1. Do not pay attention to oral hygiene, such as not gargling after meals, not brushing your teeth before going to bed, and leaving food residue between your teeth, which creates good conditions for bacterial activities. After a long time, teeth will inevitably be corroded and damaged.
2. Poor diet: People who like to eat sour and sweet food or have the habit of eating snacks are likely to cause dental caries. Often eat sugar or sweets, the sugar left in the mouth is not easy to be completely removed. At this time, streptococcus in the mouth will decompose sucrose into glucose and fructose, and form long polymers of glucose and fructose. When these substances cover the teeth, they will form dental caries spots, and then they will ferment under the action of bacteria to generate acid, so that the calcium that constitutes the teeth will gradually dissolve and fall off when exposed to acid for a long time. At first, it will damage the enamel, and when the caries develop further, it will damage the dentin.
3. Lack of certain nutrients: Calcium and phosphorus are the main raw materials for teeth. Whether infants or teenagers, insufficient calcium intake will affect the firmness of teeth. After calcium deficiency, teeth will become loose and more easily corroded to form cavities.
Vitamin D can help calcium and phosphorus to absorb grazing, and vitamin A can increase the resistance of gingival mucosa. If vitamin A and vitamin D are insufficient, it can also indirectly contribute to the formation of dental caries.
4. Fluorine deficiency: Although the content of fluoride in teeth is very small, it is also an indispensable and important component of teeth. Long-term drinking water is short of fluorine, for example, if the fluorine content in each liter of water is less than 0.5 mg, dental caries may occur.
Although there are many factors that cause dental caries, they are most closely related to the food eaten, bacteria in the mouth and the body's ability to prevent dental caries, especially the body's ability to prevent dental caries. The caries prevention ability of the body is related to the fluorine content in the hard tissue of teeth.
To prevent and treat dental caries, besides paying attention to oral hygiene, diet is also very important.
[Dietary principles] 1. Eat more foods rich in calcium, phosphorus, vitamins A and D, and supplement milk, liver, eggs, meat, fish, tofu, shrimp skin, colored vegetables and fruits.
2. Eat foods with high fluorine content, such as marine animals, plants, fish, shrimp, kelp, jellyfish, laver and animal glue such as skin and tendons.
3. Develop the habit of drinking tea: China has had the custom of drinking tea and gargling with tea to prevent dental caries since ancient times. For example, in the Song Dynasty, when Su Shi talked about the way of keeping in good health, he pointed out: "I have a method that I have always cherished. Rinse your mouth with strong tea every time you eat, it will get tired, but the spleen and stomach don't know. Anything with meat between your teeth should be soaked in tea, so you are too lazy to take it off. As soon as your teeth are washed, it will gradually become dense and hurt. However, in the past, you used middle and lower levels of tea, but the upper level was not frequent, so you sipped it every few days. Yuanfeng 6th year (1086) August 23rd. " This is the earliest record of using tea to prevent caries.
Tea is a kind of beverage with high fluorine content. In recent years, some major tea-producing countries have attached great importance to the study of using tea to prevent dental caries. The fluorine content of tea is expressed in PPm, and the content is recorded in brackets after the variety:
Yunnan first-class Dianhong (54.0), Anhui first-class Qi Hong (47.0), Sichuan first-class Chuanhong (49.0), Jiangxi first-class Ninghong (34.0), Fujian second-class color species (88.0), Jiangxi first-class Wulv (62.0), Anhui first-class Tunlv (83.0), and Zhejiang first-class bamboo tea (83.0). Steamed green (2 12.5), Sichuan secondary fried green (58.0), Sichuan Kang brick (430.0), Guangxi Fu brick (5210.5), Anhua black brick (467.5), Anhua black tea (504.0) and Pu Yin old green tea.
Teachers and students from the Department of Stomatology of Zhejiang Medical University investigated the incidence of dental caries, fluoride content in drinking water sources and drinking habits of residents in tea areas around Longjing, Hangzhou. The results show that drinking tea really improves the ability and resistance of tooth caries prevention. For example, the average fluorine content of drinking water sources in Longjingcha area of Hangzhou is 0. 1 1ppm, the incidence of dental caries is 72. 12%, and the average number of dental caries patients is 4.2. However, the average fluorine content of drinking water source in Shibanqiao Township, Linxian County, Henan Province is OPPm, and the incidence of dental caries is as high as 92.4%, with an average of 9.6 dental caries. The fluorine content of drinking water sources in the two places is almost the same, but there are significant differences in the incidence, number and number of dental caries. This difference may be related to other factors, but it certainly has a lot to do with drinking tea, because more than half of the people in Longjing tea area have the habit of drinking tea, which makes up for the shortage of the actual intake rate and quantity of some fluorine, while more than half of the people in Shiban Township of Linxian County have the habit of drinking tea. Therefore, although the fluoride content of drinking water sources is the same, the incidence of dental caries in the two places is obviously different.
4. Improve the fluorine content in drinking water: The fluorine in human body mainly comes from drinking water, so the strength of a person's caries prevention ability is closely related to the fluorine content in local drinking water sources. It is generally considered that the fluorine content of drinking water source is 0.7 ~ 1.0 ppm. But in fact, the fluorine content in most parts of China, especially in the densely populated southern water sources, often fails to meet this standard. Therefore, the incidence of dental caries is generally high, about 60% in many areas, 70% ~ 80% in some areas, and more than 90% in some areas with low fluoride. Therefore, at present, fluoride is added to tap water to improve residents' caries prevention ability.
[treatment prescription] 1. Ginkgo biloba; Treat tooth decay. Raw Ginkgo biloba (Ginkgo biloba), chew 1 after every meal.
2. Zanthoxylum bungeanum wine: cure toothache caused by wind insects. Soak soju in pepper and rinse it frequently.
3. The aged tomato sauce can cure the pain of dental caries and apply it to the pain at the end.
4. Luffa: used to treat toothache caused by wind insects. It is scalded with frosted Luffa, so the end is rubbed locally.
5. 1 bowl of banana juice, rinse your mouth after frying, which can cure dental caries pain. You can also eat more bananas.
6. Eat duck eggs: it has a slight effect of stopping dental caries.
7.4 ounces of aged vinegar and 6 grams of pepper. Decoct in water, remove pepper and wash. It can cure toothache.
