The natural colour of teeth
The natural colour of teeth is determined by several biological factors and varies from one person to another. Enamel, the protective outer layer of the teeth, is translucent and allows some of the dentine beneath it to show through. The thickness and quality of the enamel play a major role in how white teeth appear. The thicker the enamel, the more light it reflects, creating a whiter appearance. Conversely, thinner enamel allows more of the dentine to show through. Dentine is a naturally yellowish substance that makes up most of the tooth.
