Why do our teeth turn yellow?
Because our teeth need some color in their lives.
Our teeth basically consist of three parts.
The outermost part is enamel.
Enamel is white in color.
Beneath the enamel, there is dentine.
It is yellow in color.
Then comes the part called pulp, which has
blood vessels and nerves.

Is this the same pulp found in our fruit juices?
Please concentrate.
When we drink or eat acidic fruits and beverages like lemon, orange juice, soft drinks, etc.,
They erode or wear away the enamel exposing the yellow dentine and thus, making teeth appear yellow.
However, did you know that some people's teeth are naturally yellowish?
This is because in such people, the layer of enamel is thin causing the yellow color of the dentine to appear more clearly.
Thus, making their teeth appear naturally yellow.
