Black teeth:
Black teeth can be a symptom of underlying dental disease that shouldn’t be ignored.Teeth normally range in color from white to whitish-yellow and whitish-gray.
Causes of black teeth:
Teeth take on the tone of white due to the amount of calcium present in the enamel.Enamel is the hard, outer covering of the teeth.
Calcium is a naturally white material.
Teeth get most of their coloration from calcium.
However, you can have combinations of other materials in the teeth, which can add shades of gray and yellow.
Your enamel starts to thin over time, causing the underlying layer known as the dentin to show through.
This can make the teeth appear darker.
Tooth enamel can also be stained from the outside.
