Teeth Whitening

Teeth Whitening is fast becoming the No.1 requested and performed cosmetic dental procedure in Australia.

In everyday life, the microscopic pores of our teeth are stained with coffee, tea, red wine, smoking. These in conjunction with age can make your teeth stained and unattractive. Teeth whitening, also known as teeth bleaching, lightens teeth and helps to remove stains and discolouration

How Does Teeth Whitening Work?

Teeth whitening is most effective on surface stains caused by age and coloured food and drinks.

Teeth bleaching technique uses peroxide to lighten teeth, which occurs due to breakdown of the peroxide gel providing highly active oxygen free radicals. These effectively break up the unattractive pigmented molecules causing the stains to be removed.

Is Tooth Whitening for Everybody?

The lighter the stain, the easier it is to whiten. Significant whitening can be achieved in many cases, but there is no way to predict how light your teeth will get. More severe discolouration like tetracycline staining or fluorosis may not whiten as well and may require subsequent veneers.

Also, a point to note, existing tooth- coloured fillings or crowns will not alter in shade.

Are There Any Requirements Prior To Whitening?

Before we start any whitening procedures, we need to ensure you have a healthy mouth. If you have poor gum health (gingivitis or periodontitis) or if you have cavities, these need to be treated first.

It is highly recommended that you have a check-up and clean prior to whitening

How White Will the Teeth Get?

Everyone’s teeth respond differently; Clinical studies have shown that teeth can get up to eight shades lighter, maybe even higher.

The general dental consensus is the shade of the teeth should match the whiteness of a person’s eyes.

How Long Will It Last?

Immediate whitening results can be quite dramatic due to minor dehydration of the teeth. It is normal for the colour to tone down after treatment when your teeth rehydrate to a natural white tone.

After a period of time, the teeth may regress in shade. This is natural and depends on the lifestyle and diet. To maintain teeth at their optimal whiteness, it is advised to avoid staining food, drinks and smoking.

Touch-up treatments may be required every 6-12 months to retain the initial whitening achieved.

Teeth Whitening Procedure

At white cross dental, we offer teeth whitening procedure in two clinically proven and safe systems: At- home whitening and In-House whitening.

Home Teeth Whitening

On your initial visit, our dentist will take impressions/moulds to make custom trays that fit your mouth. Once made, the trays will be checked for a good fit and specific instructions are given on how to carry out the procedure. The tray is loaded with the peroxide gel and worn between 2 and 4 hours for at least 2 weeks. Generally, the higher the concentration of the peroxide, the shorter the time per day you wear the trays.

In-House Teeth Whitening

This system is perfect for those who want instant results. Your teeth can be lightened by up to 8 shades in less than an hour. We also offer a take- home kit to top- up the initial whitening achieved.

  • We first protect your gums and surrounding tissues with a barrier membrane, and a ‘before’ picture is taken.
  • The whitening agent is applied to your teeth and a blue light is shined on it to activate the peroxide.
  • This whitening agent is replaced several times during the procedure to give optimal results.

Once the treatment is completed an ‘after ‘picture is taken, so you can appreciate the full effects of the whitening procedure.

Potential Side Effects of Teeth Whitening

The majority of our patients undergo teeth whitening without any adverse effects. Complications that can occur are infrequent and usually minor in nature.

Tooth sensitivity

In the first 24 hours after whitening, some people may experience tooth sensitivity. This is usually mild, unless your teeth are normally sensitive. A mild analgesic will usually be effective in eliminating any discomfort; a desensitising toothpaste can also help.

Gum and soft tissue irritation

Whitening may cause temporary inflammation of you gums, lips or cheek margins. This is usually the result of the gel coming in contact with the tissues. This is a minor problem and will subside with a few days.

Rinsing with warm salt water can relieve it. It may be necessary to reduce the time you are wearing the trays or stop using it for a short time until it resolves.

Defective Fillings and Cavities

If these are present, the gel may leak into the cavities, between the defective fillings and tooth, which may cause some discomfort. If this happens, the nerve of the tooth can be damaged.
