The most usual case of acquired discolorations is the darkening of the teeth with advancing age. Consumption of stain-causing beverages (coffees, teas, colas etc.), tobacco use; traumas to the teeth, old dentures, laminate veneers and fillings could also lead to discoloration. Use of antibiotics (such as tetracycline) during tooth development or extensive fluor intake may cause tooth discoloration as well.

What Is Tooth Whitening And How Ýs Ýt Carried Out ?
Tooth whitening is a procedure to lighten teeth and remove stains and discolorations occurring within the structure
(enamel-dentine layers) of the teeth. At present there are two different methods of tooth whitening:
The first method, which is self-practicable, involves the following steps: * Your dentist will take an impression of your teeth and have a thin rubber mould prepared, that you will put around your teeth. * The patient puts the whitening product into the special mould and applies it onto the teeth to be whitened for at least 6 to 8 hours daily (preferentially during sleep). * Termination of the treatment in 1 to 2 weeks on the average.
The second method is carried out in a dentist’s office and involves the following: * The whitening substance is applied to the teeth by an experienced dentist * A laser or UV light is shone onto the relevant teeth for a certain time to enhance the action of the agent. * The whitening effect is seen immediately at the end of the procedure. Although at-home procedures are more effective, the choice will depend on factors such as the extent of discoloration, desired time-span of the treatment and dentist’s opinion.
