Causes of Yellowing Teeth
Due to high dental plaque
Dental plaque is a sticky layer caused by bacteria and leftover food that accumulates on the teeth when not properly cleaned. Over time, dental plaque combines with minerals (calcium, fluoride, etc.) in saliva to form tartar and becomes very hard.
Consuming sugary and dark-colored foods
Chemical colorants added to or the natural colors of food will stick to the tooth enamel, causing the tooth surface to turn yellow. In addition, foods that are high in sugar, such as cakes, ice cream, and chocolate, will accumulate bacteria that cause plaque.
Frequent consumption of tea and coffee
Similar to dark-colored foods, the habit of consuming dark-colored, acidic or sugary drinks can have a negative impact on dental health, causing teeth to become yellow and affecting tooth enamel.
Foods high in sugar, such as cakes, ice cream, and chocolate, will accumulate bacteria that cause plaque.
Years of smoking
Tobacco contains nicotine, which causes yellowing and forms brown/black stains between teeth. In addition, the habit of smoking also damages the lungs, reduces blood flow to the gums, and causes inflammation.
Inadequate oral hygiene
Inadequate oral care and hygiene habits can cause plaque to accumulate on the surface of the teeth, causing them to become yellow and even cavities.
Due to tooth enamel
Yellowing teeth can be caused by thin tooth enamel, exposing the yellowish dentin. People with tooth fractures or chips that expose the dentin can also lead to darker yellow teeth.
Other causes such as teeth grinding during sleep can also exert strong pressure on the teeth, causing them to crack or wear down the enamel, gradually causing yellowing of the teeth.
Teeth Whitening

When using baking soda for teeth whitening at home, it is important to do it correctly. Depending on the condition of your teeth, it is best to consult a dentist.
– Using dry baking soda: Apply a small amount of baking soda evenly on the tooth surface. After about 1 minute, rinse your mouth thoroughly with water.
