It is important to brush your teeth after waking up in the morning and before sleeping at night. This is an important practice for oral hygiene. This keeps the bacteria in the mouth under control and prevents bad odor. But the shine of teeth may appear dull despite brushing. The reason for this is your eating habits

Why don’t white teeth always stay white? Shining teeth are a sign of good health, but their shine does not depend only on superficial cleaning. Teeth are made of many layers, so its color depends on the condition of the layers. The outermost layer is enamel, which is white and slightly transparent. Beneath this is dentin which is light yellow in colour. When the enamel becomes thin or stained, the yellow dentin underneath becomes visible. Therefore, teeth may appear yellow even after cleaning.

effect of diet
One of the main reasons for stains on teeth is our diet. Dark-colored foods and beverages can stain the enamel over time. This includes tea, coffee, cola and soft drinks, red wine. These contain coloring agents which stick to the enamel. If not cleaned on time, they accumulate and form stains. Along with this, lack of essential nutrients can also weaken the enamel.

yellow teeth from citrus fruits
Citrus fruits, soda, processed foods and sour things increase acid in the mouth. This acid slowly wears away the enamel. When the enamel thins, the yellow dentin underneath becomes more visible. Therefore, even after regular brushing, teeth may appear yellow.

effect of age also
Age is also the reason for yellowing of teeth. The enamel naturally thins with age. It wears away due to years of chewing, brushing and exposure to acids. Due to this, the yellow dentin below becomes more visible. This is a normal process.

when to see a doctor
If teeth suddenly become excessively yellow, deteriorate quickly, or there is pain and sensitivity, a dentist should be examined. Keep in mind that it is important to brush daily, but it is not necessary that the teeth always remain completely white.
