Genetics profile can also determine whether your teeth are white or yellow in colour. However it is important to point out that you don’t actually inherit the colour, but rather the thickness of your enamel.

It is important to mention that in rare cases there are also some genetic disorders, which affect teeth development. One of these conditions is called Dentinogenesis Imperfecta (DI) and can be responsible for extremely thin layer of enamel. People who have this condition tend to have weaker than normal teeth, which are in yellow colour.

As a consequence of bad hygiene habits your teeth will be more likely to become yellow in colour.
Certain medications can be also responsible for your teeth being yellow. Both doxycycline and tetracycline might cause this if they are given to children who are younger than eight years old.

Teeth discoloration can be also caused by medications for asthma, high blood pressure and various antipsychotics medications.
