Bleaching Teeth

What is bleaching teeth?

Bleaching teeth is a method for making teeth whiter, a kind of deep cleaning of the enamel. The basis of the formula is a chemical oxygen bond with the discolouring molecules that get left behind in the enamel over time. Bleaching your teeth gives them back their natural colour. And yes, you can also bleach your teeth at home, you do not have to go to the dentist.

Discoloured teeth, how does it happen?

Just as with the colour of your skin, the colour of your hair or the whites of your eyes, the colour of your teeth is genetically determined. Teeth are made out of enamel, dentin and pulp. The colour of your teeth primarily depends on the colour and thickness of the dentin. This is different for everybody and it explains why some people have whiter teeth than others. Enamel on the other hand is practically transparent. Canine teeth are by their nature somewhat more yellow than the other teeth because the dentin layer is thicker. Bleaching by yourself or at the dentist can be a first step in making your teeth more beautiful.

Extrinsic discolouring 

This type of discoloration is the result of pigment molecules that get left behind on the enamel of the tooth and can generally be dealt with by a whitening treatment. Yes, in the event of extrinsic discolouring you can bleach your teeth yourself.


Coffee, tea, red wine, cigarettes, etc, are not friendly to our teeth. They make our teeth more yellow and darker. Depending on the extent to which certain foodstuffs are consumed, the discolouring can be darker in one person than in another. Bleaching your teeth yourself ( at home or in the car during rush hour) can provide a solution to this.


Extrinsic discolouring can also increase with age. This is a result of wear, the necks of teeth that become exposed or more fragile enamel such that small cracks occur through which pigments can easily penetrate the porous dentin. As a result of ageing the layer of dentin also becomes thicker such that the teeth and molars often become darker. There is no age limit to bleaching your teeth yourself.

Intrinsic discolouring

Intrinsic discolouring - in contrast to extrinsic – is inside the tooth structure. Two known examples of this are tetracycline discolouring and fluorosis. In this case there is no point in bleaching your teeth at home or at the dentist.


This discolouring occurs during the formation of the teeth and is, as it were, built into the dentin. The result is generally a grey - sometimes orange - discolouring, over the whole tooth or otherwise. Bleaching makes little or no sense here.


Fluorosis occurs when children are given too much fluorine while their teeth are forming. This creates chalky, white spots in the enamel of the permanent (adult) teeth. In this case bleaching the teeth is of little or no use.



These two intrinsic discolorations are generally difficult to remedy with a whitening treatment. In these cases treatment with veneers (facets or facing) is advisable instead of bleaching your teeth yourself. Consult our Smile Consultants.

Don’t be fooled

You can never bleach your teeth “whiter” than their original colour. People who claim that their teeth, because they bleach their teeth at home or at the dentist, seem whiter than ever before are deceiving themselves.
