They say your smile is your most precious physical feature. This is not an exaggeration. People with attractive smiles look beautiful and feel confident during social interactions. However, with yellow and stained teeth, the situation can be totally opposite. Your yellow teeth can be a cause of embarrassment for you.

What Is Tooth Discolouration and How Does It Happen?

Tooth discolouration is when your teeth colour starts to change. They do not look white or bright anymore. Your teeth may lose their original colour and turn yellow. You can notice dark spots on your teeth which make them look unsightly.

Common Reasons for Stained and Yellow Teeth

There are different reasons for teeth discolouration. Some of them have a direct effect, while some have an indirect impact on your teeth. However, the intensity of these reasons determines the severity of the stain on your teeth.

1. Extrinsic

Your choice of food items and beverages can cause discolouration of your teeth. Tobacco is also considered a vital element that affects the whiteness and brightness of teeth.

2. Intrinsic

In some cases, your overall oral health, medical history and dental issues can cause teeth discolouration.

3. Ageing

Your teeth can lose their brightness with time. Ageing has a profound impact on the whiteness of your teeth.

Factors that Are Responsible for Teeth Discolouration

Before you go to your dentist and book your teeth whitening session, you should be aware of the most common factors responsible for tooth discoloration.

  • Foods and Drinks

Excessive consumption of tea, coffee, wines, cola, marmite and berries can cause tooth staining.

  • Tobacco and Alcohol

Regular and excessive smoking and drinking will definitely change the colour of your teeth.

  • Poor Dental Hygiene

If you do not maintain dental hygiene, your teeth will look stained, dark and yellow. Not brushing or flossing will increase dark or white spots on your teeth.

  • Ailments

When you have ailments that can affect the enamel of your teeth, they start looking darker. Certain infections can also cause dental spots.

  • Treatments

Treatment procedures like chemotherapy or radiation have a deep impact on your teeth colour. Apart from that, some antibiotics are also known to cause tooth darkening.

  • Genetics

Some people are born with naturally brighter and lighter enamel which make their teeth appear whiter than others.

  • Trauma

Though it is a rare cause, in some cases, trauma can be responsible for teeth darkening; especially in children.

Different Types of Tooth Discolouration

1. Brown

Excessive consumption of dark beverages, tobacco and poor oral hygiene are responsible for making your teeth look brown.


Ageing wears down the white enamel layer of our teeth, and the yellow dentine layer becomes more visible.


Chewing betel nuts often turn teeth into black. Apart from that, tooth pulp necrosis can also be responsible for making your teeth appear a few shades darker.


When young teeth come to the direct contact of fluoride, they receive white spots.

Treatment of Tooth Discolouration

There are different ways to prevent tooth discolouration. You can take preventive measures for this. However, if you do not find any satisfactory result after trying them, you should go and meet a certified dentist for the best remedy. They will suggest teeth whitening treatments after examining your oral health.
