Tooth whitening


What is tooth whitening?


Tooth whitening is the removal of stains and changing the colour of teeth by using special medication.


The main substance used for whitening is a hydrogen peroxide gel, which is activated by light and releases oxygen on the tooth’s surface to remove stains and discolouration.


Why are my teeth yellow?


There are different reasons for having tooth discoloration. Sometimes teeth are naturally yellowish and some get darker as you age.


The biggest cause of the discoloration of teeth is what your teeth are exposed to. Smoking, dark-coloured drinks, such as wine, black tea or coffee, coloured foods, such as beetroot, cherries and mulberries, and even some medication taken at the early stage of teeth growth, can create dark patches on the teeth.


What happens when I get my teeth whitened?


Tooth whitening is a different procedure than teeth cleaning, which is the mechanical removal of stains, calculus and build-up from the teeth to have healthy gums. In contrast, the whitening process lightens the tooth colour a few shades, the results depending on the original reason for the discoloration.


First you need a complete check-up to make sure your teeth are suitable for tooth whitening and whether there are some contra-indications. This means we make sure you have healthy gums and teeth and if there are any concerns, we fix them before performing whitening.


If there are any fillings or crowns on the front teeth, you need to be aware that they are not going to change colour, so there is a possibility of ending up with a shade difference between your natural teeth and the artificial ones at the end of treatment. In some cases, we may have to renew your fillings and crowns to match the colour of your new naturally white teeth.


There are mainly two techniques to whiten teeth. One way is to have a professional in-office treatment by your dentist. we use Philips ZOOM whitening system to get the best result and normally you can see 2 to 3 shade difference instantly. . Alternatively, you can use an at-home whitening kit. If this is your preferred method, your dentist will provide you with a custom-made tray that fits your teeth and instructs you on how to apply the medication.


Teeth can get some slight sensitivity after a whitening procedure. This is usually temporary and can be relieved by painkillers.


After the treatment you should avoid darkly colored foods. Remember, the better you keep them clean, the longer you can have a whiter and brighter smile.
