What is tartar? What is the color of tartar?

Dental calculus is a stone-like deposit of bacteria in the mouth, food debris and calcium and phosphorus plasma deposits in the mouth, which are firmly attached to the teeth. Bounded by the gingival margin, the tartar above the gingiva is called supragingival calculus, which is yellow or white in color and large in volume, and has more deposits on the tooth surface where the opening of the salivary duct meets the lower lingual side of the anterior teeth; The tartar that is covered by the gums under the gums is called subgingival calculus, which is black or brown in color, small in size, hard in texture, and more harmful than supragingival calculus. Both supragingival and subgingival stones will not be removed by brushing and can only be removed by mechanical removal, so it is recommended to clean your teeth every six months to a year.

How is dental calculus formed?

The formation of dental calculus is mainly caused by the minerals contained in human saliva, which react with the acidic secretions in the mouth, and the physiological needs of people determine that people must secrete a large amount of saliva every day.

Due to saliva secretion, the minerals in saliva have the conditions for long-term continuous reaction with the acidic liquid in the mouth, and this long-term reaction produces acidic compounds, which become the prototype of tooth "stone", and these reactants are easy to attach to the back of the teeth, the junction between the gums and the teeth, and other places that are difficult to clean by brushing, and after a long time, they become stubborn and difficult to remove derivatives - dental calculus.

Types of dental calculus.

Supragingival calculus.

It is also called visible calculus, which is generally covered between the teeth, the back of the teeth, and the root of the teeth, and can be seen by the naked eye.

Subgingival calculus.

Also known as invisible calculus, this type of calculus has invaded under the gums, usually accompanied by bleeding gums, which cannot be seen by the naked eye.

Classification of dental calculus.

0 degrees: no soft scale and dental calculus.

Grade 1: A little scale or calculus, but not more than L 3 of the tooth surface.

2nd degree: calculus, not more than 1 3 of the crown surface, with a small amount of subgingival calculus.

3rd degree: calculus does not exceed 2 3 of the crown surface, and there are more subgingival calculus.

However, dental calculus does not cause bad breath Authoritative studies have found that bad breath is caused by anaerobic bacteria in the mouth breaking down sulfur-containing proteins to produce volatile sulfides (VSCs). Sulfur protein** in the intestinal tract. The fecal reefs in the intestine will continuously release sulfur-containing proteins, which will be extended to the mouth, where they are broken down by anaerobic bacteria in the mouth to produce volatile sulfides (VSCs), which are released from the back of the tongue and throat, resulting in bad breath.

Note: Sulfide (VSC) is a volatile gas with an unpleasant odor and a disgusting taste.

Poor oral hygiene, soft scale adheres to the tooth surface, especially the gingival margin, and the soft scale gradually calcifies to form dental calculus. Once the tartar has formed, it cannot be removed by brushing the teeth, and a periodontal foundation is required**. Periodontal basis** is divided into supragingival scaling and subgingival scaling.

Supragingival scaling is the removal of tartar above the gums and exposed to the tooth surface, which can be removed with an ultrasonic scaling instrument.

Hello! Calculus is the yellowish, white, yellow-white layer that covers the root of the tooth or between the teeth. Tartar is the main carrier of periodontal bacteria, that is, the root cause of periodontitis, the number one killer of oral health, and of course it is a great threat to oral health.

It is formed due to poor oral hygiene, calcium and phosphorus deposition under the action of bacteria, including deposits of epithelium, bacteria, mucins in saliva and mineral salts in saliva shed by the mouth. Its main component is calcium phosphate, followed by magnesium phosphate and calcium carbonate, and organic matter accounts for a small part. This calcium and phosphorus deposition is slow and can be removed at any time if you brush your teeth regularly, otherwise it will accumulate more and more thickly.

In addition, for some reason, if one side of the chewing habit is used, the tooth on the side that is not used loses the friction effect of food, and more calculus can be deposited. There are two options for calculus removal: one is to go to the hospital for ultrasonic scaling, which has the advantage of being effective quickly, and the disadvantage is that the scaling process is more painful and there is a risk of cross-infection of blood; The second is that you can also use biological products, such as dental ** biological tooth cleaning, the advantage is that it is bitter, non-natural, and there is no risk of cross-infection at all, and at the same time of biological tooth cleaning, it can also play a role in gum recession, the disadvantage is that compared with ultrasonic tooth cleaning, it is relatively slow to remove tartar, because it is the principle of natural dissolution of tartar, so it requires a certain amount of patience.

1. Dental calculus, also known as tartar, is usually found on the surface of the tooth at the opening of the salivary gland. The lingual surface of the lower anterior teeth, the buccal surface of the posterior teeth of the upper jaw, the neck of the teeth, and the surface of the teeth where the oral mucosa cannot be moved.

2. The calculus of the branches and teeth begins to be milky white and soft, and will become sensitive and hard due to gradual calcification. It is composed of 75% calcium phosphate, 15% 25% water, organic matter, manganese phosphate, calcium mineral acid and trace amounts of potassium, sodium and iron. and appear yellow, brown, or black.

3. Calculus is an important genogen in the development of periodontal disease. Without good oral hygiene, calculus can easily re-deposit on the surface of your teeth, even after a thorough cleaning.
