Teeth Whitening

Whitening works by lightening the middle layer, also known as dentine, of our teeth. The hard outer coating of our teeth has microscopic pores that absorb stains. Teeth whitening agents, usually carbamide peroxide or hydrogen peroxide, penetrate the teeth to remove stains that have embedded there.

Why does the tooth whitening result vary for different people?

Teeth stained due to smoking, food and drink respond well to professional teeth whitening. When stains are due to medication, fluorosis or other conditions, we will provide a full evaluation to find the best teeth whitening option for you.

Our Take-Home Teeth Whitening Method

A custom mouthpiece, or ‘tray,’ is made to fit your teeth by Dr Zhang. This tray fits over your teeth and in order to hold the bleaching material against your teeth for a specified period.

Different concentrations of bleach are then worn via the tray from as little as half an hour a day for an average of 10-14 days.

The treatment is determined by our dental team and may differ for each patient.

If the teeth become more sensitive to hot and cold, a desensitising agent, like Tooth Mousse®, may be used in the same tray.

Results with this method are usually excellent.

How long will my teeth stay white?

Teeth will develop stains over time due to red wine, coffee, tea and smoking. You can retain your custom whitening trays to touch-up your smile whenever new stains develop.

Most discolouration can be removed by bleaching, which is a very conservative, safe and non-invasive approach to creating a brighter, more appealing smile.

We recommend arranging an evaluation with one of our Alderley dentists to find out if your teeth are healthy enough for teeth whitening. There are some stains such as tetracycline and fluorosis that are difficult to bleach, so other options, such as veneers or crowns may be more suitable for your situation.

Since teeth whitening only works on natural tooth enamel, opting to whiten your teeth before having fillings, crowns or veneers for brighter results.

Is tooth whitening safe?

Research indicates that tooth whitening shows no changes to the surface of the teeth when a bleaching solution is used. Therefore, there is no damage to the tooth whatsoever.

Is laser or light bleaching better?

We have found our take-home teeth whitening method to be the safest and most effective way to lighten your teeth. By eliminating the need for a light, we can reduce sensitivity, damage to the tooth and gum, and also any false positive whitening results.

Laser whitening is different again to light-activated whitening and is not as common. Most dentists that claim to do laser whitening are not actually using a laser, but the light machine. With very few exceptions, such as grey or blue teeth tones, you will achieve ideal results using our take-home teeth whitening system without the added expense and sensitivity of lights.

Are there any disadvantages to dental tooth whitening?

Call Alderley Dental to find out whether your teeth are suitable for dental teeth whitening. Dental tooth whitening is not a permanent whitening method, and the result can vary among patients. 

Some patients also experience some discomfort due to the sensitivity of their teeth throughout the whitening process. This can vary, and there are usually things we can do to minimise the discomfort of this feeling. We will discuss this with you at your whitening appointment.
