Calcification of dental calculus occurs over time. Because dental calculus is made up of some calcium phosphate and water, some organic manganese sulfate, and some minerals, it will appear some yellow or brown, and some may be black. Dental calculus is generally an important cause of periodontal disease, so patients must pay attention to good oral hygiene, clean their teeth thoroughly, and clean their teeth regularly to effectively remove dental calculus.
Calculus is usually deposited on the surface of the tooth, on the lingual surface of some anterior teeth in the lower jaw, or on the neck of certain tooth roots, and on the surface of some teeth where the oral mucosa cannot be moved. Long-term dental calculus can lead to some chronic gingivitis in patients, and patients are advised to pay attention to oral hygiene in their daily life.

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.
The stone generally refers to the small rock mass that falls off by the external force of the large rock mass, mostly attached to the surface of the large rock mass, generally into a block or oval, the appearance is rough, some are smooth, and the texture is firm and brittle. It is generally composed of calcium carbonate and silicon dioxide.
So how does dental calculus form?
Every time you finish eating or all kinds of snacks, your teeth chew the food by chewing, and some of the residue will form plaque, which is the predecessor of dental calculus, which will calcify under the soaking of saliva and become dental calculus after a long time of accumulation, coupled with the lack of attention to the cleaning of the mouth.
In addition, it is important to note that the speed, shape and hardness of calculus formation vary from person to person, but generally speaking, it only takes 12-15 hours for new calculus to form. Rapid formation of dental calculus is softer and more crumbly than slow formation.
-
Dental calculus is a milky white scale at the beginning, and it will gradually calcify and harden over time. Because dental calculus is composed of some calcium phosphate and water, and some organic manganese sulfate, and some minerals, it will appear some yellow or brown, and some may be black.
-
Because you don't brush your teeth thoroughly, the food will become hard if it settles over time.
-
Because dental calculus is formed by the gradual accumulation of food residues in the teeth and then calcification and hardening.
It is composed of 75 calcium phosphate, 15-25 water, organic matter, manganese phosphate, calcium mineral acid and trace amounts of potassium, sodium, iron, and has a certain hardness.
-
Calculus. At first, it is a milky white scale, but over time it will gradually calcify and harden. Because calculus it is made up of some calcium phosphate and water, and some organic manganese sulfate, some minerals.
-
Of course, it will be very hard if it has been petrified, brush your teeth well every day, and use a good toothpaste to remove the calculus.

There's nothing to say about this kind of thing, it's all the same, let's go to the hospital to get your teeth cleaned! No fuss.

Diamond has a hardness of 10 on the Mohs scale and a microhardness of 98 MPa (100 060 kg mm2), which is more than 1 000 times the absolute hardness of quartz and 150 times that of corundum.
Actually, it's not the teeth that are hard, it's the enamel on the surface of the teeth. Enamel is a highly calcified tissue that contains more than 96% of inorganic salts such as calcium, magnesium, and phosphorus. The hardness of enamel is 8, which is 2 levels softer than diamond, and as hard as topaz in stone!
So diamonds are harder than teeth!
-
The diamond is hard, the teeth are mainly calcium structure, and the diamond is C60

The reason for the formation of very hard dental calculus around the teeth is relatively simple, first of all, you often eat those foods that hurt your teeth, such as betel nut, or those substances such as lemons containing acidic substances, teacher, if you eat those things, it will make your teeth corrode quickly, and damage the tooth enamel, forming serious calculus around the teeth, and there is also a residue of food that usually does not pay attention to the cleaning of the teeth, and it is easy to form a cavity and become a bacterial breeding if left between the teeth, resulting in dental calculus.
-
These calculus are the result of not brushing our teeth properly. Usually we don't rinse our mouths very well when we eat, so that all the residue of the food is left in the gap between our teeth, and then the potato is lost over time, and now it is very hard tartar.
-
It is because of the low concentration of carbon dioxide in the mouth and the precipitation of inorganic salts on the surface of the tooth, which leads to calculus.

The process of tooth development is quite long and complex, and the teeth begin to develop and grow during the fetal period before the baby is born. The main component of teeth is calcium. Around the seventh week of pregnancy, the baby teeth begin to develop, first forming the baby tooth germ, which resembles the "germ" of the tooth.
By about five months of pregnancy, the fetus has basically formed the cusps of baby teeth. By the time of seven months of pregnancy, the fetus's primary tooth crowns will form about 1 2; By the time the baby is born, almost all of the 20 baby teeth have formed crowns.
At the same time as the baby teeth grow, the permanent teeth are also quietly brewing, and the permanent tooth germ also begins to develop gradually in the fourth or fifth month of pregnancy, but the calcification of the permanent teeth is mostly after birth.
It starts gradually, and does not grow until the baby is six months old. In other words, when the child is born, there are already 20 baby tooth germs and 16 permanent tooth germs in the jawbone. Although you can't see the teeth in your baby's mouth when they croak, this is because they are hidden under the gums (commonly known as "gums") and have not yet grown.
It is not until about half a year of age that the first tooth comes out from under the baby's gumbed. By the time the child is two-and-a-half to three-year-old, the child's small baby teeth (20) will be ready to grow.

It is made of calcium.

Calcium Teeth are not very hard.

It's not serious, it's okay to go to the hospital for tooth cleaning**, but if you don't do it in time**, it can lead to gum recession, bleeding, etc., so the teeth are easy to loosen and cause loss You better go to the hospital**!
It may be a cracked tooth, so go to the hospital for a check-up.
1.In fact, the reason why the bread is baked and hard is very simple, that is, there are two points that you may not do well in the production process, the first point: the dough is not kneaded well enough (that is, the gluten is not kneaded together). >>>More
Tooth decay is the most common dental disease, which is a disease in which the inorganic parts of the teeth are decalcified and the organic parts are destroyed. >>>More
In the past 20 years, our basic midsole technology is EVA foam material, of course, with the new technology, the addition of other components to EVA foam itself has also made many midsoles more comfortable than the previous ones, but no matter how to add, EVA material itself is soft, long-term wear, the sole will still leave dents. >>>More
