Numbering of teeth in dentistry

Only at first glance, the teeth of a man seem to be similar to each other. In fact, each of the teeth has an individual configuration that has been formed for many millennia, and which ideally corresponds to the performance of a particular function. The different structure of human teeth is explained by their purpose: with one teeth we bite off food (incisors and fangs), others we chew on it (chewing teeth). And the teeth have the property to hurt, and when we come to the dentist, either we explain for a long time and confusingly what kind of tooth requires treatment, or the dentist himself discovers "sick" by tapping a mirror on all the teeth in succession: on what tooth the patient made a scream, The one and the right one.

However, the dentist can alleviate the fate, specifically calling the sick tooth. After all, you probably heard how the dentists call them "six", "eight", etc. In dental medicine, a certain numbering of teeth is adopted. Their count goes from the middle of the dentition to the left and to the right. For example, incisors are the first and second anterior, or frontal, teeth located on both jaws. Their shape is flat, chisel-shaped, which makes it possible to bite off small pieces from a large chunk of food without problems. For the same purpose, conical fangs are also called "troikas". With their help you can tear off and even bite off more dense pieces.

The function of all other teeth is chewing food, i.e. Grinding it to a state favorable for the normal process of digestion. Since each tooth has its own specific function, it is also designed for its part of the load, so when it is removed, the load that it carries is left to the remaining teeth. This can lead to deformation. To prevent this, you need to replace the removed tooth with a prosthesis as soon as possible.

But back to the topic. The numbering of human teeth continues as follows: the "quartet" and the "five" are called small chewing teeth, or premolars. Large chewing teeth, or molars - are "six", "seven" and "eight". Sixth teeth are some kind of restraint when closing jaws, resting against each other. The surface of the chewing teeth is not smooth, there are protuberances on it. In premolars, there are two tubercles, and molars - 4-5. The presence of these protrusions contributes to the maximum efficiency of chewing food.

However, the numbering of teeth in dentistry also implies the division of the dentition into segments. There are only four of them, so do not be surprised if you suddenly find out that you do not have a sixth tooth, but forty-sixth, despite the fact that, theoretically, you have them 32. As mentioned above, the numbering of teeth is from the center , Diverge in different directions. Each of these sides is a segment, and the upper right is the "tens", the upper left is the "twenty", the lower left is the "thirty", and the lower right is the "forty". Therefore, for example, the first and second upper teeth on the right, in fact, are 11th and 12th, and the fifth and sixth lower left - 35 and 36.

Those who have "problem" wisdom teeth, probably know that this is the "eight", but the common numbering of teeth shows that his real number, he gets, depending on which segment he sprouted. In other words, the wisdom teeth are numbered 18, 28, 38 and 48. And "dicks", "troikas", etc., teeth are called, more likely, for convenience. So to speak, "names are diminutive."

But in children, the numeration of teeth is much steeper than in adults. The fact is that in the milk teeth the roots are widely spread, which allows them to embrace the rudiment of the future permanent tooth. If you make an x-ray, these rudiments will be visible. Since the permanent teeth are numbered from "ten" to "forty", dairy are considered so: the upper right is "fifty", the upper left - "sixty", the lower left - "seventy", the lower right - "eighty". It is important to remember that if a baby has toothache, they must be treated, despite the fact that they will fall out anyway, because everything that happens with the first teeth has a very strong effect on the further development of permanent teeth.
