Why are teeth discoloured?
Discolouration can be caused by aging, disease, medication,
root fillings, bleeding after accidents or retreating nerves.
The surface of teeth can be additionally stained by beverages
such as coffee, tea, red wine or tobacco consumption.
Your dentist will diagnose the reasons of stains on your
teeth before whitening.

Is whitening always successful?
The whitening process is most successful on slightly
discoloured teeth. Strongly discoloured teeth may take a
longer treatment.

Will whitened teeth remain white?
The whitening effectgenerally is stable for several years.
Should teeth slightly darken again because of food,
beverages or nicotine, the treatment can be repeated every
6 to 12 months.
