Teeth whitening is a cosmetic dentistry procedure performed on natural teeth. Active oxidising agent penetrates the porosities of enemal and breaks down stain deposits.Continious consumption of tea, coffee, red wine or smoking stain teeth. Other than external coloration, usage of tetracycline type antibiotics during childhood, excessive Fluor intake and enamel defects discolor teeth. Additionally traumatised necrotic teeth change in darker colors.
For an effective bleaching, clean plaque free tooth surface is a must.
Bleaching trays are given to patients. Bleach is applied into those trays as described. Patient wears the tray for recommended time according to the concentration (2-4 hours).Patient must brush his teeth before and after the application and avoid consumption of coloring products during treatment.Disadvantage of home bleaching is the long term (about 1 month) needed for whitening, while the advantage is its being more affordable.
High concentrated bleach is applied by the dentist at clinic. Gum is covered with a protective layer. Sessions are 45 minutes long and the number is decided upon severeness of coloring.Quick result and furter whitening (when home method is inadequate) are this method's advantages.

Opposite to other methods this brightens teeth from the inside out.Dentist controlled whitening is not harmful for the teeth. Enamel does not wear off, instead, coloring molecules are removed through enamel. Sensitivity in following days are normal and temporary.Maintenance of light shade achieved depends on patient's care.Bleaching does not change color of composite fillings or porcelain.
