People want to have white teeth, but many people’s teeth will turn yellow and black. What causes the yellow teeth?
How should tooth become yellow?
The World Health Organization (WHO) defines oral health as clean, cary-free, pain-free and normally colored gums.
Many people want to have a white teeth, more than half of friends think their teeth are yellow and not white enough, and willing to take measures to whiten their teeth.
There are many reasons for tooth coloring and yellowing, which can be generally divided into two aspects: endogenous and exogenous tooth coloring.
Exogenous coloring is due to the presence of a variety of oral bacteria on the surface of the teeth, secreting viscous substances, combined with the daily food tea dirt, smoke stains and drinking water in some minerals adsorbed on these viscous substances, gradually make the teeth yellow and black.
Endogenous pigmentation is formed during tooth development, such as tetracycline deposited in the dentin, will make the tooth become yellow, brown or dark gray, called tetracycline teeth;
If there is too much fluoride in drinking water, it may also lead to dental fluorosis, white chalk, tan patches on the tooth surface;
Long-term tooth is not treated in time, infection leads to pulp nerve necrosis, combined with bacterial decomposition products will also make the tooth yellow and black.
A, tooth yellow reason 1, developmental factors in the process of development due to malnutrition, infectious diseases, high fever, serious illness, can make the teeth enamel hypoplasia and calcification is affected, the teeth will turn yellow and crispy, in this case the teeth of enamel lose luster, opaque, yellowish-brown, the person that weigh can make the teeth surface rough punctate, appearance is not complete,
Often symmetrical, developmental factors caused by dental nutritional disorders caused by poor calcification, reflecting the impact of the past health status on teeth, acquired calcium, vitamin D supplementation is meaningless.
Number 2, drug factors and this is our most people know that the “tetracycline tooth”, tetracycline drugs can lead to the occurrence of yellow teeth, the 60 s and seventy s, more extensive use of tetracycline drugs, can use this kind of drug overdose in tooth tissues savings, make the inner dyed yellow teeth, dental calcification period (baby teeth in the mother during pregnancy,
Permanent teeth in children before the age of seven) overdose of tetracycline is easy to cause tetracycline teeth, children generally wait until the age of seven years after the change of teeth yellow teeth.
3, hygiene factors do not pay attention to oral hygiene, not form a good habit of brushing your teeth, the tooth surface of a layer of food residue accumulation, soft dirt, plaque, YanZi, red wine, rice wine, tea, coffee, Chinese traditional medicine, these cases of yellowing teeth teeth isn’t yellow, is do not pay attention to oral hygiene, affects only the surface of the teeth color, is easy to remove.
4, water quality factors in some areas, especially mountainous areas, the water is high in fluoride, drinking this kind of fluorinated water will make the teeth yellow, involving the whole mouth teeth.
Fluoride has the effect of preventing caries, this kind of tooth is not prone to caries, we call it “dental fluorosis” or “dental fluorosis”, is the development of teeth calcification period, the human intake of excessive fluoride caused by natural water fluoride is too high, easy to lead to dental fluorosis, is a manifestation of endemic fluorosis.
Two treatment method according to the teeth, teeth yellow, the depth of the color is yellow, the reasons of cleaning should be taken, whitening toothpaste, tooth bleaching, white teeth stick and PFM restoration different ways such as white, no matter adopt what kind of teeth whitening method, must ensure that dental caries and periodontal disease has finished treatment, under the situation of dental health.
Otherwise, it will aggravate dental diseases.
1, white tooth paste the latest popular tooth whitening method, convenient, fast, simple, cheap, abroad has been popular for a long time, the clinical effect is relatively obvious, there is a trend of gradually replacing bleaching.
However, white tooth paste is also not suitable for tetracycline teeth, dental fluorosis and other teeth have discolored dentin.
2, cold light whitening technology cold light irradiation by special cover on the tooth bleaching agent, to make it in a short period of time into the tooth hard tissue to achieve change color, the purpose of tooth hard tissue, its advantage is not damage operation treatment time about 30 to 45 minutes, but deficiency is due to the effect of bleaching, bleaching effect varies from person to person.
3, cleaning many people think that cleaning is tooth beauty whitening, in fact, the main role of cleaning is not whitening, but a method of conventional dental care, mainly to prevent dental caries, gingival, periodontal disease conventional health care method, aimed at the tooth surface stone, dental plaque.
It is a good habit to clean your teeth by having regular semi-annual cleanings.
Although the purpose of dental cleaning is not to whiten teeth, clean teeth will naturally look whiter.
4, whitening toothpaste basically not too much of a whitening effect, mainly through physical contact between abrasive and spots on the surface of the teeth, some whitening toothpaste also joined the oxidant, but due to the less chemical component content, general short time brushing your teeth, after long time placement easy failure, so the whitening effect is very small.
If the tooth color is not too black too yellow, the use of whitening toothpaste and a certain role in maintaining and promoting;
However, if there are obvious stains, tobacco stains, wine stains, tea stains, coffee stains, traditional Chinese medicine and other pigments on the tooth surface, the whitening toothpaste has no effect at all.
5. Tooth bleaching is suitable for moderate and mild discoloration of teeth. The method of bleaching and beauty is applicable to a wide range of people and people over 18 years old.
However, tetracycline teeth, dental fluorosis and other dentin has discolored teeth, the use of ordinary bleaching method is difficult to achieve a good whitening effect.
Bleaching is to mold a set of braces according to the shape of the teeth. Every night before going to bed, put bleach on the braces and put it on the teeth.
The bleach is made of 30 percent hydrogen peroxide, which reacts with melanin on teeth to restore their natural color.
Small risk, quick effect, no damage to gingiva and pulp, the course of treatment is generally about one month, the longest can not exceed 3 months;
Some people feel sore teeth during bleaching and are sensitive to heat and cold. This is a normal reaction and will return to normal when the treatment is complete.
The effect of tooth bleaching is not the same for everyone. In order to achieve the best whitening effect, you can bleach several times repeatedly, and do not exceed three courses of treatment at most, otherwise there is some damage to the teeth.
6. Restoration and treatment methods Porcelain veneer or porcelain tooth restoration method is an ideal way to beautify the cracked and incomplete teeth.
Need to pay attention, if only to whitening normal grinding teeth small, combined with porcelain teeth set, this is not worth the cost, or have a certain effect on the teeth, because repair treatment method is to need to grind except the part of the natural teeth, covered with artificial PFM cover or porcelain teeth in teeth corresponding place, advantage is that the teeth color change obviously,
The disadvantage is that part of the natural tooth must be removed, and there is a possibility of complications due to pulp irritation.
Note: severe discolored teeth and people with higher requirements for changing tooth color should not be treated with bleaching;
A LOT OF PEOPLE ONE-SIDED PURSUIT of teeth white and beautiful, LITTLE people do not know that normal teeth are light yellow originally, this kind of color of tooth enamel mineralization is good, calcification degree is high, through translucent enamel shows the dentin color much.
