"Eat well": A good bite of teeth is the key

For many years, the theme of the National Love Teeth Day has revolved around the theme of "oral health, whole body health", with the aim of enhancing the oral health literacy of the whole people and creating a social public opinion atmosphere
conducive to oral health 。 The Action Plan for Healthy Oral Care (2019-2025) clearly requires that by 2020, the oral health service system will be basically sound, the overall oral health service capacity will be improved, and the oral health care level of key groups such as children and the elderly will steadily increase; By 2025, a supportive environment for a healthy oral society will be basically formed, the oral health literacy level and health behavior of the population will increase significantly, and oral health services will cover the whole population and the whole life cycle, so as to better meet the health needs of
the people.

Oral health is the cornerstone of whole-body health

"Undoubtedly, good oral health is an important cornerstone of overall health, making our three meals a day taste and ensuring reliable life
and health.
" Recently, in a popular science class on the protection of oral health, Professor Feng Cambridge, an expert of Chinese food think tank, president of the Northeast Branch of the Contemporary Stomatology Association, director of the Heilongjiang Branch of the Stomatology Committee of the Chinese Medical Association, master tutor of the First Affiliated Hospital of Harbin Medical University, and professor of the Department of Prosthodontics, said
.

Feng Cambridge said that oral health has long been listed by the World Health Organization (WHO) as one of the ten major standards of human health, the specific content of which is clean teeth, no cavities, no pain, normal gum color, no bleeding; At the same time, there is no chronic oral and maxillofacial pain, oropharyngeal cancer, mouth ulcers, congenital defects such as cleft lip and palate
.
At the same time, the WHO also gives a set of figures for dental health: "8020", that is, 80-year-old people should have at least 20 functional teeth (teeth that can chew food normally and do not loosen), aiming to extend the life of teeth as much as possible to ensure health and improve the quality
of life.

At the same time, the WHO also clearly regards oral diseases as a serious public health problem, and proposes to increase efforts to actively prevent and treat them
.
Feng Cambridge explained that oral diseases such as caries, periodontal disease, endodontic disease, etc.
can easily destroy the hard tissue of teeth and the supporting tissues around the teeth, in addition to interfering with functions such as chewing, speech, and aesthetics, they can also lead to social communication difficulties and psychological disorders
。 Some microorganisms exist in the mouth for a long time, which can cause or aggravate certain diseases such as coronary heart disease, diabetes, lung infection, chronic gastritis, gastric ulcer, kidney disease, etc.
; The harm of systemic diseases to oral health cannot be ignored, for example, diabetic patients have reduced ability to resist infection, often accompanied by periodontitis, difficult to heal tooth extraction wounds, and increased failure rate of dental implants.
AIDS patients have oral lesions in the early stage, such as oral candidiasis, hairy leukoplakia, etc.
; Oral infections in pregnant women are also a risk factor
for preterm birth and low birth weight.

Improper eating and bad habits are harmful

Taking dental caries as an example, this is because the mouth is unclean and infected with a certain chain lytic bacteria, so that the sugar in the food becomes polysaccharide nucleic acid, dissolves the enamel of the teeth, and then produces a disease of decalcification and decay, which is also called tooth decay or insect teeth
.
Feng Cambridge introduced that eating sugar itself helps the activity of lactobacilli in the mouth, which can decompose sugar foods to produce acids, which are easy to induce dental
caries.
Eating sugar for a long time or too much will remove more minerals from the surface of the teeth, and it is also easy to breed oral bacteria and shake the foundation of
oral health.

In addition, carbonated drinks also have a very large effect on tooth damage, because the pH value of carbonated drinks is relatively low and acidic, which can cause erosion to teeth and form acid erosion
.
People who drink carbonated drinks for a long time will gradually lose bone calcium, loosen tooth bone, and the hard tissue of the tooth body will become thin, transparent, sparse, and very sensitive to any external stimulation; People who like to drink a lot of carbonated drinks will also produce a long-lasting acidic environment in the mouth, which is harmful to the mouth
.
Carbonated drinks also contain polyphosphate, which will drag down the body's absorption and utilization of calcium and phosphorus, and the chance of tooth decay is
multiplied.
In the long run, a series of demineralized spots will condense on the surface of the teeth, which are difficult to repair by the body and can only be remedied
by professional doctors.

Learn to brush your teeth properly and check your mouth regularly

Clinically, oral diseases are preventable, controllable and treatable
.
Von Cambridge said that caries and periodontal disease are bacterial infectious diseases, and the bacteria of dental plaque and its products are the "culprits" that cause caries and periodontal disease, and caries and periodontal disease
do not occur without plaque microorganisms.
The prevention and control of oral diseases requires a combination of personal oral maintenance and professional maintenance, including effective brushing, balanced diet, rational use of fluoride, regular oral examination, etc.
; Professional oral maintenance includes topical fluoride, pit and fissure sealing, and cleaning (scaling).

Feng Cambridge pointed out that effective brushing can remove plaque and is the most important personal oral maintenance measure
.
The internationally recognized modified pasteur brushing method, also known as gingival sulcus sweeping or horizontal fibrillation, is an effective method of removing plaque near the gingival margin and in the gingival sulcus, emphasizing that brushing is comprehensive, helping to remove plaque at the gum edge and between the teeth, at least 2 minutes at a time, while children's brushing methods mainly include arc method and brushing method
。 Feng Cambridge introduced that if it is a baby of about 6 months, the first baby tooth may just begin to erupt, parents can use finger toothbrushes or gauze made of finger sleeves, dipped in warm boiled water to help children clean their teeth; In children after the age of 1, 8 baby teeth may have erupted, and there are 4 upper and lower teeth, and parents can use the baby's toothbrush to dip the toothpaste to help the child brush his teeth
.

If it is a child over 3 years old, the behavioral ability has been significantly improved, at this time, parents can guide the child to brush his teeth by himself, and cultivating good habits of brushing teeth in young children and children is sometimes more important
than specific operations.
In daily life, it is especially recommended to let children of this age brush their teeth with the arc method, that is, brush their teeth by drawing circles on the teeth with a toothbrush, which can achieve a good cleaning effect
.
If you are a school-age child, such as a child after primary school, you can brush your teeth with a brushing method, that is, brush your teeth
by vibrating horizontally.

Both adults and children must brush their teeth every day, preferably once a day in the morning and evening, and 20 minutes after meals
.
Von Cambridge also recommends that adults have oral exams by professional doctors every six months or a year, and children have oral exams
every three months to six months.
For children with a tendency to caries, it is recommended to do pit and fissure sealing treatment as soon as possible to avoid food residue trapped in the
tooth groove.

Avoid the harm of adverse factors to teeth

In daily life, how to avoid adverse risk factors and ensure oral health? Feng Cambridge reminded that not brushing your teeth before going to bed is the most harmful to oral health; Secondly, smoking, snacks and carbonated drinks are also lurking hidden dangers, which must be eliminated in order to fundamentally maintain a good oral environment
.

At the same time, usually eat more calcium-containing foods and fresh fruits and vegetables
.
Feng Cambridge explained that if there is a lack of calcium in the body, the teeth will become sparse and easily induce caries
.
Vitamin D has the function of promoting the absorption of calcium and phosphorus, and vitamin A also has the effect of increasing the antibacterial effect of the gum mucosa, so it is necessary to ensure the supply
from the diet.
Fish and rice, lentils, peas, broad beans and other foods are high in phosphorus, and phosphate can form a buffer system to prevent excessive acidification
of the mouth.
It is recommended that everyone, especially children, eat more calcium-rich foods such as beans, soy products, dairy products, fish, shrimp, and rib soup to provide enough protein, minerals and vitamins to make teeth develop
normally.

Similarly, fresh fruits and vegetables contain a lot of mineral elements such as calcium and phosphorus and sufficient vitamins, which have many benefits
to the body.
Fruits and vegetables can also help promote calcification of tooth tissue, increase tooth hardness, and enhance resistance to acidic harmful substances
.
Fruits such as apples, raw pears, etc.
can be mechanically scrubbed to wipe away bacteria adhering to the surface of teeth when eating; And vegetable fiber also has the effect of mechanical friction cleaning and stimulating the secretion of salivary glands, which can effectively clean the surface of teeth and avoid the adhesion of food and the attachment
of plaque.

The "Tooth Swallowing Health Care Method" may as well give it a try

"If you have strong teeth, you will be healthy, and if you are healthy, you will live a long life"
.
Finally, Feng Cambridge also recommended a traditional Chinese medicine "percussion and swallowing jin health care method" for citizens, the specific operation essentials are: wake up in the morning, relax physically and mentally, abandon distractions, close your mouth and eyes, lightly press the tip of your tongue against the upper palate, and then let the upper and lower teeth tap each other rhythmically, as the exercise progresses, you can gradually increase the number and strength of percussion, usually 30-300 times
.
The strength can be measured
according to the health of the teeth.
You can also do it once in the morning after getting up, after lunch, and before going to bed, about 3 minutes each time, standing and sitting
.

Feng Cambridge explained that the vibration caused by percussion stimulates the pulp and gums, strengthens the teeth and periodontal tissue, stimulates dental nerves, cells and blood vessels, promotes blood circulation in the tooth body and periodontal, improves the nutritional supply of teeth, increases periodontal disease resistance and regeneration, and the resistance of the tooth itself, making the teeth harder and more stable, which is beneficial to oral health
.
Regular percussion can also make the perioral muscles maintain and enhance solid organic energy, and maintain a certain fullness, which is also beneficial to delay the aging of facial skin
.

Tapping is followed by a swallowing motion, that is, using your tongue to rotate along the inside and outside of the upper and lower teeth, and slowly swallowing saliva
.
The so-called "jin" is the saliva secreted by oral activity, which can maintain the cleanliness of the mouth, help to soak and soften food, and facilitate swallowing and digestion
.
Modern medical research has confirmed that saliva contains immunoglobulins, amino acids, various enzymes and vitamins, which can participate in the body's metabolism and growth and development, and enhance immune function
.

In addition, massaging the gums is also a good method, it is very simple to use the thumb and index finger to massage the gums in a certain direction for 10 minutes each time, this method can promote blood circulation in the gums, alveolar and pulp, and prevent premature gum recession
.

What are the benefits of regular "teeth cleaning"?

Scaling can clean the mouth, maintain oral cleanliness, and timely detect adverse oral changes such as dental caries, and treat them early to avoid further development
of lesions.
At the same time, it can also detect bad restorations in time, re-do treatment in time, and prevent the formation
of periodontal disease.
In addition, it can also prevent bad
breath to a certain extent.
Because periodontitis and periodontal disease are risk factors for subacute endocarditis, diabetes and respiratory diseases, it is recommended to clean your teeth regularly and maintain oral hygiene, which can prevent such diseases
to a certain extent.

It is generally recommended to have an oral examination 1 to 2 times a year, and it is enough
to perform teeth cleaning at the same time as the oral examination.

What foods contribute to oral health in your daily life?

1.
Celery
.
Celery contains a lot of crude fiber, which can clean away food debris on the teeth, and chewing celery often can stimulate oral saliva to achieve antibacterial effect
.

2.
Cheese
.
The calcium contained in cheese can balance the pH of the mouth, effectively prevent the survival of bacteria in the mouth, and avoid the formation
of tooth decay.

3.
Green tea
.
Green tea contains a lot of fluorine, which has the effect of preventing tooth decay, and the tea polyphenols in green tea can clean the breath and avoid the occurrence
of bad breath.

4.
Onion
.
Onions are a bactericidal food that effectively kills bacteria in the mouth and prevents tooth decay
.
