1. Prevent dental caries and periodontal disease. Dental caries is commonly known as tooth decay. Its pathogenic factors include microorganisms (bacteria and plaque), diet and host teeth (teeth, saliva).
Three major health factors and prevention methods:
1. Brush your teeth correctly to prevent bacteria and dental plaque.
Pay attention to diet, eat more fiber food and less sugar. Sugar in food, especially sucrose, has the most obvious cariogenic effect. Such as cakes, biscuits, cheese, etc. It is easy to stick to the surface of teeth, ferment and produce acid, and promote the occurrence of dental caries. Fiber foods, such as vegetables and coarse grains, have mechanical friction on the tooth surface, which can clean the tooth surface and prevent dental caries to some extent. Protein and fatty foods can enhance the formation of enamel and reduce the ability to resist caries. In addition, fluoride, calcium and phosphate in food are all raw materials for tooth remineralization. Quantitative fluorine can promote remineralization and enhance acid resistance and antibacterial ability. Magnesium can promote the development and perfection of enamel, and zinc can prevent dental caries from attaching.
3. The shape, position and structure of teeth are closely related to the occurrence of dental caries. Dental caries often occur in the parts where food debris is easy to stay in teeth, such as dental fossa, neck and collar surface. In addition, tooth crowding and dislocation, tooth surface in contact with denture clasp, and the edge of crown that is not tightly sealed are all prone to dental caries. Therefore, it is very important to correct bad teeth in time and clean them thoroughly. Saliva has a self-cleaning effect on the oral cavity and can neutralize acidic products in the oral cavity. The greater the amount of saliva secreted, the less likely dental caries will occur.
2. Correct brushing method
The most effective ways to brush your teeth correctly and clean your mouth are as follows:
1. Horizontal vibration method: the bristles make an angle of 45 with the tooth surface, the bristle head points to the gingival direction and enters the gingival sulcus and adjacent interface area, and some bristles press the gingival edge up and down, and vibrate back and forth for a short distance in the front and back direction. When brushing the lingual side and palatal side of the anterior teeth, it is necessary to erect the toothbrush, press the brush end at 45 degrees, enter the gingival sulcus and the gap between adjacent surfaces, and vibrate up and down. When brushing the occlusal surface, put the bristle head in the into the pit groove and vibrate for a short distance in the front and back direction. This method is effective in removing dental plaque from the neck and adjacent space.
2. Vertical brushing method: place the bristles on the gingival mucosa at an angle of 45, and then rotate them with a toothbrush along the gingival direction and the crown direction. Each part is repeated 8~ 10 times. When brushing the occlusal surface, put the toothbrush on the tooth surface and move it back and forth horizontally.
3. Physiological brushing method: the bristles contact with the tooth surface, point to the crown of the tooth, and then brush your teeth gently along the tooth surface in the direction of the gum, similar to the friction effect of chewing fibrous food on the tooth surface. Suitable for people with healthy periodontal tissue.
Note: In the frequency and time of brushing teeth, we advocate the "three, three, three" brushing method, that is, three times a day, three minutes each time, brushing three sides.
Three. Interdental cleaning
Just general brushing sometimes can't completely clean dental plaque, but dental floss sticks or other oral hygiene AIDS, such as interdental brushes, toothpicks, tongue coating brushes, etc. , should be used.
1. Floss stick: Generally, there are wax-free flosses and fluoride flosses, which can remove food residues, soft scales and dental plaque between teeth.
2. Interdental brush: Interdental brush is suitable for adjacent areas with missing gums, as well as exposed root furcation areas and irregular adjacent surfaces of teeth. In particular, it is more effective than dental floss and toothpicks to remove plaque attached to the neck and root surfaces.
3. Moss brush: The brush surface of the tongue coating brush is made of special soft glue, which can brush off the debris between teeth, especially clean the bacteria accumulated on the tongue surface, keep the breath fresh and keep the mouth healthy.
Note: In the frequency and time of brushing teeth, we advocate the "three, three, three" brushing method, that is, three times a day, three minutes each time, brushing three sides.
Choose a toothbrush
Toothbrush is a necessity in people's life, and everyone should choose a suitable healthy toothbrush according to their age and oral condition.
Brush head: in order to adapt to the situation of oral cavity, the brush head should be small, which is convenient for turnover in oral cavity and cleaning the last part of dentition.
Brush: The brush surface of the toothbrush should be flat, and the force will be the same wherever the toothbrush goes. The bristles should be moderate in hardness and elasticity, so that the bristles are flexible and easy to bend, which is convenient to enter the lower part of the gingival margin and between the teeth, remove some plaque on the adjacent surfaces of the teeth, and remove soft dirt and food residues. There should be a proper distance between the hair bundles to facilitate cleaning and keep the toothbrush dry.
Brush handle: the toothbrush handle is usually in a straight line with the toothbrush head, and the teeth are evenly stressed, which is convenient for vertical brushing, but some special-shaped brush handles are designed with a certain curvature.
Note: The toothbrush head used by children should be smaller, suitable for rotating in the mouth and brushing different areas. The bristles should be thin and soft, with low tuft height and elasticity, which can protect children's tender gums. The brush handle and the brush head are in a straight line, and the shape of the grip is lovely and large, which is beneficial for children to brush their teeth by vibration and circle drawing.
