Teeth yellow?

Do you want to show white teeth when you smile? Many people spend a lot of effort on whitening their teeth, but you must know that the normal and healthy color of human teeth is not white. Healthy teeth should be light yellow and translucent ivory color. The higher the degree of mineralization of the enamel, the better. The higher the tooth transparency, the more obvious the color of the tooth itself will be.

Teeth may appear yellow due to a variety of factors, including natural aging, dietary habits, and oral hygiene habits. The natural color of teeth can range from off-white to yellowish, depending on individual genetics and enamel thickness. Over time, the enamel (the outer layer of the tooth) may wear away, exposing the underlying dentin, which is naturally yellow in color. This can cause the teeth to appear yellowish, especially as you age. In fact, excessive pursuit of white teeth is not only detrimental to oral health, but also harmful to our teeth and mouth.

What causes yellowing teeth?

1. High degree of mineralization of tooth enamel: The higher the degree of mineralization of tooth enamel, the higher the transparency, the more obvious the color of dentin, and the teeth will easily appear yellow. This condition is very common and completely healthy and requires no special treatment.

2. Exogenous coloring: eating some dyeing foods. For example: if you often drink tea and coffee, but do not brush your teeth in time, the color will settle on the tooth surface; or if you smoke for a long time, the nicotine tar and other substances in tobacco will adhere to the teeth and be difficult to clean.

3. Endogenous staining: During the embryonic period or during tooth development, taking tetracycline drugs destroys the internal structure of the teeth, causing teeth to be stained, and the tooth surface is not smooth enough. The enamel itself is well mineralized, revealing the ivory yellow color of the original inner dentin. In addition, diseases such as caries, dental trauma, and pulp necrosis can also affect the color of teeth.

In addition, parents will find out why the child's new permanent teeth are much yellower than the deciduous teeth during the teething period. Is it cavities? No. Because the enamel of deciduous teeth is not as densely developed as that of permanent teeth, its enamel is not as translucent as that of permanent teeth. During the replacement process of permanent teeth, you will find that the natural tooth color of permanent teeth appears to be a bit yellower. it `s just normal.

What to do if your teeth turn yellow?

Extrinsic staining is primarily caused by factors such as food, drink, tobacco, and poor oral hygiene. In this case, we can use ultrasonic tooth cleaning and sandblasting to remove pigment and plaque from the tooth surface. Ultrasonic tooth cleaning uses high-frequency vibrations to break up dirt and pigment on the tooth surface, and then rinses them away through the scouring action of water. Sandblasting tooth cleaning uses high-pressure airflow to spray special sandblasting powder onto the tooth surface to remove pigment and plaque through friction. Of course, correct brushing method is also an important measure to prevent exogenous staining. When brushing your teeth, you should choose a soft-bristled toothbrush, brush your teeth for no less than two minutes each time, and make sure you brush your teeth with moderate force to avoid excessive wear on your teeth.

Endogenous staining is mainly caused by pigment deposition inside the tooth, pulp necrosis, tetracycline drugs and other factors. For endogenous staining, we can treat tooth bleaching, resin restoration, porcelain veneers, and full crown restoration. Tooth bleaching uses the oxidation of peroxide to break down the pigment inside the teeth, thereby making the teeth whiter. Resin restoration involves applying a layer of resin material similar to the color of the tooth on the tooth surface to cover the pigment on the tooth surface. Porcelain veneers are a restoration method in which thin layers of porcelain are adhered to the tooth surface to improve the color and shape of the teeth. A full crown repair covers the entire tooth with an artificial crown to change the color and shape of the tooth.

Whether the yellowing of teeth is caused by exogenous staining or endogenous staining, we can improve it through scientific treatment methods and correct oral care. Of course, in daily life, we should also pay attention to oral hygiene, conduct regular oral examinations and teeth cleaning, and maintain oral health.
