How do you get yellow? What s the deal with tooth yellow?

Exogenous: There are a variety of bacteria on the surface of the teeth, they are secreting many sticky substances all the time, and daily diet such as drinking tea, drinking coffee, smoking, etc. will leave pigments on our teeth, which are adsorbed on the sticky substances secreted by bacteria, and gradually make the tooth surface yellow or black. Over time, these substances can gradually invade the inside of the tooth from the surface of the tooth, forming internal stains and slowly discoloring the inside of the tooth.

Endogenous: Pigmentation occurs during tooth color development, in addition to genetic factors, the most common but often overlooked is the yellowing of teeth due to age, or tetracycline teeth caused by drugs, dental fluorosis caused by poor water quality, etc.

A more common reason is that some people like to drink cola, cocoa, coffee and other beverages, or drink strong tea, these drinks have a substance called pigment, when the drink is drunk, a small amount will remain in the mouth, and the pigment will be deposited on the teeth. Over time, the surface of the tooth will turn yellowish-brown or even black-brown. At this time, even if you brush your teeth vigorously, it often doesn't help.

Therefore, after drinking this type of drink, you should rinse your mouth with water to rinse off the pigment of the drink that remains on the surface of your teeth, and the same goes for smoking.

Another reason is that oral hygiene is not maintained well, and after eating or snaking, there are food residues between the teeth or on the surface of the teeth, which forms tartar over time and makes the teeth yellow. At this time, it is not easy to brush off the teeth by brushing alone, and you need to go to the hospital for tooth cleaning**, scrape off the dirt on the teeth, or use drugs to corrode the dirt off.

The causes of yellowing, staining of teeth are mainly related to the following factors:

One is the health factor: due to poor nutrition or illness in the development of closed smile teeth, the calcification of the teeth will be affected, and the teeth will be yellow and brittle;

The second is the water quality factor: in some areas, especially in some mountainous areas, due to the high fluoride content in the water, the teeth will be yellow, and it is not 1 or 2 teeth, it is a mouth full of big yellow teeth.

It is recommended to brush your teeth with the tooth cleaning and white formula when brushing your teeth, which can effectively change the problem of yellow teeth in the car chain.

It has something to do with eating, and it is necessary to brush your teeth every day, brush your teeth clean, don't use too much force, otherwise the enamel on your teeth will become thinner, and it is estimated that your enamel will become thinner, but don't worry. Go to the dental hospital to get your teeth cleaned.

It may be caused by too much of an element in the body, or it may be the accumulation of tartar and yellowing caused by frequent brushing.

It is closely related to the growing environment and diet.

The most common is tetracycline teeth. In our country.

In the 60s and 70s, tetracyclines were widely used, and excessive use of such drugs could accumulate in the tooth tissue, causing the inner layer of the tooth to stain and turn yellow. Tetracycline does not immediately turn the teeth yellow, but it is during the calcification period of the teeth (baby teeth are pregnant in the mother's pregnancy, and permanent teeth are before the child's age of seven) that the tetracycline tooth is caused by overdose. In the case of permanent teeth, they took an overdose of medication before the age of 7 and did not show yellow teeth until they were replaced after the age of 7.

At that time, it was difficult for doctors and parents to associate the use of tetracycline with tooth discoloration, and it was later confirmed by scientific research that the disease was related to tetracycline.

Another type of tooth that often causes yellowing of teeth is dental fluorosis. Dental fluorosis is caused by excessive intake of fluoride by the human body during the calcification period of tooth development, and the intake of fluoride is mainly through drinking water. In some areas of China, the fluoride content in natural water is too high, which can easily lead to dental fluorosis, which is a manifestation of endemic fluorosis.

In addition, in the period of calcification of children's tooth development, the disease course is relatively long, which affects the nutritional metabolism function of the whole body, and can also affect the tooth enamel hypoplasia and poor calcification, it is characterized by the loss of luster on the surface of the enamel, opaque, yellow-brown, and the heavy can make the tooth surface into rough spots, the shape is incomplete, the tooth is often symmetrical, although the disease is a nutritional disorder caused by poor calcification, but only reflects the impact of the past health status on the teeth. Therefore, it is meaningless to supplement calcium and vitamins after poor calcification of teeth.

The acquired factors that make teeth yellow mainly include smoking, drinking strong tea, drinking coffee, and eating certain traditional Chinese medicines, which only affect the surface color of the teeth and are easy to remove.

There are many reasons for the yellowing of teeth because there are many bacteria on the surface of the teeth, which secrete many sticky substances on the surface of the teeth, such as many men drink tea and smoke at the same time, and the tea scale, smoke stains, and some minerals in drinking water and minerals in people's saliva adsorb on these sticky substances to form plaque and tartar, which gradually turns the teeth yellow or black.

Usually during the development of teeth, if tetracycline is deposited in the dentin, it will cause the tooth to turn yellow, brown or dark gray, which is called tetracycline tooth; If there is too much fluoride in the drinking water, it can also lead to dental fluorosis, which is a white chalk-colored and tan plaque on the tooth surface; If the nerve dies in the tooth, hemoglobin can also darken the tooth by combining with bacterial breakdown products.

Many toothpaste brands will have a series of medicated toothpaste, as the saying goes, "medicine is poisonous", and medicated toothpaste is no exception, although this toothpaste can control the production of pathogenic bacteria, but it can also destroy the "ecological balance" in the mouth and cause new infections. What's more, the alkaloids in medicated toothpaste can damage the enamel on the surface of the teeth, making the teeth tarnished!

4. Mineral water.

It can be said that most people have bought mineral water, and the fluoride contained in mineral water can increase tooth enamel and make it stronger on the one hand, and on the other hand, it will gradually turn the teeth yellow. Mineral water contains a lot of fluoride, drinking too much, will make your mouthful of white teeth discolored, it is recommended to drink at least 1000 ml of white water per person per day, of which the intake of mineral water should not exceed 300 ml, the remaining 700 ml, you can drink purified water or boiled tap water.
