What is the colour of teeth?

The colour of teeth can vary from person to person, but the most common shade is a light yellow or ivory. The colour of teeth is determined by a number of factors, including the thickness and mineralisation of the enamel, as well as the underlying dentin. The enamel is the hard, outer layer of the teeth, and it is composed of a mineral called hydroxyapatite. The dentin is the underlying layer of the teeth, and it is made up of a softer mineral called collagen. The thickness and mineralisation of the enamel can affect the colour of the teeth, with thicker and more mineralised enamel appearing whiter. The colour of the dentin can also affect the colour of the teeth, with darker dentin appearing more yellow or brown. In addition, the colour of teeth can be affected by external factors such as diet, smoking, and medications.
