This procedure is used to lighten the colour of natural teeth. The colour of teeth varies among individuals and in different age groups. Teeth can naturally darken over time and colour is influenced by a person's genetic makeup, as well as by any surface stains or deposits in or on the teeth.
If teeth are dark due to external stains or deposits, they will need to be cleaned prior to tooth whitening. All of our whitening treatments are clinically approved and range from our easy to use home bleaching kits to our state-of-the art in house tooth whitening treatment, which takes about one to two hours to complete.
We offer 2 different procedures, dependent on your individual requirements, and we will be more than happy to discuss these treatments at your consultation appointment.
Suitability for tooth whitening
Whilst many are able to undergo a tooth whitening procedure, there are some people who are not suitable candidates. Suitability for treatment is determined through information you provide on a tooth whitening questionnaire and information gathered during your consultation and screening.
Should your dentist advise you are not a suitable candidate for this procedure, you may be able to explore other treatment options to achieve the smile you want.
The great advantage of tooth whitening is that it does not involve the destruction of existing healthy tooth structure, which can result in tooth death and the necessity of root canal therapy.
Types of tooth whitening
A gel, normally carbamide or hydrogen peroxide, is used to whiten teeth. Chlorine Dioxide whitening products are never used in this practice as they strip the surface off the teeth, making the teeth much more prone to further staining.
We offer 2 different tooth whitening procedures:
- Tray System: Impressions are taken of your teeth to make a flexible whitening tray (similar to a very thin gum shield) and this fits over and around your teeth. The gel is placed in the tray and used in accordance with the advice given by your dentist.
The teeth will become gradually lighter over time. A course of treatment takes a variable number of weeks and results may differ depending on the initial darkness of the teeth, the concentration of the gel used and the frequency of application.
- Power Whitening: You attend an appointment where your gums are isolated using special materials. A gel is placed directly onto your teeth and a special high intensity light is focused on the teeth for 15 minutes. This is then repeated up to three further times (all in the same appointment) and takes between 90 minutes and two hours.
How much whiter will my teeth look?
This varies from individual to individual, and also depends on the type of whitening system used. Some people respond very well to teeth whitening and have dramatically whiter teeth as a result, whereas others may notice very little difference at all. People with heavily stained yellow teeth tend to have more dramatic results than those with slightly discoloured teeth. Your dentist will be able to advise you on the likely results
following a consultation.
How long does the lighter appearance last?
Teeth that have been whitened have a tendency to eventually return to their original colour. The time this takes depends on a patient's diet and whether they smoke. The
colour obtained would be expected to be maintained for between 18 months to two years, but patients who regularly eat darker foods and smoke will darken their teeth more quickly.
