Before we get into the reasons why teeth appear yellow, we must first understand the natural translucency of our enamel. Despite our obsession with whiter teeth, most healthy teeth have a light-yellow hue. Enamel covers the surface of every tooth and has a natural white color., but, the underlying dentin layer is slightly yellowish. This yellowish hue can be seen through the enamel in almost everyone, but it is more noticeable in those individuals who have naturally thinner or more translucent enamel. A plethora of tooth whitening products have hit the market in recent years, each promising a brighter, whiter smile. And, while most people believe that a whiter smile indicates healthier teeth, this is a myth created by advertising companies, not dentists.
The reasons for yellow teeth or tooth discoloration can be mainly classified into three categories.
There are other reasons as well for tooth discoloration, as explained below:
