Extraction of wisdom teeth
It might get narrow for those which come last. This is also true for teeth, especially at the age of 16-20, as soon as the so called wisdom teeth erupting in the back parts of the lower- and upper jaw. Very frequently there is a lack of space because the jaw is fully occupied by other teeth.
The consequence: The tooth gets stuck in the jaw, partly or completely. This can cause infections. There also might be cystis (hollow space filled with liquid) around the crown of the wisdom tooth.
The molar next to the wisdom tooth can be damaged as the resorption of tooth and the substance of th e bone is a natural feature of every tooth- otherwise there would be no breakthrough of new teeth and dissolution of baby teeth.
The tooth located next to the wisdom tooth is one which will remain so it has to be preserved. Eventually, it can lead to malposition if teeth are relocated due to the lack of space.
What kind of diagnostics makes sense?
In most cases an X-ray in the form of a panoramic layer radiograph (PSA)is enough besides the clinical diagnostics.
If there are any doubts about the location of the teeth, e.g. in relation to the nerve conduit, a tomogram on the second layer will be necessary, e.g. by DVT (digital volume tomography).
What kinds of risks have to be considered?
Besides the normal risks at an operation, e.g. like secondary haemorrhage, disturbances in the wound healing, infections, the dangers of fractions of the jaw and damages to the nerves can additionally occur at the extraction of wisdom teeth. Fractions of the jaw are very seldom and occur in the rarest cases during the procedure. More frequent are impacts of forces after the procedure - e.g. at doing sports or by accidents.
Injuries of the nerves are also very rare and can involve nerves which are responsible for the inferior lip and for the taste in the area of the tongue.
The maxillary sinus can be opened in the upper jaw and easily closed again by a suture in most of the cases.
Finally, the teeth adjacent to the wisdom tooth can be damaged , if e.g. they show big fillings.
Different position to the conduit of nerves
If there are any doubts about the location of the teeth, e.g. in relation to the nerve conduit, a tomogram on the second layer will be necessary, e.g. by DVT (digital volume tomography).
