Teeth Whitening ( Bleaching )

Permanent teeth whitening process is a solution applied to lighten teeth several tons for the ones which have changed color and yellowed for various reasons. It is process of discolouration occurred on the structure of the tooth (enamel and dentin).

For a beautiful smile, healthy and white teeth are important. However, staining can be caused by structural changes occurring during the formation of the teeth, using some antibiotics while being a child or in mother's womb, foods and drinks, and the amount of fluoride in drinking water. Besides, aging, old dentures, fillings and coatings are also effective in the disappearance of whiteness of teeth.

Since all of organic and inorganic stuff in tea, coffee we drink, all drinks with colorant such as cherry juice, red wine, pomegranate juice and cigarette are accumulated in the porous enamel structure on the surface of the tooth, our teeth get darkenedwith over years.

Instead of making porcelain coating, etc. on darkened or yellowed teeth, permanent teeth whitening method is applied which is also referred as bleaching and at the end of this process, teeth are lightened up to eight to ten tones depending on the teeth condition.


There are different methods to whiten teeth. The first one is whitening with the help of a professional dentist (Office bleaching), and the other one is home bleaching which is applied at home in accordance with the advice of your doctor.


Clinical professional whitening with the help of a dentist is applied as follows:

Bleaching medication is placed on the tooth by a dentist who has experience of this process.

Laser light is maintained onto the respective tooth for a certain time.

Laser light does not whiten the tooth. It just starts the necessary chemical reactions by ensuring to activate the whitening gel (the laser does not penetrate into the tooth).

This process takes less than 1 hour and although it gives an instant result, multiple sessions may be needed for desired whiteness level.

The result is observed as soon as the process ends.


The dentist takes measures of the patient's mouth and prepares thin rubber molds which will be fixed on teeth.

The patient wears the mold on the teeth to be bleached at least 6-8 hours a day by placing the medicine into the special molds which are prepared for himself (preferably while sleeping).

This treatment takes approximately 1-4 weeks.

Although both methods are effective, preference depends on coloration degree, how quickly the treatment is desired to be terminated and the opinion of the dentist.
