What are the causes of tooth discoloration and coloration

There are many factors that cause tooth staining, the main ones are the following:

Dental fluorosis is also known as dental fluorosis or plaque enamel. The disease has the characteristics of regional onset, mainly due to the high fluoride content in drinking water. In mild cases, the enamel on the surface of the teeth is cloudy, opaque and chalky; Moderate cases have yellow or brownish-yellow irregular plaques on the tooth surface; In severe cases, in addition to color changes, there are also tooth enamel defects.

Enamel hypoplasia is the lack of calcium, phosphorus and vitamins A and D in the surface of the tooth during the development process. or tooth development disorders caused by harmful factors. In mild cases, the enamel on the surface of the teeth is opaque and chalky, loose and rough, and can be yellowish-brown due to food staining. In severe cases, the enamel may be substantially defected, with a dimple or band-like absence, or even no enamel covering.

Tetracycline stained teeth During tooth development, especially in children under 8 years of age or pregnant women, if they take tetracycline drugs (such as tetracycline, oxytetracycline, doxycycline, doxycycline, etc.), it is easy to cause tooth discoloration, which is called tetracycline stained teeth. This is because tetracyclines can bind to calcium ions in tooth tissue to form stable tetracycline calcium salts, which gradually worsen with age and become stable after about 18 years of age. According to the coloring depth, it can be clinically divided into four degrees, and the tooth surface of the tetracycline tooth is uniform milky yellow or light yellow; The tooth surface of the second degree is uniform and unequal shades of brownish-yellow or grayish-yellow; The tooth surface of the third degree is uniform and unequal shades of pure gray, gray-brown or gray-black; In the fourth degree, the tooth surface is gray-brown or gray-black, and it can be combined with enamel hypoplasia and tooth tissue defects.

Milky teeth are an autosomal dominant disorder and are less common. The affected tooth has a unique violet-blue change, the exposed dentin is shiny, translucent yellow-brown, the tooth is easy to wear, and the severe case is stump-like.

Tooth decay, commonly known as tooth decay or tooth decay, is caused by the digestion of carbohydrate foods to produce acid and corrode the tooth body with the participation of bacteria, causing the teeth to soften over time and the tooth tissue to disintegrate, forming black cavities.

Dead pulp discolored teeth are mostly discolored due to deep caries bacterial infection or direct violent blows, and the tooth is accidentally broken, resulting in pulp damage and necrosis and discoloration.

Normal and healthy teeth are pale yellow, which is the color of dentin revealed by tooth enamel.

However, a white cover is also applicable to the teeth, or many friends hope that the teeth can be whiter, so if you want to be white, you must first know what kind of tooth coloring you are.

There are two main cases of tooth discoloration, exogenous cigarettes, tea, coffee, red wine, and various food pigments caused by tooth coloring.

Endogenous is tetracycline tooth, fluorosis tooth due to tooth development defects caused by yellowing, blackening, stained spots, ordinary whitening effect is limited, you need to consider porcelain veneers as an aesthetic restoration method.

<> some tooth discoloration may be tooth decay or dead pulp teeth, and you need to go to a regular dental check-up in time.

The color of the teeth is not good-looking, and there are congenital factors that make the teeth dull or yellowish-brown

Genetics: Everyone's basic physiology is controlled by DNA, just like skin color, Caucasian people have less pigmentation and look whiter; Black people form more melanin and look black. If the parents' teeth are yellow, the child will also have yellowish teeth.

Developmental process: If there is a physiological disease in the process of tooth development, it will affect the formation of calcified dentin at that time, for example, due to high fever in childhood, the development of teeth is disturbed, resulting in uneven calcium precipitation, which will form plaques or uneven color on the tooth enamel.

Drug or food effects: Some drugs such as tetracycline can bind to calcium, and when calcium is transported to the teeth, it will enter the dentine by the way, causing an unsightly color, and now tetracycline is contraindicated in pregnant women and young children.

Disease effects: In children born with severe jaundice, too many red blood cells in the blood are destroyed, resulting in the inability of its metabolite bilirubin to be excreted in a timely manner, and there is light blue-blue or brown hemosiderosis in the dentin of primary teeth.

Environmental impact: In some areas, drinking water contains fluoride, and residents near the sea ingest a lot of marine food, which contains a lot of fluoride, and if the fluoride is overdosed, it will cause mottled teeth.

Teeth do not have a specific color.

Everyone's tooth color is different. Some are yellowish and some are white, all of which are normal colors.

It is mainly determined by the transparency of the enamel on the surface of the teeth. If the enamel mineralization is relatively complete, its transparency is high, and the color of the dentin below is revealed, and the dentin is yellow, so the tooth is yellowish. If the enamel is not mineralized, then its transparency is low, the dentin color is less exposed, and the tooth appears milky white.

Perfect teeth, I think health is naturally perfect.

The original color of the teeth is pale yellow.

The color of the tooth is determined by both the enamel and the dentin. Tooth enamel is the outermost layer of tissue, which is transparent and bright white, and the layer of tissue inside the dentin enamel is the tissue that encloses the pulp, and this layer of tissue is normally yellow. Therefore, the dentin penetrates through the enamel, and the color of the tooth is pale yellow.

Healthy teeth in the true sense of the word are actually pale yellow because the surface of the tooth is covered with a layer of enamel, which is transparent or translucent, and its deep dentin is pale yellow.

Why do some people's teeth have bright white teeth while others are really yellow and black? What are the causes of tooth discoloration? According to experts at ACE, there are several main causes of tooth discoloration:

1. Dead pulp tooth (trauma, caries, pulp necrosis) 2. Smoking, drinking tea, coffee, etc. 3. Iatrogenic tooth discoloration: such as tooth discoloration after plasticization**, after filling, desensitization**.

4. Tetracycline teeth (permanent teeth): caused by taking tetracycline drugs before the age of 7. Tetracycline can be deposited in the developing hard tissues of teeth, mainly in the dentin, giving the entire mouth a brown or brownish-yellow or grayish-brown color.

5. Dental fluorosis or enamel teeth: It is caused by living in areas with high fluoride content in drinking water before the age of 7. The pigment is in the enamel of the tooth surface, which is yellow-brown patches, and in severe cases, there are pitted and uneven defects on the surface of the teeth.

The incisors are usually the most visible. 6. Tooth enamel dysplasia and poor calcification: During the period of tooth development, due to systemic diseases, such as fever, viral infection, systemic infection, etc., which affect the body's metabolism and nutrient absorption, resulting in stage poor tooth development, resulting in defects or poor calcification in some areas of the crown, easy to collapse and destroy the tooth shape.

How to solve tooth discoloration? The best solution is to whiten your teeth with cold light. Finally, experts remind you that you must choose a regular plastic surgery hospital for whitening your teeth.

Normal teeth are shiny yellowish-white, and the change in color or color caused by changes in the body or teeth is called tooth discoloration, also known as endogenous tooth coloration. Tooth staining caused by the deposition of foreign pigments that enter the mouth or pigments produced by bacteria in the mouth on the tooth surface is called tooth exogenous staining.

What causes discoloration and blackening of teeth?

What causes tooth discoloration.

First, foreign coloring. Discoloration of teeth caused by the deposition of pigmented tartar.

Second, the coloring itself. It can be divided into the following types:

Tooth discoloration caused by taking tetracyclines, erythema caused by long-term consumption or consumption of too high concentrations of fluoride.

Poor development of teeth .

Discoloration caused by pulp lesions, pulp necrosis caused by trauma, impact, or root canal** may cause pale gray and dark brown discoloration.

It can be a manifestation of dental caries, pulpitis, usually do good oral hygiene, eat less sweets.

Suggestions: If you feel pain and discomfort, you can see a dentist and do a checkup.
