"Dirty" in medicine is generally defined by the number of bacteria. Many parts seem as white as snow and "harmless to humans and animals", but in fact they hide dirt and hold dirt, just like a natural bacterial culture dish.
One of the four most "dirty" places in the human body is the mouth we use to eat.
"Disease enters the mouth": The oral cavity is one of the main ways bacteria, viruses, fungi and other foreign antigens enter the human body. This part of the free foreign bacteria mainly exists in saliva, and there are also a large number of endogenous microorganisms. Colonies, parasitize the oral cavity, teeth and mucosal surfaces in the form of colonies. Exogenous and endogenous microorganisms, the number of bacteria mixed in the oral cavity is really countless, the types are quite diverse, there are pathogenic bacteria, non-pathogenic bacteria, and conditional pathogenic bacteria. There are at least 700 kinds of bacteria, hundreds of billions of them.
What happens if you don't brush your teeth a day?
For contemporary young people who pay special attention to appearance, the bath must be washed every day, but the teeth need not be brushed.
Many young people suffer from procrastination when it comes to brushing their teeth. There are countless people who only brush their teeth once a day. As everyone knows, your lazy brushing today is the sin of seeing your teeth tomorrow.
Suppose you just finished eating and decided not to brush your teeth:
3 hours later, the food residue in the teeth began to ferment and successfully cultivated the first batch of bacteria;
4 hours later, the elders of the bacteria settled on the tooth surface, the tooth surface film Provide them with nutrition, including food and housing. Since
has not brushed teeth for a long time, bacteria lack natural enemies. As a result, they began to "make gangs and fall in love, marry wives and children to make villains" . At this stage, bacteria only do one thing: reproduction. Z2z
12 hours later, the ruthless reproduction machine- bacteria formed a huge flora and dental plaque was born. At the same time, the carbohydrates left in the mouth will ferment to produce lactic acid and other substances, which will slowly corrode tooth enamel.
There are about 200 billion bacteria per gram of dental plaque, which is more dirty than a toilet that has been used for 10 years.
15 hours later, the calcium in the saliva and the dental plaque on the surface of the teeth went together instantly, giving birth to the "calculi" of love-dental calculus.
Dental calculus is mainly attached to the root and surface of the tooth. It will make the tooth yellow and lose its original luster.
After 3 months, the calculus has become calcified and hard, and it is too late to try to save it by brushing my teeth.
After 6 months, the gums became soft, red, swollen and bleeding under the persecution of dental calculus.
Do you know this knowledge about oral health?

Oral health directly or indirectly affects the health of the whole body and is an important part of the health of the whole body.

60-90% of school-age children and nearly 100% of adults worldwide suffer from dental caries; 15-20% of middle-aged people (35-44 years old) suffer from severe periodontal disease, which may cause tooth loss; about 30% of people aged 65-74 have no natural teeth. Z2z
Cleaning the oral cavity is very important. Brushing, rinsing, flossing
diet and bacteria are the most important factors leading to dental caries and periodontal diseases. Therefore, removing dental plaque is the basis for maintaining oral health. Brushing can remove dental plaque, soft dirt and food residues, maintain oral hygiene, and maintain the health of teeth and periodontal tissues.
After brushing your teeth for several hours, the plaque can reattach to the clean tooth surface and continue to form. Especially after falling asleep at night, the secretion of saliva is reduced, the self-cleaning effect of the mouth is poor, and bacteria are more likely to grow. Therefore, brush your teeth at least twice a day, and it is more important to brush your teeth at night before going to bed. It is recommended to use the horizontal vibrating brushing method to brush your teeth. The bristles of the toothbrush cannot fully extend to the gap between the teeth when brushing. If you can use dental floss or interdental brush to help clean the gap between teeth after brushing your teeth every day, you can achieve the purpose of thoroughly cleaning the teeth. Chewing sugar-free gum can also stimulate saliva secretion, reduce oral acidity, help fresh breath and clean teeth.
