1, develop good oral hygiene habits, rinse your mouth after meals and brush your teeth in the morning and evening for 3 minutes at a time.

2. Master the correct brushing method: vertical brushing method should be adopted, that is, the upper teeth are brushed from top to bottom, the lower teeth are brushed from bottom to top, and each face is brushed.

3, the correct choice of toothbrush: brush your teeth with your own toothbrush. You should buy and use health care toothbrushes, and don't brush your teeth with unqualified toothbrushes (such as too hard or too dense bristles). At the same time, we should pay attention to keep the toothbrush clean and intact (for example, the hair of the toothbrush can't fall off), and it is best to replace it once every three months.

4, the correct choice of toothpaste: choose the right toothpaste according to the actual situation of your mouth. Fluoride toothpaste can reduce the incidence of dental caries by 40%, but it is not suitable for children before 3-4 years old and people in high fluoride areas. A certain medicine toothpaste should not be used for a long time.

5, regular oral examination, timely treatment of dental diseases or oral diseases. In early childhood, pit and fissure sealing can effectively prevent dental caries.

6. Don't bite hard objects with your teeth (if you can't open the bottle cap with your teeth, etc.). ).

7, missing teeth, defects should be filled in time. Tooth loss and defect have a certain impact on health. If it can be repaired in time, it can protect the health of teeth and restore normal chewing function. Tooth loss can easily lead to loosening of adjacent teeth, elongation of contralateral teeth and occlusal trauma, and can also cause halitosis, dental caries, periodontal disease and other problems due to food impaction.

8. Develop a good habit of brushing your teeth. Rinse your mouth with warm water after meals and brush your teeth once in the morning and evening. Don't brush your teeth too often, it will damage your teeth, and don't brush your teeth for too long. Pay attention to the correct brushing method: brush vertically along the teeth, first brush the inside and then brush the outside. Don't brush back and forth horizontally, or you will damage your gums.

2 Kindergarten oral health knowledge: How to have healthy teeth?

First, a healthy and complete deciduous dentition is the basis for the health of permanent teeth.

A complete and healthy deciduous dentition can play a normal chewing function, ensure the normal growth and development of permanent teeth and maxillofacial bones, help children pronounce correctly, guide the normal eruption of permanent teeth, and let children get healthy and use permanent teeth for life.

Second, encourage children to eat more fibrous food and enhance chewing function.

A healthy diet structure and good eating habits are the basis of oral health and overall health, and developing good eating habits will benefit children for life. Children should pay attention to a balanced diet, not picky eaters, especially foods with high fiber content and rich nutrition, such as vegetables and fresh fruits. In this way, it is not only beneficial to the self-cleaning function of teeth, but also beneficial to the growth and development of oral and maxillofacial region, promoting the orderly arrangement of teeth and enhancing the chewing function.

Third, don't eat before going to bed after brushing your teeth.

Because people have less oral movement and less saliva secretion during sleep, the self-cleaning effect of the mouth is poor, and eating before going to bed after brushing their teeth is prone to dental caries and gingivitis. In addition, children should develop the habit of eating regularly, and eat as little snacks as possible except for three meals a day. If you often eat snacks, you can add snacks between meals.

Fourth, children learn to brush their teeth, and parents should help and supervise.

At the age of 3-4, children's hands-on ability and coordination ability of limbs are obviously enhanced. Parents can start teaching their children to brush their teeth through the simplest "circle drawing method". The key point is to put the bristles on the tooth surface, gently press and bend the bristles, and draw circles on the tooth surface for more than 5 times. The toothbrush should be placed vertically on the lingual side of the front teeth, and all surfaces of the teeth (including lips, cheeks, tongue and occlusal surfaces) should be brushed. In addition, parents should also help their children brush their teeth/kloc-0 times a day (preferably at night) until their children go to primary school, so as to ensure the effect of brushing their teeth.

Fifth, help children get rid of bad oral habits as soon as possible.

Children's bad oral habits include sucking their fingers, biting their lower lips, sticking out their tongues and breathing through their mouths. We should give up as soon as possible, otherwise it will cause oral and maxillofacial deformities such as maxillary protrusion, dental arch stenosis and crowded dentition. If children over 3 years old still exist

If the above-mentioned bad habits cannot be cured after persuasion, they should be hospitalized in time and help them get rid of bad habits through appropriate correction methods. For children with oral breathing habits, it is necessary to check whether the upper respiratory tract is unobstructed, treat tonsillar enlargement, adenoid hypertrophy, turbinate hypertrophy and other diseases, and correct oral breathing in time.

Six, advocate preschool children to receive an oral health examination every six months.

3~6 years old is the peak period of children's dental caries. At this stage, the dental arch began to change, and gaps appeared between teeth, which prepared for tooth replacement, but it was easy to cause food impaction and adjacent caries. Early treatment of dental caries has the advantages of short time, little pain, good effect and low cost. Therefore, it is suggested that preschool children receive oral health examination once every six months. Doctors should provide targeted professional oral health guidance while conducting oral health examination for children, so as to enhance parents' and children's oral health awareness.

Seven, early correction of anterior teeth "grinding" (anterior teeth occlusion) deformity.

Congenital factors such as maxillary hypoplasia and heredity are the causes of anterior crossbite, and bad feeding posture and children's bad living habits can also cause anterior crossbite. Anterior malocclusion can limit the development of maxilla, lead to excessive protrusion of mandible, and cause depression in the middle of face, which obviously affects the face. Early correction can correct or alleviate facial changes and achieve relatively good therapeutic effects. The best time to correct malocclusion of anterior deciduous teeth is 3~4 years old.

Eight, local use of fluoride to prevent deciduous tooth caries.

Fluorine toothpaste has a positive effect on preventing dental caries. Preschool children usually gargle and spit out foreign bodies in their mouths. Children can brush their teeth with fluoride toothpaste, but the dosage is pea-sized. It should be applied under the supervision and guidance of parents or teachers to prevent accidental swallowing. Don't use adult toothpaste for children. Our annual fluoride foam oral care also reflects the need to prevent and treat dental caries (but the routine treatment should be once every quarter and four times a year).

Nine, deciduous tooth caries should be treated in time.

Dental caries affect children's oral and general health. The initial manifestation of dental caries is local discoloration of the teeth, usually black, and sometimes chalky changes appear in the upper teeth, and then the hard tissue on the tooth surface falls off to form cavities until the teeth completely disintegrate and fall off. Dental caries can cause toothache, swelling of gums and face, and even cause systemic symptoms such as high fever in children. Long-term untreated dental caries can lead to unilateral chewing and asymmetric facial development in children; It will also affect the normal development and eruption of permanent teeth. If there are no healthy teeth, children are unwilling to eat fiber-rich vegetables and meat, resulting in bad eating habits such as partial eclipse and affecting the normal growth and development of the whole body. Therefore, the view that "deciduous teeth always need to be changed, and they need not be treated if they are broken" is wrong.

Ten, timely treatment of deciduous teeth trauma.

Trauma of deciduous teeth mostly occurs in children after 2 years old, mostly front teeth, usually caused by falling. Trauma may lead to tooth loosening, breaking or falling off. Trauma of deciduous teeth may affect the development and normal eruption of permanent teeth in the future, so you should go to a medical institution in time.

3 Kindergarten oral health knowledge: the treatment of children's dental caries

1, drug treatment of dental caries: pit and fissure sealing

This is a method to treat dental caries mainly by prevention, but it still has a certain therapeutic effect on dental caries. Because the pit and fissure sealing technology is to fill polymer resin materials in the decayed pit and fissure of teeth, let the resin penetrate into the cavity, and then solidify and seal it. This can cut off the nutritional source of bacteria in dental caries until the bacteria die; Moreover, pit and fissure sealing method also prevents bacteria from eroding again to some extent.

2. Filling teeth to treat dental caries: glass ion or resin filling teeth.

This method can also treat children's dental caries well. Glass ions have good viscosity with resin materials, little stimulation to dental pulp, insoluble in saliva and similar in color to natural teeth. Just remove the rotten tissue, fill the clean cavity with glass ions or resin, and then polish it after light curing. In particular, resin has plasticity and has enough time to fill and rebuild the shape of teeth.

3. Filling treatment of dental caries: root canal therapy.

Filling therapy refers to removing the diseased tissue of dental caries, preparing it into a cavity with certain retention force, and then filling it with dental materials to restore the original shape of teeth. This is the best way to treat dental caries, especially for children. Root canal therapy is that doctors thoroughly remove infected pulp, infected dentin and toxic decomposition products through root canal therapy equipment, and then fill the cavity after root canal irrigation and disinfection, thus isolating bacteria from entering the root canal and cavity for reinfection, effectively treating dental caries infection and reducing the incidence of inflammation such as periapical periodontitis.

4 Kindergarten oral health knowledge: balanced diet

A balanced diet and proper dietary distribution throughout the day (the key period of tooth growth is 2-6 years old, and in order to make the baby eat snacks as little as possible, four meals a day: breakfast, lunch, dinner and snack time) are very beneficial to strong teeth. At the same time, it is also conducive to our teeth to better resist stimuli: enamel erosion, dental caries ... We should choose more fresh foods in our diet, such as carrots, carrots or apples, which actually play a very good cleaning role when chewing. In addition, lipids, some protein (casein of cheese) and minerals such as phosphorus and calcium can also provide rich nutrition for tooth growth in this age group. Taking Israel CTS Company as an example, its C-Tooth children's toothpaste has introduced dead sea salt children's toothpaste, which is rich in dead sea minerals and can effectively promote tooth growth. In addition, the antibacterial effect of vitamin D can effectively limit the discharge of inorganic salts in enamel.

On the contrary, snacks, especially those "soft" foods, carbohydrate foods (candy or sweet drinks, bread, cakes, etc. ) or acidic foods (soda, fruit, juice) usually increase the risk of dental caries. Sugar can be converted into acid, which may destroy the enamel on the tooth surface. If possible, clean your teeth carefully after every meal. If you don't have the conditions, you can also rinse your mouth seriously or chew a piece of sugar-free gum. In fact, any increase in saliva flow will reduce the risk of dental caries. It should be pointed out that excessive drinking of coffee, tea and smoking may make teeth yellow, so it is more necessary for such people to choose toothpaste with fresh breath and stain removal.

Dairy products make teeth stronger. They are the best source of calcium and phosphorus we need, and they are also the main minerals of tooth enamel and root supporting bone. Mineralization of deciduous teeth began in the fourth month of pregnancy, and mineralization of stone teeth began in the first year of birth. After the teeth are formed, the enamel is renewed and maintained. Drink more milk, and it is best not to drink sweet drinks. Dairy products (yogurt, etc. ) Also bring calcium, phosphorus and vitamin D, which will increase the absorption of calcium and phosphorus. Finally, the main protein casein in milk can limit the excessive discharge of inorganic salts in enamel. People in the past did a good job: they usually ate cheese after dessert and reduced the acid secreted by carbohydrates with the help of casein and lipids in milk.

Drink more mineral water, which is a natural source of fluorine. Natural mineral water meets the human body's demand for fluorine. Fluorine in natural mineral water can increase tooth enamel, strengthen teeth and protect teeth from microbial erosion. Most mineral water contains 0.3 mg of fluorine per liter, but some are as high as 8 mg per liter. Tea, sea fish and some vegetables (spinach, carrots, etc.) also contain fluorine. However, excessive intake of fluoride (more than 2 mg per day) may make teeth black. When we choose children's toothpaste, we should choose fluoride-free toothpaste, especially in the 2- 12 age group, and then use adult toothpaste after 12.

The advantage of using chocolate and sugar-free chewing gum is that cocoa contains tannic acid, fluorine and calcium phosphate. All three substances are involved in protecting teeth. In "sugar-free" chewing gum, sucrose is replaced by sweet polyol, but it will not cause dental caries: xylitol plays a bactericidal role, which is beneficial to reducing dental plaque, and sorbitol (sugar synthesized from glucose or fructose is used as artificial sweetener). Doctor C reminds parents that the baby should chew less gum.
