Wisdom teeth

An adult is usually thirty-two teeth The last four confer wisdom: it is of course the wisdom teeth, those appearing to 17 or 18 years.

The number of teeth may actually be different, because if some people will never have time wisely, others having one, two or three.

Once the teeth have fallen, in childhood, permanent teeth grow gradually. They are more adapted to the solid diet of adults.

There are two dental arches in the mouth, up and down the other. Each is composed of fourteen teeth: two central incisors, while before, then two more side to side.

They are followed by two canines, one on each half-arch, which are more pointed teeth that can "shred" meat, for example. Two premolars and two molars complement the half-arcade. They promote chewing.

For some people, wisdom teeth, otherwise known as third molars, appear in late adolescence. There are two top and two below, if they have a place to grow. The tooth grows in effect from the gum.

The alveolar bone is the origin of each tooth. The base of the tooth is called "Crown". Ligaments and gums maintain it and help push law.

Anomalies

In some cases, their development is disturbed by the lack of space, then they grow partially. Part of the crown only fate, while the other remains in the gum: it says it is retained in the bone.

Sometimes wisdom teeth do not grow or crosswind, causing significant pain and misalignment of other teeth as they jostle them for spot on the arcade.

The abnormal growth mainly wisdom teeth of the lower arcade. These are the ones who most often an abnormal situation in the alveolar bone.

In addition to the pain and the misalignment of teeth, the consequences are numerous. The most common infection of the gums, which occurs around the crown, is the péricoronarite. It occurs on a tooth that is half out of the gum. To curb inflammation, antibiotics and cleaning of the gums are essential.

On the other hand, wisdom teeth are often difficult to achieve through toothbrush. The cavities are very common.

These teeth may also cause damage to the teeth around them, transmitting an infection or tooth decay.

All these reasons extracting wisdom teeth by a dentist.

The operation

It is usually done under local anesthesia in several stages. We remove two teeth and later, the other two. General anesthesia is also possible to remove all four at once.

But the removal of wisdom teeth is less and less. As often removes the premolars in children who begin orthodontic treatment, wisdom teeth then have enough space to grow normally.
