Extraction of wisdom teeth

When they don't have enough room to develop, wisdom teeth can create problems. Sometimes the solution is to remove them. You reassure telling when intervention is recommended and how it performs. Nature is not always perfect. Wisdom teeth often do not have enough space to grow normally. So, when should we remove them? What happens during the operation?

The third molar

Cut, chew, crush ... The teeth are never idle! Incisors, canines, premolars and molars acting in concert. Each arch consists of two central incisors, two lateral incisors, two canines, four premolars and four molars arranged symmetrically. But in some people this cast is completed with the wisdom teeth, which are formed during childhood. Typically, there are four. But it may be only three, two, one or none. Between eight to ten years, the outline of the teeth is visible radiographically. At age 12 the crown is formed. The roots are filled to the 17 or 18 years, which is the average age of eruption. At 25 years, 90% of the wisdom teeth have enough room in the arcade have already appeared. But sometimes these late guests have to struggle to make their way.

What happens when there is a problem?

In some cases the wisdom teeth are within the bone without manifest. But sometimes become infected or are arranged to cause damage to other teeth. This is especially true in wisdom teeth in the jaw, ie the lower arch. In these cases the extraction of wisdom teeth can be considered both for prevent and when a problem arises. This procedure is done for several reasons:

For lack of space

As part of orthodontic treatment when the wisdom teeth have no room. When wisdom teeth are extracted before it is fully formed, we talk about germectomy (extraction of a tooth as a germ). This procedure can be performed from the age of 12 or 14 years. This operation is prescribed after making a panoramic radiograph, an X-ray of both jaws commonly referred panoramic radiography.

Because accidents of evolution

When the tooth eruption does as it should, it can cause several problems: The most common is the inflammation of the tissues surrounding the tooth. This infection occurs in wisdom teeth that are halfway and are a gateway for bacteria. Pain, discomfort, difficulty opening the mouth, feeding difficulties are common. Given this problem, the dentist first controls infection by prescribing antibiotics and mouthwash. Everything can return to normal quickly, but if the infection tends to repeat two or three times, it is preferable to perform the extraction of wisdom teeth. Other possible problems, the wisdom teeth can cause the displacement of teeth or infect adjacent teeth.

If there are tooth decay

Because of its atypical morphology, treatment of caries in the wisdom teeth can cause problems. Given the increased risk of recurrence, extraction is a very good option.

As a precaution

The extraction of wisdom teeth as a preventive measure is subject to discussion. Some experts point out that there is no evidence that this operation avoid recurrence or onset of orthodontic problems late in the incisors. However regular monitoring of the evolution of wisdom teeth is recommended.


Any dentist can remove a wisdom tooth. But in practice, it is usual to resort to a specialist in oral surgery because it can be a delicate operation. Typically this intervention requiring medication: for six days antibiotic and anti-inflammatory to reduce edema. The extraction can be performed under local or regional anesthesia. There are very few cases where surgery is recommended under general anesthesia, which involves hospitalization. Given the risks associated with general anesthesia, its use should be truly exceptional. The anesthetic can be injected through very fine needles. According to the arrangement and number of teeth which need to be removed, the extraction can be performed once or twice. If the teeth to be extracted pose few problems, you may delete them all at once. But generally preferred to do it in two stages. Thus patients experience less difficulty feeding. This intervention, although painless, can impress the patient. The extraction process requires a great expenditure of energy by the dentist. After the disappearance of these useless molars food must be soft, like yogurt and purees.
