It turns out to be contagious!

The national oral health epidemiological survey shows that China’s 5-year-old children have an average of more than 4 cavities

September 20th is the 33rd "National Teeth Day"

Let’s see how your teeth were "disappeared" by your brush

If you try hard to brush your teeth every day, how can you still get your teeth broken? That's right! When brushing your teeth in the wrong direction, too much force, it is easy to cause a wedge-shaped tooth defect

A wedge-shaped defect is a defect caused by the slow depletion of hard tissues on the lips and cheeks of the teeth and neck

The main reason for this consequence is to brush vigorously.

In addition, the structure of the tooth neck (the boundary between enamel and cementum) is relatively weak, and the enamel covered is the least, which is easy to be worn away, which contributes to the occurrence of defects; and the acid exudate in the gingival sulcus is also related to the defect

Therefore, in addition to regular oral examinations in daily life, we should also correct brushing methods, avoid horizontal brushing, and choose softer toothbrushes and thinner toothpaste

How to judge that the tooth has been brushed "disappeared"? The degree of wedge-shaped defect of teeth can be divided into the following three types:

Mild: The damage is confined to the enamel or cementum, and there may be mild symptoms of sensitivity.

Medium: The depth of damage is in the middle or deep layer of dentin, and there will be obvious discomfort or excitement pain when encountering stimuli such as cold, hot, sour and sweet

Severe: It can lead to the exposure of the pulp cavity and even the lateral fracture of the teeth.

For severe defects: Root canal treatment is feasible when there is pulp infection or periapical disease; if the defect has caused the tooth to be cross-broken, according to the condition and condition, the overdenture can be removed or after root canal treatment

Is there any cure for congenital deficiency of teeth and calcium supplementation?

The results of the fourth national oral health epidemiological survey showed that the average number of dental caries among adolescents and children aged 3, 4, 5, 12, and 15 were 2 (2.

The prevalence of dental caries in children is very high.

If I find that my teeth are inadequate, can I "rescue" it with calcium supplements? Many parents think that their children’s tooth development is defective and that giving them calcium tablets and vitamin D can make the teeth grow better.

All parts of the teeth are highly mineralized substances, which require many nutrients, such as calcium, phosphorus, fluorine, vitamin B1 and vitamin D, among which calcium is a very important one

However, although the teeth may be further mineralized after eruption, calcium supplementation does little to help tooth calcification

It’s really something to do with heredity.

Indeed, the shape, structure and arrangement of teeth are genetically predisposed
.
The characteristics of the children represent the genes inherited from their parents, and the development of teeth is also regulated by genes
.
The shape, structure and arrangement of the baby's teeth are derived from the genetic inheritance of the parents
.

In addition, the quality of tooth development will also be affected by the maternal environment
.
The development of teeth is a continuous process that begins when the fetus is in the mother's body and continues after birth
.
In the developmental stage of teeth, the mother's poor physical state (such as fever and smoking and other bad habits) can cause irreversible changes in fetal tooth development, including incomplete tooth calcification, hypoplasia of enamel, malocclusion, cleft lip or cleft palate
.

It is worth noting that bad family habits can also lead to the transmission of risk factors for caries, because everyone has bacteria in the mouth
.
At birth, the types of bacteria in the baby's mouth are limited.
With the contact with the surrounding environment as they grow up, the types and numbers of bacteria in the baby's mouth gradually increase
.
Parents have many dental caries, and the cariogenic bacteria in the oral cavity can be passed to the baby through close contact with the baby, and the baby is also prone to dental caries
.
Therefore, parents must avoid feeding bad habits
.

Chairman Ge Lihong of the China Dental Foundation said: Dental caries is a common oral disease in children, which can cause pain, swelling of the gums, and reduced chewing function
.
Develop good tooth brushing habits, it is recommended to use the "arc brushing method"; eat a reasonable diet, rinse mouth with water or tea after eating; it is recommended to seal the pits and fissures of the first permanent molars for children aged 6 to 8, and perform it at the age of 11-13 The second permanent molar pits and fissures are closed; daily use of fluoride toothpaste, half a year for fluoride, etc.
, can effectively prevent dental caries in children and adolescents
.
In addition, it is recommended that children undergo an oral health check every six months to keep abreast of their oral health

The baby should floss too? That's right

First of all, let's take a look at what the role of dental floss is.
In our daily life, there are food residues and soft scales between our teeth, which can be removed with dental floss
.
But the child only has a few teeth, do I need to use it? The answer is yes, as long as the erupted teeth are close together, you need to floss
.

So how to choose the dental floss for the baby? Experts recommend using dental floss picks.
There is not much difference between adult dental floss picks and children’s dental floss picks, except that the children’s dental floss picks are cute in shape and the dental floss is slightly shorter
.

How to floss my baby? When using dental floss, you must have a correct posture.
Just like brushing your teeth, you can use knee-to-knee, embrace, or lie on your mother’s lap.
Your head must be supported and your eyes must be able to see where the dental floss is placed.

.

Reminder: The toothbrush and dental floss can be used together to achieve a comprehensive oral cleaning.
Dental floss should be used at least once a day.
The correct use of dental floss will not damage the teeth and gums

Can mouth sores mean getting angry? "Bane" may be it

Usually, people will habitually regard the long mouth sore as a manifestation of getting angry
.
However, not all oral ulcers are caused by getting angry.
There is also a "curse".
If you don't get your attention, it may become cancerous
.

There are two most common types of oral ulcers: recurrent oral ulcers and traumatic ulcers
.
Recurrent oral ulcer is a localized ulcer disease with repeated occurrence of oral mucosa caused by a variety of factors, which is often said to be caused by getting angry
.
Its incidence is about 20%, ranking first among oral mucosal ulcer diseases
.
Patients often have ulcers that vary in number.
They can heal on their own in more than 7 to 10 days, and they can recur after an intermittent period
.
The length of the interval varies, ranging from a few days to a long period of up to several months
.
But its cause is still unknown
.

Traumatic ulcers are caused by mechanical, such as residual roots, residual crowns, sharp tooth tips, frictional stimulation of poor restorations, chemical stimulation, such as corrosive material stimulation, and oral mucosal damage with a clear etiology caused by thermal stimulation
.
At this time, we must remove the undesirable irritants as soon as possible: remove the residual roots and crowns, sharpen the sharp tooth tips, modify the bad restorations in the oral cavity, and give local medications
.
Otherwise, long-term non-healing may cause cancer in the oral cavity
.

How can we reduce the infestation of mouth sores? According to experts, avoiding rough, hard food and hot food can reduce mucosal trauma
.
In addition, we usually try to achieve a balanced nutrition, a light diet, and eat less grilled, marinated, and spicy foods
.
Maintain regular eating habits, ensure adequate sleep, and improve sleep quality
.
Stay optimistic and avoid anxiety
.
Develop a daily bowel habit
