Tooth Whitening


Tooth whitening has become one of the most popular ways to enhance your smile. It provides a safe and proven way to lighten the shade of your teeth.


At Queensway Dental Clinic, we aim to offer you a full range of whitening treatments, tailored to meet your individual requirements. We provide a number of treatments, including home/tray based tooth whitening and internal tooth whitening. This allows you – based on the recommendation from our dental professionals – to make an informed decision.


What is tooth whitening?

Whitening is a procedure where tooth discolouration is ‘whitened’ to a lighter shade through chemical means. It is a safe procedure when carried out under professional dental supervision. The General Dental Council (GDC) has identified that tooth whitening is part of the practice of dentistry, and dentistry must only be carried out by dental professionals who are registered with them.


Treatment time and results usually depend on the severity of the discolouration. Both vital (i.e. live) and non-vital teeth (i.e. teeth with root fillings) can be bleached and may take several visits to complete. It is not effective on dental restorations such as amalgam fillings, metal or porcelain crowns, veneers etc. However, we can advise on the options for replacing restorations after whitening to complete your smile make over.

What causes tooth discolouration?

Eating habits: The consumption of red wine, coffee, tea, cola, carrots, oranges and other deeply-coloured beverages and foods causes considerable staining over the years. In addition, acidic foods such as citrus fruits and vinegar contribute to enamel erosion. As a result, the surface becomes more transparent and more of the yellow-coloured dentine shows through.

Smoking habits: Nicotine leaves brownish deposits which slowly soak into the tooth structure and cause intrinsic discolouration.

Drugs/chemicals: Tetracycline usage during tooth formation produces dark grey or brown ribbon stains which are very difficult to remove. Excessive consumption of fluoride causes fluorosis and associated areas of white mottling. This type of discolouration is difficult, but not impossible to treat. It may take months or anything up to a year to achieve results with a supervised home bleaching regime.

Trauma: Falls and other injuries can produce sizeable cracks in the teeth, which collect large amounts of stains and debris.

Age: There is a direct correlation between tooth colour and age. Over the years, teeth darken as a result of wear and tear and stain accumulation. Teenagers can achieve immediate, dramatic results from whitening. In the twenties, as the teeth begin to show a yellow cast, teeth-whitening may require a little more effort. By the forties, the yellow gives way to brown and more maintenance may be called for. By the fifties, the teeth have absorbed a host of stubborn stains which can prove difficult (but not impossible) to remove.

Starting colour: We are all equipped with an inborn tooth colour that ranges from yellow-brownish to greenish-grey, and intensifies over time. Yellow-brown is generally more responsive to bleaching than green-grey.

Grinding: Most frequently caused by stress, teeth grinding (gnashing, bruxing, etc.) can add to micro-cracking in the teeth and can cause the biting edges to darken.
