What Causes Tooth Staining?
Age: There is a direct correlation between tooth colour and age.
Starting colour: We are all equipped with an inborn tooth colour that ranges from yellow-brownish to greenish-grey, and intensifies over time. Yellow-brown is generally more responsive to whitening than green-grey.
Translucency and thinness: These are also genetic traits that become more pronounced with age.
Eating habits: The habitual consumption of red wine, coffee, tea, cola, carrots, oranges and other deeply-coloured beverages and foods causes considerable staining over the years.
Smoking habits: Nicotine leaves brownish deposits which slowly soak into the tooth structure and cause intrinsic discolouration.
Drugs/chemicals: Tetracycline usage during tooth formation produces dark grey or brown ribbon stains which are very difficult to remove. Excessive consumption of fluoride causes fluorosis and associated ar-eas of white mottling.
