The natural whiteness of our teeth can diminish or change over time, leading to yellow hues or stains. Here are some insights to understand why this happens.
The primary factors for teeth discoloration are often related to our consumption. The food and beverages we take in can cause a gradual yellowing. Below are the two most common reasons.
Enamel Erosion
Enamel, the tooth’s outermost white layer, acts as a protective shield. Beneath the enamel lies a layer called dentin, which is naturally darker. As the enamel thins, whether due to acidic foods, the progression of certain gum diseases, or simply aging, the dentin begins to show through, giving teeth a yellowish color. Furthermore, the density of enamel can vary naturally from one person to another.
Dietary Influences
Drinks like tea and coffee as well as certain colored foods can leave behind stains on teeth. These substances don’t just stain but can also contribute to enamel erosion. Yellowing can be exacerbated by smoking, the use of tobacco products, or taking certain medications.
