The dentists from shanghai dental tell that the cause of endogenous yellow
teeth is that the pigment is not on the surface but in the tooth tissues.
Endogenous yellow teeth are mainly dental fluorosis and tetracycline teeth. If
since the childhood the person lives in the area where drinking water contains
much fluoride, it is easy for him to get dental fluorosis. And his teeth will
present tan plaques which look ugly and disgusting. So we should strictly
control the content of fluoride in drinking water in the daily life. On the
other hand, tetracycline teeth are caused by taking tetracycline drugs before
the age of eight. If tetracycline drugs the mother take are absorbed by the
fetus during pregnancy, the child may get dental fluorosis. Tetracycline
molecules can combine with the calcium in the tooth tissues and form a kind of
stable complex compound. This kind of complex compound will deposit on the teeth
and make teeth yellow and brown.
We have to admit that we will never be able to resist the natural aging.
Years wrinkle the skin and also make teeth no longer bright or white. In the
process of development, teeth will be very easy to turn yellow and crispy
without adequate nutrition. So it is important to pay more attention to
protecting teeth when we are young. We all know that calcium deficiency can
affect the teeth whitening. With the loss of calcium, the teeth stiffness will
reduce greatly. The pigment will accumulate more easily. As a result, the yellow
teeth appear. Usually the doctor suggests that you take calcium and vitamin D
regularly.
Next let’s talk about the causes of exogenous yellow teeth. Teeth will be
yellow when people smoke for a long time or drink carbonated beverage in a long
term. People can stop smoking and refuse the carbonated beverage. But in our
daily life, we are inevitable to eat food with different kinds of colors. In
fact, apart from tofu, eggs and other food of light colors, most of the
delicious food is colorful, which cause the yellow teeth. There are a lot of
bacteria on the surface of teeth and they secrete many sticky substances.
Tobacco, tea, coffee, cola, wine, and the other colorful food bring about
pigment for teeth. The pigment adheres to the sticky substances and gradually
makes the teeth yellow. If we do not clean teeth promptly and properly, the
pigment will accumulate over a long period. And if the internal teeth become
yellow or black, it will be more difficult to whiten them. It is no exaggeration
to say that the teeth may be yellow as long as they contact the colorful
food.
Actually, cleaning your teeth patiently can prevent yellow teeth. But some
people don't care about oral hygiene. They have no good habits of brushing teeth
in the morning and evening. Therefore, food residue, soft dirt, tartar and smoke
stains accumulate on their teeth quickly.
Since you know the factors that contribute to your yellow teeth, you can be
more targeted to protect or whitening your teeth.
Tips:Stay fresh. To check the freshness of your breath, lick your palm and smell
it while it's still wet. If you smell something, it’s time for a sugar-free
breath mint.
