Everyone knows that teething in a child is a lot of trouble. Replacing milk teeth with permanent ones also has its own characteristics. It is necessary that the molars grow even and beautiful. To do this, it is necessary to pay attention to the development of children's teeth - whether the milk teeth were replaced with permanent ones on time. To distinguish a milk tooth from a permanent one should not only a dentist and an orthodontist, but also mothers and fathers.
Instructions
Step 1
The first teeth appear in a child from about 6 months, and by the age of three, teeth in the baby's mouth are already 20. Milk teeth got their name from the father of medicine Hippocrates, who saw the connection between the first teeth of the child and the period of breastfeeding. Milk teeth fully mature by the age of 5 and are used temporarily - for several years, until they are replaced by permanent ones.
Step 2
At the age of 6-8, the child has the first permanent teeth. These are usually large molars. It turns out that a 6-year-old child has milk teeth in the front of his mouth, and in the depths, permanent ones grow. The change of teeth, when milk teeth fall out and permanent ones grow in their place, occurs after 6-8 years. However, it should be noted right away that changing teeth is an individual matter, there are no clear terms here.
Step 3
Milk and permanent teeth have many differences. Milk teeth are temporary teeth. They fall out under the influence of three buoyancy forces. First, the roots grow inside the tooth for the future permanent tooth and squeeze the tooth through the canals. Secondly, the permanent tooth rises up and rests against the milk one. Thirdly, the roots of the milk tooth are destroyed by special cells, osteoclasts, and the milk tooth remains without adhesion to the jaw. It turns out that the root of the milk tooth is eaten up - it becomes very thin and long in relation to the crown. This is why it is very easy to remove such a tooth.
Step 4
The molars differ in their number. In an adult, there are usually 32 of them. The roots of the permanent teeth strongly diverge and bend. You can distinguish milk teeth from permanent ones by their shape. A milk tooth has a cushion-like thickening of the tooth enamel in the cervical portion of the tooth. In milk teeth, the longitudinal axis of the crowns is inclined towards the palate and tongue. This palatal (lingual) slope gives out the milk teeth among the permanent ones.
Step 5
You can distinguish between milk and permanent teeth by color. Dairy is usually uniform white with a slight bluish tinge. The molars are always yellowish or grayish in color, and the necks of the teeth are darker. And the last sign of a milk tooth: it is not as hard as a permanent tooth. As a rule, baby teeth are easier to drill in the dentist's office.
