|Colour of teeth|
Since the enamel of permanent teeth is slightly transparent, the yellowish colour of the underlying dentine is shown through it. Therefore, permanent teeth will appear slightly yellowish. As we get older, the dentine increasingly grows thicker, and it is normal that our teeth become more yellowish.
The enamel of deciduous teeth is not as transparent as our permanent teeth. That is why deciduous teeth look milky white.
