Causes of tooth discolouration - those pesky brown and yellow stains! Part 2

From Part 1 of this blog we know that:

Endogenous stains occur while teeth are developing, before they even come through your gums as a child;

Exogenous stains occur after your teeth have developed and are through your gums;

Extrinsic stains occur on the outer layer of your teeth, the enamel. These tend to look like yellow or brown spots on the surface of your teeth; and

Intrinsic stains are located underneath your tooth enamel in the dentin layer.

Now that we have done a quick recap, lets look at some more causes of tooth discolouration -

Berries Whether they’re blueberries, raspberries, strawberries, mulberries or blackberries, all berries can stain your teeth.

Tomato based foods - Pizza, Pasta, Salsa and Soup Tomato based foods not only stain your teeth but they are highly acidic, they can eat away at your precious enamel allowing stains to go further into your teeth.

Soy Sauces Dark colour can cause stains on your teeth, whether its mixed into a stir-fry or put it straight onto your sushi.

Balsamic Vinegars Richness and dark colour make it a common stain producer. Like all vinegars, balsamic vinegar is highly acidic and another one that eats away at enamel.

Artificial Food Colouring - Highly Pigmented Dyes Most lollies, ice blocks and sweets contain artificial food colouring. The high sugar content of these foods feed bacteria in your mouth which can lead to holes in your teeth and darkened spots.

Acidic Fruits and Vegetables - Tomatoes, Oranges, Pineapples, Lemons etc These can all cause enamel erosion, in turn discolouring teeth.

Tea and Coffee These rich dark coloured drinks contain 'tannins', an organic substance that can build up on the surface of tooth enamel causing stains.

Wine Most people know that red wines  with their dark colour  will discolour teeth, but it is also the acidity level that causes stains and weakens enamel. Interesting fact, white wines are more acidic than reds.

Sports Drinks and Soft Drinks Just like your lollies and sweets, these too contain highly pigmented dyes and have high sugar contents that stain teeth and contribute to tooth decay. The chemicals added in these drinks usually make them highly acidic - even the lighter coloured ones. Once again your precious enamel is at risk of erosion.

Tobacco A common cause of stains on teeth. The nicotine found in tobacco products, such as cigarettes, chewing tobacco, pipe tobacco and cigars causes yellow and brown stains that worsen the longer you use them.
