The teeth are yellowed and ugly

There are usually two reasons for the yellowing of teeth, one is tooth mineralization, such as tetracycline teeth, fluoride calcium plaque, because the drug damages the enamel, this situation is that the tooth surface is not shiny, yellow, gray and black;

The other is due to people who smoke regularly, drink tea, drink coffee, or do not like to brush their teeth, which form stains on the tooth surface and turn yellow.

You said that the yellowing is more even, and there is a better brushing habit, if you don't have the habit of drinking tea and coffee, it is likely to be the first type.

In the above two cases, toothpaste alone will definitely not be effective in removing yellowing, if it is the second case, ultra-raw wave tooth cleaning can be improved for a while, but if the eating habits are not changed, soon the tooth stains will reattach to the tooth surface, and the tooth cleaning is too frequent, not only painful, but also definitely damage to the tooth itself.

Don't try any chemical whitening either, as it is extremely harmful to your teeth.

In response to the situation you mentioned, you may wish to try tooth ** chewable tablets, but if it is a tetracycline tooth in the first case, it is definitely impossible to restore the white brightness before it was not damaged, but it must be significantly whiter than before it was not used, and the tooth surface will return to a healthy luster.

If it is the second type of tooth stain, it can be significantly removed and whitened in about a month.

There are reasons why teeth are black and yellow, and there are none other than the following.

1. Dental fluorosis If you live in a high fluoride area since childhood, it will cause dental fluorosis, yellowing and gray teeth, chalk spots on them, and some enamel punctate or band-like defects.

2. Tetracycline teeth Taking tetracycline (an antibiotic) during infancy or even during pregnancy will cause teeth to turn grayish-brown.

3. Exogenous coloring.

4. Dead pulp teeth.

**Word 1: Go to the Department of Oral Medicine for tooth bleaching, but it can only work on mild to moderate dental fluorosistetracycline teeth, and the landlord's situation may not be suitable.

2: Use the method of restoration**, ask the prosthodontist for the specific method.

Age-related changes.

As we age, our teeth wear out over the course of long-term use. When the enamel on the surface of the tooth becomes thinner and thinner, the yellowish color of the inner layer of the tooth will be more and more transparent, and the tooth will appear more and more yellow.

Water quality factors. On the one hand, fluoride increases tooth enamel and makes it stronger, and on the other hand, it also causes teeth to gradually turn yellow. Mineral water contains a lot of fluoride, and drinking too much of it can make your teeth lose color!

Pharmacological factors. The tooth has been treated with tetracycline medication during development, resulting in tetracycline teeth.

Tooth coloring. In addition to the yellowing of teeth with age, diet can also contribute to tooth staining.

The outermost structure of the tooth is the enamel, which has a certain permeability. Some coloured foods and beverages can be deposited into the tooth through tooth enamel, which can easily stain tooth enamel by these pigmentogens and extremely pigmented small molecules.

Examples: Coke, tea, soda, and sports drinks.

Although colorless carbonated drinks do not cause tooth staining, the acidity in them can still erode tooth enamel, and studies have shown that many so-called sports drinks are more destructive than cola

2. Water quality factors: In some areas, especially in some mountainous areas, due to the high fluoride content in the water, too much fluoride drinking will turn yellow, and it is not 1-2 teeth, it is a mouth full of big yellow teeth. Fluoride has a caries-preventing effect, so these people are less susceptible to tooth decay (tooth decay).

3. Drug factors: Most people now know that tetracyclines can lead to the occurrence of yellow teeth, especially in children (before the age of 5).

4. Hygiene habits: Some people do not pay attention to oral hygiene, do not have the habit of brushing their teeth in the morning and evening, and accumulate a layer of food residues, soft scale, tartar, smoke stains, tea stains, etc. on the surface of their teeth. These "yellow teeth" are not the yellowing of the teeth themselves, but are caused by not paying attention to oral hygiene.

The best methods for yellow teeth are: in addition to paying attention to hygiene habits and brushing teeth correctly, you need to go to the hospital to do tooth bleaching, there are several kinds of tooth bleaching agents, the effect is not bad, but most of them are expensive; Light curing** is to cover the surface of the tooth with a layer of resin similar to the color of the tooth, and then use a special light to illuminate, this method is beautiful, convenient, fast, less costly, and the degree of firmness is slightly worse; Conditional porcelain teeth, preferably porcelain veneers, can achieve the real and is the ideal restoration method, the disadvantage is to grind out part of the teeth, the cost is expensive.

Teeth can be said to be a calling card of a person. When you smile, it's a wonderful thing to show a mouthful of teeth that sparkle white shine. Regardless of whether you are male or female, if your teeth are white and neat, and your breath is fresh, it must give a good impression; If your teeth are yellow, people's impression of you is greatly reduced.

A charming smile must be white teeth, white teeth, even if you are not white, facial features are average, it can also add a lot of points for you, regardless of men and women, having a mouth of white teeth must be enviable. We brush our teeth carefully every day, why do our teeth not turn white, but turn yellow day by day?

It is difficult to make teeth white just by brushing teeth, not to mention that many people do not brush every tooth when brushing their teeth, and the gaps between the teeth are not brushed clean, and the tooth stains accumulate and the teeth are naturally yellow. Today I will tell you what are the good habits of people with white teeth, and how you have big white teeth!

1. Use an electric toothbrush to brush your teeth.

Many people are accustomed to brushing their teeth so-so, and as a result, a lot of bacteria and food remain on their teeth, and over time, not only the teeth turn yellow, plaque appears, but also stubborn tartar can be formed. Compared to manual toothbrushes, electric toothbrushes rely on the high-speed vibration of the bristles to clean not only the surface of the teeth, but also the deep between the teeth. And now many electric toothbrushes come with whitening and polishing functions, which can effectively whiten teeth.

2. Rinse your mouth after eating.

Even if you use water to rinse your mouth, it is also excellent for your teeth, especially after drinking coffee and red wine, you must rinse your mouth to avoid pigmentation and staining your teeth. Many people don't have a good habit of rinsing their mouths after meals, and their teeth turn yellow day by day.

3. Replace toothpaste in time.

When buying toothpaste, you can check the type of friction agent by looking at the outer packaging, and the better choice is hydrated silica, which is relatively mild and delicate, and has no graininess. Secondly, the toothpaste should be replaced in time according to the oral condition, do not use a certain toothpaste for a long time, especially do not use a drug-based toothpaste for a long time.

Long-term use of fluoride toothpaste, the probability of dental fluorosis will increase by 50%, with fluorosis, the teeth are yellow, the enamel on the surface of the teeth will appear chalky streaks, showing brownish-yellow or brownish-black plaques, the teeth are not shiny, and there are chips, which makes it difficult to brush the teeth, and bacteria are easy to breed over time. In addition, the original strong teeth will become brittle.

Healthy teeth are naturally slightly yellowish and shiny, which do not look so white from time to time, and are not as white as paper but a little yellowish. Because the outer layer of the tooth is enamel, which is translucent, and the color of the dentin in the naïve inner layer is not white, but yellowish, and its color will partially penetrate the enamel, so that the tooth color has a certain yellow.

Exogenous coloration. There are many kinds of bacteria on the surface of the teeth, which secrete many sticky substances, and the food residues, coffee, red wine, tea dirt, and smoke stains in the daily diet are adsorbed on these sticky substances, and gradually turn the teeth yellow or black.

Endogenous coloration. It is formed during the development of teeth, such as tetracycline deposition, which causes the teeth to turn yellow, brown or dark gray, called tetracycline teeth; If there is too much fluoride in drinking water, it will lead to dental fluorosis, and the tooth surface will appear white chalk-colored and tan patches; Tooth nerve necrosis can also darken the tooth if it binds to bacterial breakdown products.

But as long as you can continue to stop smoking, drinking alcohol and coffee, your teeth can improve.

There is another way: use the same amount of salt and soda, add water and mix it into a paste, use it with a toothbrush 1 2 times every l, long-term use can also make the teeth white.

In addition, cigarette stains on smokers' teeth are much easier to remove.

Before brushing your teeth every night, take half a mouthful of vinegar in your mouth, sip it for 2 3 minutes and then spit it out, then wash it with a toothbrush (without toothpaste), and then wash it with water, usually 2 3 times to see the effect.

Yellowing of teeth is related to drinking tea, and whether you smoke or something, so it is easy to turn yellow. Brushing should also be done correctly, generally brushing for 3 to 5 minutes.

There are many factors that cause yellowing of our teeth, such as the accumulation and attachment of dental calculus for a long time, or the congenital dentin, which will cause the teeth to become more and more yellow.

The main reasons why some people have particularly yellow teeth are as follows:

One is external staining, smoking, drinking coffee, eating curry, etc. can easily cause external pigments to attach to the teeth, making the teeth yellow, and these pigments can be removed by scaling or sandblasting;

The second is the internalization of external staining, for example, tooth decay will go through the process from white to yellow to black, the external color will slowly penetrate into the inside of the tooth, and the surface enamel layer is defected, and the color will penetrate into the inside of the tooth;

The third is the color of the inside of the tooth, for example, some drugs will cause the color of the tooth to change, the necrosis of the tooth makes the tooth slowly turn yellow and black, and with the increase of age, the enamel will become thinner and thinner, and the color of the dentin will also appear.
