In a nutshell, the thickness of your enamel and the level to which it is stained determines the color your teeth will have. Genetics, in most instances, play a major role in determining the quality, color, and type of enamel one gets. Thin enamel can be translucent hence can reveal the yellow inner parts of the tooth. A thicker enamel, however, has an opaque layer making the enamel seem brighter and whiter. Lifestyle choices too have an impact on the color of one’s teeth. Apart from genetics, some other causes of yellow (stained teeth) include;
- Using tetracycline before age 10
- Drinks such as coffee and wine
- Poor dental hygiene
- Aging
- Tooth trauma
