Wisdom teeth when you grow up: up to what age climbs, a growing wisdom tooth

Quite often during a dental appointment, the patient asked the doctor the question is – when they grow molars? This is because in the process of formation of the dentition still in its infancy eight not participating, also after the change of milk teeth to permanent is quite a long time chewing the third molars do not erupt. Knowing that normally a person should be 32 teeth, patients and wonder how many are eight?

Anatomical features

In the course of evolution the human jaw, and with it the row of teeth, has undergone significant changes, a prerequisite of which was the change in the characteristics of food products. After the diet began to dominate annealed, soft products, the size of the jaw in humans gradually decreased by more than 10 mm, and the number of teeth was reduced to 32.

To date, the majority of dentists tend to consider wisdom teeth in the mouth of modern man as vestigial organs. There are a couple of reasons, first of all, reducing the functional load on the third molars. However, when you delete the neighboring eight posterior teeth for one reason or another, prorezalsya wisdom tooth shifting in their place and accept the occlusal load fully. In addition, it can serve as a support for the various orthopedic structures.

When cutting a wisdom tooth? Every person this process is individual and depends not only on the characteristics of its body, but also, to a large extent, from genetic predisposition. Not always grow all 4 eights. There are people who have third molars erupt partially (1 or 2), but there is a category of patients in whom throughout life and do not appear wisdom teeth.

The processes of formation of eights

At what age we should expect the appearance of the third molars? Education the rudiments of eights in the jaw is observed in parallel with the beginning of the change of milk teeth to permanent. This occurs when the child turns 6 years. The process of education in the crown of the third molar is quite long, takes several years and ends at the age of 14-17 years. To grow a wisdom tooth begins only after it is fully formed its crown. But after eight ripping through the mucous membranes of the gums, its roots continue to grow for another 3-4 years.

When can you start to erupt, the last molars? Each person has an age, when there are eight individual and is determined by the peculiarities of his body. The first time they begin to appear after 17 years. Dentists have noted a certain regularity — the third molars grow in pairs, that is, the process occurs simultaneously to the right and left of the same jaw line.

A characteristic feature of the process, when cutting a wisdom tooth, is its considerable length, due to the periodic termination of the growth process. The change of periods of activity and rest are the reason that penetrate the tooth is growing one year, and finally can appear decades later.

Also an ambiguous answer to the question – how long do you grow wisdom teeth. As a rule, their cutting ends to 30 years, however, in dental practice, described clinical cases where the third molars began to erupt from the patient after 40 years.

Signs of teething

When climbing a wisdom tooth, you suffer the symptoms of that process. Specific symptoms due to the fact that third molars have no predecessors in the milk teeth, so when growing a wisdom tooth, he have to pave the way for bone tissue.

If wisdom teeth are coming in, the patient notes the appearance of the following signs:

  • наличиеболевыхощущенийстойсторонылица, grenadinessamoasan;
  • образованиеотекаслизистыхоболочеквобластипрорезывающегосязуба;
  • небольшаяприпухлостьщекисосторонырастущейвосьмерки;
  • увеличениерегионарныхлимфатическихузлов.

At that time, like growing wisdom teeth, and above them formed a kind of pocket of the mucous membranes of the gums. In case of insufficient oral hygiene it can accumulate food debris and bacterial plaque that can cause the development of inflammatory process. In this case, the patient can optionally receive a pathological symptom, as the increase in total body temperature to 37-380.

How much is expressed typical symptoms of the growth process of the third molar, is largely determined by such factors as the availability of free space in the jaw range for unhindered growth of the group of eight, and the situation that initially took her Bud in the bone.

That may hinder the process of teething

Significantly affect the clinical picture and the duration of the process, when a person climb the last molars, can certain anomalies of development of their rudiments in bone:

  • essentialfatty (pozdneeneoliticheskoe);
  • неправильноеанатомическоерасположениевкости (polyclonal, horizontally);
  • излишнеплотныеоболочкизубногомешочка;
  • аномальнаяформазачаткаилиегоразмер.

Such pathological disorders cause not only difficulties of the process of eruption of wisdom tooth. Additionally, the person has excessive crowding of the teeth, which over time leads to destruction of the units, located near the growing tooth, a variety of malocclusion. In some cases, for example, the horizontal placement of the embryo in the bones of the jaw, the third molar does not grow and people are forced to seek specialized help to the dental surgeon for its removal.

An additional difficulty in the growth process of the group of eight is the formation of gingival pockets between its prorezalsya part and the mucosa of the gums. The accumulation in this period of food residues leads to the formation of the inflammatory response, resulting in the patient is experiencing increased pain, impaired chewing function, appearance of an unpleasant smell from the mouth, pus from the pathologic site. Correction of such a violation also holds a dental surgeon, who, after pre-anesthesia carries out the excision of excess mucosa of the gums.

In dental practice, quite often, doctors are faced with such clinical situations, when fully formed wisdom tooth never erupts. Such units must as soon as possible to remove.

This is due to two factors. First, in the case of incomplete formation of the roots of the tooth it is much easier to extract from bones. Second, over time the impacted tooth is not only may be affected by the carious process, but also contributes to the destruction of the roots of the neighbouring teeth, the appearance of inflammation.

What complications can arise

Typically, the process of eruption of the last molars in humans is characterized only by the presence of pain and some difficulty chewing food. These symptoms disappear right after eights will finally cut through the bone. However, in some cases, patients may develop various complications in the process of their growth, some of which pose a real threat not only to health but also human life:

To avoid such complications quite easily. When the first signs of the eruption of wisdom teeth should consult a dentist and spend a radiographic examination of the growing unit. This will help to determine what position is the germ of the tooth and in which direction it grows (up or to the side).

If there are serious anomalies in the formation of the last molars x-ray examination allows timely carry out the necessary remedial measures and to prevent further complications.

Regular preventative dental check-UPS twice a year, provides a constant medical control over the process of eruption and growth of wisdom teeth.
