Many factors can affect tooth color, but why does Teeth turn yellow?
Celebrities and models usually have snow-white teeth, but most people can’t be proud of such a dazzling tone. This is no surprise.
A variety of factors can affect tooth color and can turn yellow, resulting in a shade that people dislike. Causes of tooth yellowing are usually internal or external.
External causes affect the top layer of tooth enamel and can usually be cleaned and corrected. We can vary these, such as nicotine and tar in cigarettes, tannin in wine and tea, and dark-colored foods and beverages.
In principle, any food that leaves stains on clothing can also be left on the teeth. Certain fruits and vegetables, such as grapes, blueberries, cherries, beets and pomegranates, are also capable of this.
These fruits and vegetables contain a lot of chromogens – pigments that get stuck in tooth enamel. Acidic foods can leave stains because they eat away a bit of enamel.
If a person doesn’t take sufficient care of their teeth, we do not clean them with a toothbrush and dental floss, and they do not visit a dental hygienist regularly, tartar can accumulate and the teeth lose their white color.
Internal causes of tooth jaundice are changes in the internal structure of the tooth in the dentin. Such causes are more difficult to eliminate.
Some medications, such as certain antibiotics, antihistamines, prescription mouthwashes, chemotherapy, and radiation therapy, can cause tooth discoloration.
Tooth color also depends on genetics, age, health and injuries. Heredity is also important, so some naturally have lighter, thicker tooth enamel. It is very possible that a person is already born with yellower or whiter teeth than others.
It also depends on the thickness of the enamel, as it is semitransparent. If the enamel layer is thin, we can see a layer of naturally yellow dentin through it. Over the years, the tooth tone can become darker, because over time the enamel becomes thinner.
