Teeth Whitening

Teeh Whitening (also known as bleaching) is a dental process used to lighten the shade of teeth that have not improved with professional cleaning. The general teeth whitening process involves the application of a bleaching agent onto the surfaces of the front of your teeth. The active bleaching agent most commonly used in teeth whitening formulas is hydrogen peroxide. Depending on the whitening system recommended by your dentist, the whitening strength of the bleaching agent used may vary.


At Healthy Smile Dental, we currently provide two teeth whitening options.

First, we have the “take-home kit” whitening option.

A set of custom-made trays are created for you to take home, along with a bleaching agent gel and applicator kit. At home, you will need to apply the bleaching agent into your custom trays and wear them for a specified period of time. At HSD, we provide a whitening system called Pola Day. This system has proven to be very effective treatment option for our patients. Typically, this process requires you to wear the tray(s) for an one hour daily over 7 to 10 day period. The main drawback of this whitening method is that you need to be responsible for wearing the trays for the recommended time consistently during the treatment period.

The second option is the “in-chair” bleaching provided by our dentists.

This whitening treatment is provided during a visit to our dental clinic, and usually last about two hours. For in-chair bleaching, your dentist does all the work for you by applying the bleaching agent directly onto your teeth, and using a cool blue light to activate the bleaching process rapidly. In-chair teeth whitening provide the best results instantly, without the patient having to prepare and wear a whitening tray day after day over an extended period.


At Healthy Smile Dental, we use “Zoom” whitening system.

Both systems work effectively, but with minor differences in the treatment process and strength.

The advantages of whitening/bleaching:

  • Whitening is suitable for undamaged natural teeth that require a lighter shade. (Crowns, veneers or facings do not respond to whitening).
  • Custom-made trays can be reused at a later date.
  • Upper and lower teeth can be treated simultaneously.
  • Approved tooth whitening products are biosafe.

The disadvantages of whitening/bleaching:

  • Not all natural teeth respond well to whitening. For example, yellow, orange and brown coloured stains usually respond well to whitening. However, grey coloured stains may only lighten a little, so the results may not be what you expect.
  • Individual teeth may respond to bleach differently.
  • White composite restorations are not affected by the whitening process, and may need to be replaced to match the whitened teeth in order to achieve a consistent shade in your smile.
  • When a bleaching agent comes into contact with your gums for a prolonged period, you may experience irritation and burning.
  • Bleaching should be performed in a controlled setting. Some over-the-counter whitening products can be too powerful and can damage teeth if used incorrectly over an extended period. We do not recommend nor endorse over-the-counter whitening treatments for this reason.
  • Bleaching may not be suitable if you have a pre-existing sensitivity to bleaching, cracked/worn teeth, receding gums or gum disease (periodontitis).

It is important to consult with your dentist so that you can make an informed decision about which teeth whitening option is the most suitable for your teeth. If you are considering teeth whitening, give our friendly team a call to book a consultation.
