Thooth whitening has become one of the most frequently requested dental procedures by the public.
The public has come to demand whiter more perfect smiles and in response many choices for tooth whitening have been made avaible. Tooth whitening is any process that lightens the color of the tooth. Bleaching is defined here as the chemical degradation of the chromogens. The active ingredient in most whitening products is hydrogen peroxid which is delivered as hydrogen peroxide or carbamide peroxide.
Quicker teeth lightener can be achieved through in-office whitening because the products delive higher concetration of peroxide. Consequently gingival tissues are usually protected before the agent is applied. Some products claim to increase the oxidation of chromogens by exposure to heat or intense blue light. Teeth lightening results are seen after one 30 to 60 minutes.
HOW LONG WİLL THE TREATMENT LAST?
İt is dificult to predict the persistence of bleaching because the patient may routinely expose their dentition to food or beverages which are known to stain teeth and would experience restaining in a few months. However if the teeth are not exposed to chromogens such as coffe,red wine,cigarette smoke it would be resonable to assume that whitened teeth could persist up to 2 years.
