Chinese people know how to eat and love to eat more. China’s sugar consumption continued to grow at a high speed at an annual growth rate of 6.2%. At present, China’s per capita sugar consumption has reached 10kg; The annual growth rate of carbonated drinks is 10%. In addition to three meals a day, the number of times that modern people eat extra meals, eat snacks and drinks every day is also increasing. Chinese urban residents are entering the “multi meal era”.
According to the oral health survey of urban residents conducted by the Chinese Stomatological Association this year, about 70% of the residents in the four major cities of Beijing, Shanghai and Guangcheng have the habit of eating snacks or drinks outside their three meals, and more than 15% of the residents even have seven meals a day; Among them, children’s average daily eating frequency is higher than that of adults. In the era of multiple meals, frequent eating and drinking will lead to higher oral risk. Therefore, timely oral care after each meal is very important to maintain dental health.

dentists recommend 4 good habits of loving teeth
One of the good habits of loving teeth – brush your teeth with fluoride toothpaste in the morning and evening
Brushing teeth can remove dental plaque, soft dirt and food residues, maintain oral hygiene, and maintain the health of teeth and periodontal tissues.
It is recommended to brush your teeth with fluoride toothpaste in the morning and evening, with each brushing time not less than 3 minutes.
The second good habit of loving teeth — keeping a balanced diet
Reasonable diet and nutrition are very important to maintain oral health.
The food composition in the daily diet should be diversified to ensure the intake of trace elements.
At the same time, reducing the intake of sweets and carbonated drinks can reduce the occurrence of caries.
The third good habit of loving teeth — chewing sugar free gum after eating and drinking
After meals, food residues remain on the surface of teeth, and the acidity of the mouth rises, which is easy to increase the risk of dental caries.
Chewing sugar free gum can promote saliva secretion, neutralize oral acidity, and help clean food residues and reduce the risk of dental caries.
The sweetness in sugar free chewing gum comes from sugar substitutes such as xylitol and sorbitol. Xylitol and other sweeteners are not metabolized by bacteria in the mouth to produce acids, so they will not lead to tooth decay.
The fourth good habit of loving teeth – regular oral examination
Regular examination can find the cavities that have occurred and treat them in time.
At the same time, it can find hidden dangers of tooth decay in time to avoid tooth decay.
