New Year’s Eve is approaching, to enjoy the reunion food and wine, a healthy mouth is essential.
First, oral health needs a “bacteria” team.
The oral cavity is an absolute bacterial environment, there are fungi and bacteria, so as to maintain a relative, dynamic balance. As long as the bacteria are below a certain number, it is normal. There is no absolute harm or benefit to maintain this balance, but only when a certain kind of bacteria overpopulates and breaks this balance, its disadvantages will appear. Of course, tooth decay and periodontal disease both originate from bacterial infection, so let’s learn more about these causative factors next.
There are weak alkaline saliva and food residues in the mouth, which provide suitable conditions for the reproduction of normal flora. There are more than 400 species of bacteria in the human mouth, among which there are harmful bacteria that are detrimental to health, beneficial bacteria that are beneficial to the human body, and conditional pathogenic bacteria in between, i.e. bacteria that cause illness in the human body under certain conditions.
Some researchers have experimentally calculated that in a normal healthy person in 1 gram of tartar can find 10 billion bacteria to, in 1 ml of ordinary saliva can find 80 million Neisseria, in 1 gram of gum secretions can find 1 billion anaerobic streptococcus.
Second, the beneficial bacteria family.
Account for about 1% of the culturable microorganisms in the oral cavity, including Streptococcus salivarius, Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus royi, Lactobacillus swiss, Lactobacillus short, Lactobacillus lactis, Bifidobacterium bifidum, Lactobacillus paracasei, etc.
Third, harmful bacteria family.
It accounts for 99% of culturable microorganisms in the oral cavity, including harmful bacteria Streptococcus mutans (dental caries), Clostridium perfringens (dental caries), Clostridium perfringens (dental caries/pulp and periapical infection), Prevotella intermedia (pulp and periapical infection), Porphyromonas gingivalis (periodontitis/bad breath), Streptococcus oralis (dental caries), Clostridium perfringens (pulp and periapical infection/periodontitis), etc.
IV. Common oral problems.
80% of bad breath is caused by oral problems, with a small percentage coming from the stomach and digestive tract. Modern medicine believes that bad breath is due to the overgrowth of harmful oral bacteria – anaerobic bacteria, decomposition and digestion of food residues, cells, organic matter and blood in the mouth, resulting in volatile sulfides. If you do not develop good brushing habits, for example, you do not like to brush your teeth at night, so that the soft food scales will ferment in the mouth, which in turn causes bad breath. Bad breath problems can also cause periodontal disease if left untreated. Therefore, to adhere to the morning and evening brushing and clean the tongue, then the problem of bad breath will soon be improved.
Fifth, the big gap between the teeth, all because of flossing?
The rumor that flossing will make the gap between your teeth bigger must be debunked today. The so-called large gaps are actually caused by gum recession. As we all know, the leaves on the crown of a tree are very close together, but when you get to the bottom part of the trunk there are gaps. Teeth have the same structure as trees, with roots that are thinner than the crowns. Teeth are grown inside the jawbone by their roots, and when the teeth are healthy, there is no gap between them, but if the gums or the bone tissue of the alveolar bone has a degenerative disease, the roots that should be wrapped by the gums will be exposed, and there will be a gap between the teeth.
As you can see, this gap is caused by gum and bone atrophy, while flossing itself does not hurt the bone or gums and does not cause atrophy. And on the contrary, flossing can prevent periodontitis, such as calculus and toxins secreted by bacteria, thus preventing gum recession.
Sixth, flossing, with or without?
Under normal circumstances, flossing is best used every day. Because the teeth are arranged as one surface, each time you brush your teeth, you can only brush the inner and outer two smooth surfaces, but the gaps between the two teeth cannot be brushed at all. Therefore, flossing should be used to clean the gaps and gums. The normal order of operation is to brush your teeth in the morning and evening, then floss. As you can see, flossing is an important part of the brushing process, do not ignore.
Seven, common oral diseases at different ages.
Under 12 years old: dental caries; 12 to 18 years old: adolescent gingivitis; adults: dental caries/periodontitis; elderly: deciduous/periodontitis.
Tips: teeth need regular checkups, it is recommended that children be checked once every six months and adults once a year.
What types of people are prone to oral diseases?
People with dry mouth, pregnant women, diabetic patients, hypertensive patients (antihypertensive drugs, medication gum growth), and patients with hereditary periodontal disease need to pay extra attention to the prevention of oral diseases.
To maintain oral health, the most important thing you need to do is to brush your teeth in the morning and evening, and adhere to the correct brushing method. Dr. Jie Zhu recommends the BASS brushing method to everyone:.
Eight, BASS brushing method 9 steps.
1. The correct way to hold the toothbrush is to extend the thumb in front of the teeth in a gesture of “zan”.
2, align the toothbrush with the teeth and gums, brush the upper jaw teeth with the bristles facing upward, covering a little gum, the toothbrush for horizontal short distance movement. Brush the lower row of teeth with the bristles facing down, the same as above.
3, Brush bristles and teeth at an angle of 45°～60°, while pressing the bristles lightly toward the teeth, so that the bristles are slightly rounded, and the side of the bristles also have considerable contact with the teeth, but the bristles must not be bifurcated by the teeth.
4.After positioning the toothbrush, start to make a short horizontal movement, brush two or three teeth back and forth about 10 times.
5. Open your mouth wide while brushing to see the last tooth on the right side of the upper row as the best. Next, start from the back right buccal side and brush to the left side; then the left occlusal side, the left lingual side and then back to the right lingual side, and finally the right occlusal side. In this order, you will not miss anything. (There is a recipe for the order of brushing teeth: start on the right side and end on the right side.)
6. When brushing the occlusal surface, also take two teeth as a unit and brush back and forth.
7. The lingual side of the posterior maxillary teeth is a difficult place to brush, so the bristles are still aligned with the junction of the teeth and gums, and the brush handle should be close to the incisors. When brushing the lingual side of the right side, the brush handle will naturally face to the left, at this time we recommend using the left hand to brush the lingual side of the right posterior teeth, which will be much smoother.
8, in addition, brush the buccal side of the back teeth with the same side of the hand, that is, brush the right buccal side with the right hand and the left buccal side with the left hand. At the same time, the brush handle can hold the cheek open to facilitate the line of sight.
9. After brushing the upper teeth, use the same principle and method to brush the lower teeth.
