Yellowing of teeth is a problem that many people encounter in their daily lives, and it not only affects aesthetics, but may also hide hidden health risks.So, what exactly causes the yellowing of teeth?In fact, a variety of factors are involved behind this, including living habits, eating habits, oral hygiene and ageing.

　　First, the influence of living habits

　　The colour of teeth is closely related to our living habits.Long-term smoking or betel nut chewing habits will lead to the deposition of large amounts of tobacco stains and betel nut residue on the surface of the teeth, which are not only difficult to remove, but will also make the teeth gradually turn yellow or even black.In addition, regular consumption of drinks containing pigment, such as coffee, tea, cola, etc., will also make the surface of the teeth stained, accelerating the process of yellowing teeth.

　　Second, the "brand" of eating habits

　　Our eating habits also invisibly leave a "mark" on the teeth.Regular consumption of high-sugar foods, such as candy, desserts, etc., is not only easy to cause dental caries, but also may make the surface of the teeth become rough, more likely to adsorb pigment, which leads to yellowing of the teeth.At the same time, acidic foods and beverages will also corrode the enamel on the surface of the teeth, so that the teeth become fragile and easily coloured.

　　Third, oral hygiene "negligence"

　　Oral hygiene is the key to keeping teeth white.If daily brushing is not thorough, or do not develop the habit of regular cleaning, food debris and plaque will accumulate on the surface of the teeth, forming difficult to remove tartar (calculus), so that the teeth gradually become yellow.In addition, incorrect brushing may also damage the enamel on the surface of the teeth, making it easier to stain the teeth.

　　Fourth, the "traces" of ageing

　　As we age, our teeth will gradually change.With age, the enamel will gradually wear thin, revealing the inner layer of dentin, and the colour of dentin itself is more yellowish.Therefore, even if your teeth are white when you are young, you may have yellowing teeth in old age.

　　Fifth, how to fight against yellowing teeth?

　　Improve lifestyle habits: Try to quit smoking and limit alcohol, and reduce the intake of betel nut and other harmful substances.At the same time, reduce the intake of beverages and food containing colouring, or rinse your mouth in time to clean your mouth after drinking.

　　Adjust dietary habits: Control the intake of high-sugar foods and eat more fibre-rich foods and fresh fruits and vegetables to help keep your mouth clean and teeth healthy.

　　Enhance oral hygiene: insist on brushing your teeth every morning and evening, using the correct brushing method and a suitable toothbrush.Meanwhile, go to the dental hospital regularly for scaling and oral examination to remove tartar and plaque in time.

　　Use whitening products: Among the many teeth whitening products on the market, Mecondi stands out with its professional toothpaste and tooth powder products, which are popular among consumers.These products are not only convenient and fast, but also effective, which makes them one of the best choices to improve the problem of yellowing teeth.

　　To sum up, yellowing of teeth is not an overnight result, but the result of a combination of factors.By improving lifestyle habits, adjusting diet, enhancing oral hygiene, and using whitening products, we can effectively combat yellowing of the teeth and achieve a brighter, more confident smile.
