For a long time, we have despised oral hygiene, not to mention the vast rural areas. Even urban residents do not pay attention to oral hygiene. Even the most knowledgeable college students in colleges and universities have not developed the habit of brushing their teeth in the morning and evening, let alone oral health care such as "tooth washing". According to the second national oral health epidemiological survey, the prevalence rate of permanent teeth in China is nearly 50%, and the average number of missing teeth of the elderly aged 65-74 is as high as 1 1. According to statistics, China has less than/kloc-0 dentists per 50,000 people, while Sweden has/kloc-0 dentists per 800 people on average. To reduce common oral diseases, we should not only cultivate civilized living habits, but also pay attention to daily oral health care. In developed countries, people pay as much attention to dental care as to other organs of the body. For example, due to careless oral hygiene or incorrect brushing methods, a large amount of dental plaque will accumulate on the tooth surface, especially the parts that the toothbrush can't "take care of", which will turn into dental calculus over time and press the gums back. Once dental calculus is formed, brushing your teeth is impossible to remove. Therefore, adults should often "wash their teeth" to remove dental plaque and calculus, so as to strengthen periodontal protection and ensure gum health. Otherwise, inflammation will gradually erode alveolar bone, cause periodontal disease, lead to periodontal atrophy, loose teeth, and finally teeth fall off.
China used to say "smile without showing one's teeth", which is considered as a kind of beauty. In fact, many people have bad teeth. With the improvement of civilization, people will have various requirements for oral health care, hoping to have healthy teeth and make themselves laugh more confidently.
In our country's folk proverb, there is "cold water to wash your face, beauty care;" Brush your teeth with warm water to strengthen your teeth; Soaking feet in hot water is better than taking tonic.
Brushing your teeth with warm water will remove bacteria and food residues from your teeth, thus protecting and cleaning your teeth and reducing diseases. Japanese medical experts' research on tooth ecology shows that the suitable temperature for brushing teeth is 35-36 degrees Celsius. Too hot or too cold water can irritate teeth and gums, cause bleeding and spasm of gums, and even lead to periodontitis, gingivitis and oral ulcer.
The role of hot water soaking feet is even greater. Cold feet will slow down nasopharyngeal activities, leading to a decline in disease prevention.
