Major causes of Yellow Teeth

Try to restrict the amount of these drinks you consume, and if you do, make sure to rinse your mouth out thoroughly with water.

Brush your teeth twice daily as well.

Sugary and Starchy Foods

Along with beverages, some foods, such as apples, potatoes, pasta, berries, tomatoes, etc., can stick to the teeth and leave behind stains that can turn the teeth yellow, brown, green, or orange.

Even salads with vinegar dressing have the potential to leave stains.

Reduce your intake of these foods or other extremely acidic foods and beverages to prevent it and protect your enamel.


One more cause of yellow teeth is ageing because as people age, their teeth’s enamel thins out from normal wear and tear, exposing the dentin’s natural yellow colour.

This can happen more quickly if the teeth suffer trauma as cause by fall, blow or shock.


The majority of people are aware that smoking is detrimental to their health, it is equally harmful to your dental health too.

Dr Sayona Swati Das says :

“Smoking, pan masala, tobacco, etc. include nicotine and tar that leave teeth with stains that are difficult to remove and can cause yellow teeth.”

They can also lead to gum diseases and mouth cancers in some cases.

Quit consuming all these harmful substances for the sake of your dental health.


Diseases that damage the enamel and dentin, including jaundice, are a less known cause of yellow teeth.
