Are there any Side Effects?
There are side effects associated with whitening but, over the last 20 – 30 years, they have been proven to be transient
and fully reversible, depending on what whitening system is being used. It should be noted that the whitening
materials have been in use for more than 50 years. The side effects are usually some mild sensitivity to cold and also
some gum soreness. Approximately 60-70 per cent of patients have very mild side effects that are easily managed.
Will the Colour Fade?
The colour change is usually not permanent. On average, there is a some colour rebound in the first 2 weeks, then a
slow regression of colour over 2-3 years. This is why the at home system is essential, to balance this rebound and to
reduce the regression of the colour. The good news, however, is that to maintain the colour costs approximately $40
every 6 – 12 months if only the at home gels are used for maintenance. This is a very easy and successful way of
maintaining the colour. As with any cosmetic procedure, appropriate maintenance is necessary.
Will the Structure of the Teeth be Affected?
The materials do affect the structure of the teeth slightly. Many studies have likened the effects of the whitening
materials to drinking a can of soft drink, which is rapidly reversed by the body’s natural repair systems (saliva).
What About My Existing Fillings?
Unfortunately, filling materials and materials used in crown and bridgework will not change colour. It is therefore
necessary that teeth whitening be carried out prior to any other cosmetic treatment in order to achieve the best possible
overall look of the teeth for years to come. However, teeth whitening tends to brighten the teeth as well so the oldcrown and bridgework colour tends to blend through better after whitening
