Wisdom teeth
Wisdom teeth often delivers more often us one troubles: in a jaw for them there is no place, they grow crookedly or inflame. Then at swallowing and chewing we suffer from a pain. But whether it is necessary to delete them at once?
At us only 32 teeth: 16 from above, 16 from below, and, accordingly, on 8 from each party. Every eighth tooth is behind a tooth arch is a wisdom tooth. Therefore stomatologists name its “eight”. The majority of people has four wisdom teeth, at many only two, and in some rare cases a wisdom teeth does not develop at all.
Often wisdom teeth and remains grown into bone fabrics, they are not shown over a surface of a gum and are completely not visible. Experts believe, that in 80 % of cases at young men business is so. The Wisdom teeth can appear in a vital interval from 16 till 40 years.
Our ancestors used a wisdom teeth
Wisdom teeth often delivers troubles as they do not have no place in a jaw. This phenomenon is connected with history of development of the person. Millions years ago appearance of our ancestors strongly differed from the modern: the jaw stood out forward more strongly, and the top and bottom tooth arches were longer. On them all 32 teeth well found room. During time the sizes of a jaw were reduced, however the quantity of a teeth remains former. As the wisdom tooth grows the last it just and does not have no place, therefore often the tooth does not break through a gum or grows crookedly.
Complications arise, when:
1. The wisdom tooth grows crookedly or under an inclination.
2. When the wisdom tooth shifts other teeth.
3. When it grows so close to the next tooth, that good clarification of a teeth becomes problematic.
4. When the tooth inflames.
Wisdom teeth is obliged by the name to that fact, that they late enough appear over level of gums. During former times the age associated with wisdom, from here and the name.
As authors of one of articles published in last number JADA (the official publication of the American stomatologic association) consider, necessity of a wisdom teeth for the person is under the big doubt.
If earlier the third molars were necessary to our ancestors for processing of firm food, today to define their role in an organism any more so simply. Especially if to consider, how many troubles they deliver to patients and doctors.
And with the further development of methods of preservation of a teeth the advantage of these teeth will be and is at all doubtful. According to statistical data, 65 % of adult aged people of 20 years have at least one wisdom tooth, and stomatologists annually should spend millions far not the most simple operations on removal of these teeth.
While now in stomatology it is possible to consider as the basic direction of researches cultivation of a new teeth, authors of article believe, that the cited data could be to become a basis for other research aspect – workings out of the methods, allowing to prevent development of a teeth, namely a wisdom teeth. Then large quantity of the problems connected with them, it would be possible to avoid.
