The natural color of teeth is determined by the density of tooth enamel, the quality of dental tissue (dentin) and the microrelief of the teeth.
These factors, in turn, depend on genetics. In addition, the color of teeth can be affected by health conditions or external influences.
Even if a person has a naturally snow-white smile, but, for example, he works in a hazardous industry, smokes or often drinks strong tea or coffee, his teeth may turn yellow over time.
On the contrary, if a person's tooth enamel is not very white to begin with, but he leads a healthy lifestyle, he can maintain a beautiful smile.
Factors affecting tooth color:
• consumption of coloring foods and drinks;
• smoking;
• contact with non-ferrous metals (e.g. iron or nickel) and volatile substances (e.g. bromine, iodine);
• pulp proliferation;
• depulpation or death of the nerve;
• changes that occur with age;
• diseases affecting the liver and bile ducts;
• use of certain medications;
• injuries.
Due to the above-mentioned effects, teeth can acquire not only yellow, but also other shades, such as green, gray, blue, pink, and can even turn black.
