Exogenous coloring is caused by the bacteria on the surface of teeth. These
bacteria can secrete lots of sticky substance.Isimile shanghai dental clinic piont it
out that tea spots, smoke stains and
minerals in the drinking water adhere to the sticky substance making teeth
become yellow or black gradually. For exogenous shaded teeth, coffee, tea,
smoking and red wine are the culprit. According to statistics, there are 15% ~
25% of smokers in China. The female smokers are also included.
That is to say, there are 200 to 300 million people who have yellow or black
teeth in China. Besides, the impact of coffee, wine and tea should not be
neglected. Nowadays due to the pressure from work and study, people are used to
drinking tea, coke, coffee, etc. Once the pigment from the food deposits on the
teeth, it is difficult to remove. Our daily life can’t be without water. With
the continuous improvement of living standard, people require water with higher
quality. This need not doubt that only clean water can ensure our health. At the
same time, the water quality is closely linked with our dental health. For the
sake of our teeth, the content of fluoride in water can’t be too high.
On the other hand, endogenous coloring was formed in the process of tooth
development. The fact proved that tetracycline drugs can lead to dark or yellow
teeth. Especially if the children take drugs before the age of 7 to 8, the
influence is greater. When tetracycline deposits in your teeth, they will turn
yellow, brown, or dark gray. There is another kind of situation that the
excessive fluoride in drinking water can lead to dental fluorosis. Sometimes
black teeth are caused by gums problems such as periodontitis. If the necrotic
nerves are combined with bacterial decomposition products, they can also make
teeth black. What’s more, body health can ensure the normal development of
teeth. From childhood the color teeth change slowly from white to beige because
of the loss of calcium. If the human body lacks calcium, phosphorus, and
vitamins A, D, etc, teeth will be loose, rough and even defective. Then the
teeth are more likely to be colored. Thereby the likelihood of black teeth will
increase.
An important reason for yellow or black teeth is people’s bad living habits.
Some people don't pay attention to oral hygiene and do not have the habit of
brushing teeth in the morning and evening. There are lots of food scraps, soft
dirt, plaques and smoke stains on the surface of teeth. Then the teeth turn
yellow or black slowly. In terms of brushing your teeth, the right toothpaste
and toothbrush can bring more obvious cleaning effects. In addition to brushing
teeth, the professional dental care is necessary. Especially the elderly and
children should pay more attention to protecting teeth.
Tips: Foods that are firm or crisp help clean teeth as they're eaten. We already
mentioned apples (otherwise known as nature's toothbrush); other choices include
raw carrots, celery, and popcorn.
