What are the causes of yellow teeth?

There are many reasons for the appearance of yellow teeth. The main reason is nothing more than smoking, drinking tea, drinking coffee and other pigmented teeth. Yellow teeth can also cause various oral diseases, which can pose a serious threat to health if not treated in time.
Causes of Yellow Teeth Food In our daily diet, we inevitably eat colored foods. In addition to light-colored foods such as tofu and eggs, most of the other colorful and colorful foods are the causes of yellow teeth.
There are many kinds of bacteria on the tooth surface, they secrete many sticky substances on the tooth surface. Tobacco (smoking or chewing tobacco), drinking tea, drinking coffee, cola, red wine, and colored foods leave pigments on our teeth. These pigments attach to these sticky substances, gradually turning the tooth surface yellow or black.
Over time, these substances will gradually penetrate into the teeth from the surface of the teeth, form internal stains, and slowly discolor the inside of the teeth. This kind of teeth is called exogenous stained teeth. In other words, as long as the teeth have “intimate contact” with color in life, they have the possibility of being dyed and turned yellow! Drugs and water quality When teeth are developing, especially children under 8 years old, taking tetracycline drugs can easily cause tooth discoloration to tetracycline teeth. In some areas, especially in some mountainous areas, due to the high fluoride content in the water, drinking too much fluoride will make the teeth yellow, and it is not 1~2 teeth, but a mouthful of rhubarb teeth, which becomes dental fluorosis. These stained teeth are called endogenously stained teeth. These “sick” teeth, with dark pigments buried deep in the teeth, cannot be touched by daily brushing. Only through special whitening methods can the teeth be “reborn”. Hygiene Habits Some people do not pay attention to oral hygiene, and do not have the habit of brushing their teeth correctly in the morning and evening, so that a layer of food residue, soft scale, calculus, cigarette stains, tea stains and other “bad things” accumulate on the surface of the teeth. These yellow teeth are not caused by the yellowing of the teeth themselves, but by poor oral hygiene. Age-related yellow teeth we can never resist, that is, natural aging. As we grow older, our teeth are hard to withstand the vicissitudes of life, and the color gradually fades and turns yellow. Age can wrinkle the skin, just as it can make the teeth less white.
