Tooth decay and disease

Accident trend of lower wisdom teeth

The lower wisdom teeth (38 and 48) appear to be the state for ongoing germ growth and theoretically should erupt at the end of growth behind the final second molars.

Commonly this eruption does not occur and so the remaining included tooth is a fault position (horizontal tooth) or finds a lack of space on the arcade because of a dental congestion.

The eruption may be incomplete or particularly long: the tooth is then included, partially covered by gum tissue, which can be a source of inflammatory reactions more or less important.

The symptoms linked to these wisdom teeth can be variable:

Fortuitous discovery on a panoramic radiograph of an included tooth, in the absence of symptoms, does not justify extraction.

Mechanical displacement of teeth of the mandibular arcade secondary to surgery after caused by the eruption of the tooth. These trips can sometimes bring minimal disturbances that can cause a dysfunction of the temporo-mandibular joint. It is not always easy to link this type of complication from an included wisdom tooth. The extraction of principle wisdom teeth after orthodontic treatment is immune to this germ problem.

Simple pericoronitus, with inflammation at the retro-molar cap. The mucuse membrane becomes the source of pain and lockjaw.

Gingivostomatitis, more or less diffuse, sometimes localized to the hemi-arcade mandibular.

Cellulitus peri-maxillary, starting point for the pericoronitus.

In all these cases, the extraction of a tooth will be indispensable.

The point of departure for dental pathology is multiple and often results in infectious complications of a local, regional or general nature.

The starting point is either a complicated dental inclusion, usually at the lower wisdom teeth, or pathology of the body by dental caries or periodontal disease.

The frequency of these infectious complications poses a real public health problem, all the more unacceptable because effective prevention is possible.

Tumor complications, which can be exhibited by the emergence of a dental cyst developed at the expense of the gum tissue of the wisdom tooth.

Nerve complications, leading to a type of nerve pain, is in fact very exceptional.

Iatrogenic complications stem from the physician’s activity, which is secondary to the extraction of wisdom teeth.

Mandibular: pain following the alveolar nerve below and / or the lingual nerve, pathological fracture of the mandibular angle

Infectious complications account for most accidents evolving from the wisdom teeth. These include:
