Many parents think that dental calculus is the patent of adults, but in fact, children usually do not pay much attention to the issue of brushing, or brushing is not very careful, plus do not rinse in time after eating, teeth will accumulate dirt, the formation of dental bacteria class, dental calculus, adults are through the dental cleaning to thoroughly clean the calculus, but also a large part of people think that dental cleaning will cause damage to teeth, that children how to do dental calculus? In the end, can you scaling? Causes of calculus Calculus is a calcified mass that is attached to the surface of the teeth. It is formed by the gradual calcification of mineral salt deposits in saliva on the basis of plaque on the tooth surface. Calcification occurs when calcium ions combine with the intercellular organic material protein-polysaccharide complex of dental plaque, and then calcium phosphate crystals are deposited on the intercellular material and bacteria. Calcification occurs and continues along the inner side of the plaque attached tooth surface and reaches its extreme point after about several months. Calculus is not deposited indefinitely due to chewing food, tongue and cheek pressure, etc. The formation of calculus is related to the metabolic condition of the body, and the factors that affect the deposition of calculus are: i. Failure to master the correct method of brushing or failure to develop oral hygiene habits such as brushing and rinsing. Second, the rough surface of the teeth, tooth alignment is not neat, there is not easy to clean the restoration, etc. Third, there is a certain relationship with dietary habits, such as if often eat soft and fine food, tartar deposition faster, on the contrary, the intake of rough food is hindered by tartar deposition. Fourth, the intake of sucrose more people, due to the formation of more plaque, soft tartar deposition more. Fifth, the intake of food containing more calcium and phosphorus components, the formation of tartar is faster. The speed, form and hardness of tartar formation varies from person to person, and in general newborn tartar takes twelve to fifteen hours. Rapidly formed calculus is softer and more fragmented than slowly formed calculus. All newly formed calculus is soft and hardens slowly over time as it calcifies. Therefore, when calculus is first formed, it can be easily removed by oral cleaning or brushing, but after calcification, it is not easy to remove. Calculus is a foreign body to the oral cavity, it will constantly stimulate the periodontal tissues, and will compress the gums, affecting the blood circulation, causing gum infections in the periodontal tissues, resulting in inflammation and recession of the gums and the formation of periodontal pockets. When the periodontal pockets are formed, it is easier to make the accumulation of food debris, plaque and calculus, and this new accumulation will further damage the deeper periodontal membrane, so the result of the continuous vicious circle, and finally all the periodontal support tissue is destroyed, and the tooth is finally extracted. As long as you choose a regular hospital, scaling is not harmful to children. In foreign countries, children also have the experience of scaling, parents should cultivate their children’s awareness of caring for their teeth early, starting from the child’s first milk teeth, taking the child to the dentist every year, starting scaling at the age of three, and having their sockets closed at a young age to prevent the risk of tooth decay. So it’s okay for children to have their teeth cleaned. Of course, not every child needs to have their teeth cleaned. When children have excessive calculus deposits or pigmentation on their teeth, parents can take them to have their teeth cleaned, which is a healthy process that will not affect our health. Preventing calculus Brushing is an easy and effective way to prevent the formation of calculus. Tartar deposits are formed gradually, from little to large. Regular brushing can remove the tartar and calculus that has just started to be deposited on the surface of the teeth in time. Therefore, you should insist on brushing your teeth. If you wait until the tartar deposits are thick and tightly attached, you must be assisted by a dentist to remove them. In addition, because of the high viscosity and sugar content of fine food, it is very easy to deposit on the tooth surface, so you should eat less fine food, or you must brush and rinse your teeth after eating. Especially, eating fine foods such as cookies and cakes before going to bed not only can easily form dental calculus, but also can cause tooth decay. Therefore, you should brush your teeth and keep good habits of oral hygiene.
