Toothpaste and toothbrushes, the simpler the better Toothpaste and toothbrushes always occupy several rows of shelves in supermarkets, the variety and efficacy of the full range is overwhelming, and the price difference is great. Brushing teeth is not actually brushing teeth, but brushing plaque bacteria. Therefore, brushing method is the first, brushing apparatus is the second, toothpaste in the third place. Now many toothbrushes in order to pursue sales and improve prices, adding a lot of superimposed features, such as toothbrushes to increase the brush tongue brush, the tongue is the most to brush the root of the tongue, the need for a special brush tongue device, brush tongue brush basically can not reach the root of the tongue. To buy toothbrushes for this gimmick, spend money on the function and can not be achieved. For toothpaste, the main ingredients are mostly the same: abrasives, foaming agents, fragrances and a small amount of drugs. There are 300 to 500 species of plaque bacteria, and it is difficult to kill them with drugs, so the easiest way is to brush them off. Therefore the basic function of a toothbrush is to brush plaque bacteria rather than to treat dental disease. Toothpaste and toothbrushes, the simpler the better and the most economical to use. Toothbrush to choose fine bristles rather than soft bristles Super soft, soft fine, fine bristles …… When buying a toothbrush, many people will be used to looking at the markings on the strength and hardness of the bristles outside the package. Some people will go for soft bristles deliberately because they mistakenly believe that soft bristles do not hurt their teeth. The softness of the bristles is directly proportional to the cleaning efficiency, the softer the bristles, the less clean they are. Almost all toothbrushes use DuPont bristles, so there is little difference. Healthy people should choose a toothbrush with fine bristles because the fine bristles can be cleaned into the crevices of the teeth and the hardness is appropriate. People with doctor-diagnosed gum recession need to choose a soft-bristled one. Brushing your teeth at night is more important than brushing in the morning Brushing your teeth once in the morning and once in the evening is more important. Plaque bacteria are anaerobic, which means they grow in anaerobic conditions. When you sleep at night, your mouth is closed and saliva production in your mouth is reduced, creating an anaerobic environment suitable for the growth of anaerobic bacteria. In fact, the reproduction cycle of dental plaque bacteria is also at night. Once this is understood, you will know that brushing at night is actually more important than brushing in the morning, and brushing at night can remove the plaque bacteria that have the ability to reproduce.

The standard toothpick should be triangular It is the habit of many people to floss with toothpicks or dental floss after eating, which is not a good habit because currently there are no dental standard toothpicks or dental floss that can be bought on the market. The toothpicks available on the market now are cylindrical with a thick bottom and pointed top. The dental standard toothpicks are triangular in cross-section, and this shape coincides with the inverted triangular gap between the roots of the teeth, which can effectively remove plaque bacteria between the teeth and gums. You should not brush your teeth after eating sugar but rinse your mouth. Many people know that cane sugar can corrode teeth, so they consciously brush their teeth after eating sweets. This is a big mistake. He introduced, the oral cavity of Streptococcus pyogenes in the decomposition of sucrose will produce tooth-corrosive acid, and saliva in the calcium can be this acid corrosion of the teeth to repair up, after eating sweets brush teeth will make this automatic repair ability disappear. Therefore, you cannot brush your teeth after eating sweets, but you should rinse your mouth. Rinsing your mouth can dilute this acid and will not destroy the self-repair function of your mouth.
