The normal color of teeth is light-yellow.
Understanding Tooth Color
While many people desire bright white teeth, a light-yellow hue is actually the most common and natural color for healthy teeth. This color comes from the dentin, the layer beneath the enamel.
The Role of Dentin
- Dentin's Natural Color: Dentin is the layer of tiny tubules under the enamel that connects to the dental nerve. This layer is naturally yellow.
- Enamel Translucency: The outer layer of enamel is translucent, meaning that the yellow color of the dentin shows through, resulting in the light-yellow appearance of teeth.
- Indication of Strength: A light-yellow tint actually indicates that your teeth are strong and healthy.
Why Are Some Teeth Whiter?
It's important to note that teeth can vary in color due to several factors, including:
- Enamel Thickness: Thicker enamel can make teeth appear whiter.
- Diet and Habits: What you eat and drink, as well as habits like smoking, can affect the color of your teeth.
- Age: Enamel thins with age, causing the underlying dentin to become more visible and the teeth to appear darker or more yellow.

While whiter teeth may be aesthetically appealing, a light-yellow hue is a normal and healthy color for teeth. It is primarily influenced by the natural color of the dentin layer.
