What kind of toothbrush works well?

Toothbrush is a special tool for cleaning teeth and keeping oral hygiene. If you choose well, brushing your teeth will be completely clean. If you don't choose well, you can't brush your teeth thoroughly and even damage your oral health. Pay attention to the following questions when choosing a toothbrush correctly: (1) Choose a toothbrush according to the users. According to the different oral sizes of adults, children and young children, China's toothbrush standards stipulate the size of the brush head. Adult toothbrushes are larger, children's toothbrushes are smaller and children's toothbrushes are the smallest. The maximum length of brush Mao Mao surface shall not exceed 42mm, the height of bristles shall not exceed 13mm, and the diameter of brush wire shall be 0.2 ~ 0.5 mm. Between 3 mm, these are usually marked on the toothbrush package. If you pay attention to buying a toothbrush, you can buy a toothbrush of the right size. (2) You should buy a toothbrush with a small head. Different types of toothbrushes have different specifications. Brush heads vary in size. If you want to brush the brush head to every part of the mouth, you usually use a small-headed toothbrush. (3) Brushing teeth can avoid stabbing gums. In addition to tooth-shaped toothbrushes, grinding toothbrushes can also effectively achieve the purpose of oral health care. Its outer packaging generally has polished words, and the end faces of the bristles are touched by hand, so there will be no sharp or burr feeling. (4) Pay attention to appearance and price. From the appearance, the products with clean toothbrush, flat bristles and tight packaging are reliable in quality. For those toothbrushes that have no origin and no quality certification, it is not appropriate to buy and use them. (5) The toothbrush shall not be used for more than 3 months. According to the requirements of oral hygiene, the use time of a toothbrush should not exceed 3 months. Perhaps there is no damage to the appearance of the toothbrush after three months of use, but a certain amount of bacteria has been hidden in the bristles, which is not good for oral health care.
