How many milk teeth should have children
Young parents, faced with the pain of teething first tooth, is wondering how many milk teeth should be in children. All kids are different experience the teething, for some it’s extremely painful, as one almost does not notice. On the emergence and replacement and how much should be milk teeth in a human, read all about it in this article.
When visible teeth
Milk teeth begin to form in the womb at 4-8 weeks of differentiation occurs at 12-14 week process of mineralization goes to 17-18 weeks of pregnancy. Thus, the quality and quantity of the milk teeth in children affects metabolism, toxemia, RH-conflict, endocrine disorders, arthritis, illness of the mother during period of gestation. Negative impact on the fetus cause of anomalies of eruption and development of teeth, hyperplasia, hypoplasia, fluorosis.
Sixteen permanent teeth develop from the fifth month of fetal development, and ends on the 9th month of life. The mineralization of permanent teeth begins in the last weeks of the stay in the womb and continues for nine months. Non-carious lesions of permanent teeth associated with late toxicosis of pregnancy and disease, which had been ill baby.
First teeth appear in babies around the age of six months. When they begin to erupt depends on many factors. It is hereditary and the quality of drinking water, and diet. It is noticed that girls teeth appear a little earlier than boys.
The teething may be accompanied by abundant salivation, the appearance of breath, cough, runny nose, fever up to subfebrile or diarrhea. Parents should understand that this is not normal and complication. So if in 3-4 days diarrhea, or fever persist, then you need to consult a doctor.
The timing of eruption can vary greatly. So, most one-year-old kids can boast of the smile with four teeth, but in the normal range, if the crumbs will be the only one clove. If in the year of the baby is still not even swollen gums, talking about the imminent eruption, then you need to visit the dentist.
A significant advance or delay eruption may indicate pathology of the endocrine system. If the rudiments are absent, the disease is called Edentia.
Erupt as milk teeth
Usually teeth appear in a certain sequence. Appears bottom first (Central) incisor, then his neighbor. After the upper incisors erupt. In the period around the year one can see the lateral incisors, upper first, lower later. And then come the molars (chewing) in 12-15 months, and the fangs in 18-20 months. After about two years noticeable the second molars. Teeth erupt in pairs and with a small time interval.
Why milk teeth
Nature sure has provided, how many milk teeth in children should be to well-formed facial skeleton. They are having a certain structure of roots, let the bones of the jaw and face develop, grow. In addition, they participate in the articulation and important for the health of the digestive system.
Anatomy of the dentition differs significantly from the indigenous:
- because of the size of the jaw the crown is less;
- the roots diverge, since they are the rudiments of the future teeth;
- the enamel is significantly thinner, which makes the tooth more brittle;
- pulp more;
- root channels wide.
The roots of the incisors are fully formed by the age of two to four molars, and the canines only to five.
When a drop of milk teeth
To primary school age starts the process of replacement of milk teeth to permanent. So how does the expansion and growth of the jaw, between the teeth and cause cracks. This is a physiological process and necessary to the molars to give room as they are larger than milk. The bite changes from orthognathic in a straight line. Simultaneously with the appearance of space in milk teeth is the process of resorption of the roots, the circulation stops, the nerves die.
As soon as the milk teeth fall out, they replaced the cut permanent. Sometimes a baby tooth doesn’t want to give «familiar» place indigenous, in this case, you need to go to the doctor and remove it.
Six molars were ready to replace dairy. They gradually push them and cause the destruction of the roots. Resorption of the roots of the tooth can not stay in the bone, becomes mobile and falls out painlessly. But if you did therapy, it is possible to remove healed, the tooth will need the help of a dentist, and anesthesia.
How much a child’s milk teeth
And if the schedule and sequence of growth can vary significantly, and it will be in the normal range, the development index is how many milk teeth in humans erupted for the first three years of life.
On average, in three years the person ends the process of the formation of the milk tooth. Only a child has 20 milk teeth: eight incisors and four molars and canines.
In the normal range, if the teeth are not quite straight, but somewhat to the side. By three years of age, when all the teeth will appear, they will take each its place. Many parents worry that permanent Central and lateral incisors be at a great distance from each other and tilted to the side. But this should not cause concern, because what will happen in the future self-regulation. It is not recommended to intervene in this process so as not to harm the teeth that will erupt after. But to visit as an orthodontist, it is still desirable in the 6 or 7 years, that he considered the individual situation.
When there are molars
Eruption of permanent teeth, unlike milk, does not cause severe pain and discomfort in the child. After deposition on the gums remains an open wound that can be infected with pathogens. It needs to be treated with antiseptic. If the child has a fever, a headache, feel sick, and swollen gums, may have been intoxicated and may need medical help.
10-12 years in your child’s mouth for 28 teeth. All the person has 20 baby teeth and 12 permanent. Wisdom teeth can start to cut and at the age of 20 and 30 and can, for lack of space, not to appear at all. The first permanent teeth is the «six» (rear molars), they are visible already in the fifth year of a child’s life.
To 14 years is the formation of the permanent dentition. Change teeth in the same sequence that erupt. The change of incisors occurs at age 6 to 9 years old, the first molars are replaced by up to 10 years, canines in 10-11, the last give place to a second chewing. How many teeth the child has fallen it is difficult to calculate, as the replacement process continues for eight years, so it may be that fell is less than cut.
Normally, a student must fall as long as all the milk teeth erupted. But as a result of injury or spread of the inflammatory process, the permanent tooth germ may cease to develop. In this case, milk bone formation for a long time do not fall and serve up to the age of majority or even longer.
Why visit a pediatric dentist
To monitor the health of milk teeth is necessary, as the condition of the indigenous. Since children’s enamel is thinner, the faster it is destroyed by bacteria. So they are often affected by caries, it may be pulpitis or periodontitis.
If you do not go to the doctor, the infection can get into the digestive tract and go to the periodontium and the beginnings of permanent teeth. Early removal of milk tooth leads to the development of malocclusion because the following still may not come out exactly where I need, it lacks place, and it can go away. A proper bite is not only a beautiful smile, but also optimal load distribution during chewing, which is necessary for the health of all teeth and directly affects their life.
So how many teeth should be in a child of three years, the answer is: the norm is 20 milk. 4 years erupt the first permanent teeth. In 6 years, the entire milk dentition begins to be replaced by permanent bone formation. For milk teeth very carefully to look as their status depends on the health of permanent teeth and occlusion.
