A survey shows that in China, only 7% of people have the habit of gargling, and most people only gargle when something is stuck in their teeth or when there is a peculiar smell in their mouth. However, it is far from enough to protect oral hygiene by brushing only two or three times a day. This is because if food residues stay in the mouth for too long after eating, they will ferment, breed bacteria, and then stimulate gums and erode teeth. In addition, dental plaque is also closely related to a variety of internal infections and is one of the causes of chronic gastritis, gastric ulcer and other visceral diseases.
Therefore, gargling and brushing teeth are equally important. Professor Takashi nagawa of the health center of Kyoto University in Japan found through research that gargling twice a day for at least 15 seconds can prevent colds, and reduce the probability of catching colds by 40% compared with those who do not gargle.
Compared with the Chinese who do not have the habit of gargling, the Japanese are not vague about gargling and attach great importance to oral health. In public places such as kindergartens and companies in Japan, many people can be seen brushing their teeth even at noon. During the flu season, some Japanese TV stations will call on people to wash their hands and mouth after going out and going home. In particular, after Ebola caused panic in the world, Japanese TV stations began to broadcast preventive measures, which emphasized that people should wash their hands and gargle frequently, and even asked doctors to teach correct gargle methods on the spot: wash their hands before gargling; You must rinse your mouth first and then your throat. If the sequence is wrong, bacteria in your mouth will be carried to your throat, causing infection; When rinsing the mouth, you should hold water in your mouth, bite your back teeth tightly, and use your cheek muscles to make water pass through your teeth and your mouth. Repeat for 2-3 times; It’s best to make a sound when rinsing your throat, and let the water reach the deep part of your throat as far as possible. Repeat the same 2-3 times.
Professor Bi Liangjia, member of the periodontology group of the Chinese Stomatological Association, suggested that gargling with warm water at about 35 ℃ could avoid irritation and reduce the occurrence of pulp inflammation. If you have oral diseases such as periodontitis, you can rinse your mouth with light saline or use medicine mouthwash under the guidance of your doctor. You can often gargle with tea. Tea contains high fluorine, which can promote the remineralization of teeth and effectively prevent cavities. Moreover, tea polyphenols in tea have a strong scavenging effect on free radicals, and also have a certain inhibitory effect on Streptococcus mutans, which causes caries.
