Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible.

At the edges of teeth where there is no dentin underlying the enamel, the color sometimes has a slightly blue or translucent off-white tone, easily observable on the upper incisors. Since enamel is semitranslucent , the color of dentin and any material underneath the enamel strongly affects the appearance of a tooth.
The enamel layer is whiter and semitransparent, and contributes blue, pink green tints to the tooth color. [6] The underlying dentin layer is darker than enamel, yellow-brown in color, and less transparent.
