The third molars, otherwise known as wisdom teeth, are usually the last teeth to erupt. Often there is little space at the rear of the jaws so there may not be enough space for them to fit into the mouth correctly. If there is not enough space available the tooth will become wedged in or impacted.
Some impacted wisdom teeth will remain hidden and buried under the gum or bone and not cause any problems, others may cause pain, infection or other problems.
The dentist may recommend early removal of one or more of your wisdom teeth to prevent any complications, future problems, or to commence orthodontic treatment. Otherwise the teeth will need to be removed when there is an existing problem such as infection.
Extraction of wisdom teeth may be easy and simple, or a surgical procedure depending on the severity of the case and position the tooth.
Surgical extractions mean that an incision will be made to open the gum to allow extraction. A small portion of the bone holding the tooth may need to be removed. The tooth may have to be divided into segments so it can be removed safely and easily. Sometimes the incision made will need to be closed with stitches, the stitches may be dissolvable and dissolve within a few days, or they may be silk which need to be removed by the dentist after 7-10 days.
