Teeth Whitening

 Fast, Effective Brighter Smile

Our teeth work as a mirror, reflecting our diet, lifestyle and even health, the colour of our teeth is influenced by these factors that might lead to tooth discolouration, which gives an unpleasant smile.

Millions and millions of people choose to whiten their teeth to get rid of these unpleasant non-attractive discolourations and get a whiter smile.

 How do my teeth have the colour and how do they change?

We should know and understand that the teeth are divided into 3 layers the enamel which is the outer layer of the tooth which is translucent and white in colour.  Dentine the thickest layer of the tooth present between the first and last layer and is yellowish in colour and the pulp layer which contains the nerves and blood supply. The colour we see is due to the reflection and scattering of lay rays from both the enamel and dentin layers. 

The colour of the teeth depends on the thickness of enamel and dentin in which a thinner enamel layer will allow more appearance of dentin giving a more yellowish colour to your teeth. Also, enamel contains small tiny pores which will hold up stains gained from diet or other habits.

 So now we got the science behind tooth colouring out of the way; what is tooth discolouration?

Tooth discolouration is one of the most challenging and common cosmetic problems affecting most people, especially those seeking the perfect smile to boost their confidence and give them that Hollywood Smile they always dreamed of.

The causes of discolouration may be from stains covering the outer layer of teeth or may be due to stains in the inner layers of teeth.

So there are two kinds of stains:

  • Extrinsic stain: the stain which occurs on the outside layer of the tooth, caused mainly by food and beverages, such as coffee, tea, soda, cola and even smoking. 
  • Intrinsic stain: It is the discolouration of the tooth structure from the inside, which mainly occurs due to abnormalities or systemic diseases that occur during the development of the permanent tooth leading into this kind of stain.

For extrinsic stains, teeth whitening is the best way to give you a brighter, nice-looking smile. But for the intrinsic stains, it requires other cosmetic approaches such as porcelain veneers or Lumineers®.

So teeth whitening is making your teeth brighter, but how does it do that and what are the kinds of teeth whitening?

You should know that there are two kinds of teeth whitening:

  • Vital teeth whitening: when the teeth pulp and nerves are still present.
  • Non-Vital teeth whitening: when the teeth pulp has already been removed.

For vital teeth whitening they are also divided into two types:

  • professional whitening teeth
  • Home teeth whitening

The main concept behind every kind of teeth whitening is placing bleaching (whitening material) on the teeth surface. The material will chemically break down creating oxygen particles which penetrate the enamel layer and brighten your teeth.teeth_whiting2

What are the differences between each kind of teeth whitening?

1.) Vital teeth whitening is also divided into two types :

       > Professional teeth whitening.

       > Home teeth whitening.

Professional teeth whitening

It is done usually using hydrogen peroxide as the bleaching material which will then be activated using a light activation system. We use the best activation system combined with the best whitening material to assure you a white, bright smile. Our whitening procedure will take up to an hour.

Home teeth whitening

After taking an impression and fabricating a custom tray our dentist will provide you with a special bleaching material that is weaker than the materials used in the in-office teeth whitening. You will apply the material to the tray and will place it in his mouth for a couple of hours. You will continue this process until the desired result is achieved. 

Non-vital teeth whitening

The vital teeth whitening may not have an effect on teeth which are discoloured and is root canal treated. Our dentist will provide bleaching to these teeth by placing the bleaching material inside the tooth leaving it for a couple of weeks until the desired result is achieved.
