2, if the circumstances are serious, it is recommended to go to the Department of Stomatology for medical diagnosis.
3. Develop good oral hygiene habits.
There are many reasons for food blockage.
1, adjacent teeth have dental caries. Solve it by filling teeth.
2. Abnormal tooth position arrangement (such as impaction and dislocation). ). Need tooth extraction and orthodontic treatment.
Tooth is a kind of structure existing in many animals, and it is an organ for human, amphibians, reptiles, birds and higher mammals to chew food. Teeth are the hardest organs in the human body. Generally speaking, teeth are white (slightly yellow for normal people) and hard in texture. Teeth of various shapes are suitable for many purposes, including tearing and grinding food. Teeth are natural self-defense weapons for animals. The pronunciation of human language is closely related to the upper and lower teeth (front teeth) in the oral cavity, which is called "Ya Yan" in the standard language of ancient Han nationality. The regularity of teeth is even related to social activities and status.
There is a certain relationship between the growth of teeth and bones, but the growth of teeth and bones is not completely parallel because of the different origins of embryos. At birth, the deciduous teeth have been ossified, and the tooth spores of the deciduous teeth are hidden in the jaw and covered by gums; The ossification of permanent teeth began in neonatal period, and the ossification of the third permanent molar began at 18 ~ 24 months old. People have two sets of teeth: deciduous teeth (20 * * *) and permanent teeth (28 ~ 32). Primary teeth begin to erupt at 4 ~ 10 months after birth, and those who do not erupt after 12 months delay their eruption. The eruption sequence of deciduous teeth is generally mandible before maxilla, from front to back, deciduous teeth erupt at about 2.5 years old. The eruption time of deciduous teeth varies greatly among individuals, which is related to genetic, endocrine and food traits.
The first permanent tooth (the first permanent molar, followed by the second deciduous molar, also known as the six-year-old tooth) erupted around the age of 6; 6 ~ 12 years old, deciduous teeth were replaced by permanent teeth in the same position, 1 and 2 premolars were replaced 1 and 2 deciduous teeth, which was a mixed dentition period; The eruption age of the second permanent molar12; The third permanent molar (wisdom tooth) will erupt after 18 years old, and some people will not erupt for life.
Teething is a physiological phenomenon. When teething, some babies will have symptoms such as low fever, increased saliva, salivation, restless sleep and irritability. The healthy growth of teeth is related to protein, calcium, phosphorus, fluorine, vitamins A, C, D and thyroid hormone. Chewing food is good for tooth growth. When teeth grow abnormally, diseases such as ectodermal dysplasia, calcium or fluoride deficiency and hypothyroidism can be seen.
