clinic with ZOOM! WHITENING, or
  2. making a custom made tray to fit over your teeth and leaving it in for an hour a day for 2-3 weeks

Bleaching Trays


  • Very good result
  • Relatively quicker – only an hour
  • More concentrated bleach is used


  • Sitting still in a dental chair for an hour – can be uncomfortable
  • Higher risk of teeth sensitivity and chemical burn to the gums
  • May still need to have further treatment with bleaching trays
  • More expensive


  • Cheaper
  • Convenient – do it at home!
  • Do it anytime
  • Refill of bleach is cheap


  • A tray in your mouth for 1-2 hours a day for 2-3 weeks
  • Slower results
  • Weaker bleach
  • Results will be noticeable, but gradual

Single tooth/Internal bleaching

When a tooth’s nerve and blood supply is severed (either from trauma or infection), the tooth can potentially start to go darker than the rest of the other teeth. So instead of placing the bleach around the tooth, the bleach can be placed WITHIN the tooth so that it whitens the tooth from the inside out.

When INTERNAL bleaching is decided, the tooth needs to have a root canal treatment done first. Then, the bleaching agent can be sealed within the tooth for several weeks. The bleach can be replenished (about twice) until the desired out come is reached.* At the end of the bleaching stage, the bleaching agent is removed, and a filling is placed to seal the tooth.

*In certain cases, when the desired outcome is not reached, veneers or crowns may need to be considered.


What causes teeth staining?

Discolouration and staining is often caused by food and drinks, such as coffee, red wine, berries, and soy sauce. The outer layer of the tooth, known as the enamel, becomes stained, resulting in yellow or brown marks.

How can I whiten my teeth?

You can get whiter teeth with the use of our new Philips Zoom WhiteSpeed system. In fact, it's possible to get your teeth up to eight shades whiter with just one hour-long treatment. The treatment is an in-office procedure, and comes in different types and strengths, so you can choose the one that best suits your sensitivity, lifestyle and expectations.

How does the Philips Zoom WhiteSpeed system work?

The Philips Zoom WhiteSpeed lamp is an in-office system, which comprises a lamp with a variable intensity setting. This means that the treatment can be customised for each individual patient. The system also includes special desensitisers, which help to minimise sensitivity and protect your enamel during the treatment. The treatment will be supervised by your dentist.  

Before beginning treatment, you will need to come in for a consultation, at which time your teeth will be assessed to ensure that you are a suitable candidate for Zoom Whitening.
