Here are some of the facts that you should be aware of regarding wisdom teeth:
Wisdom teeth are the last of the permanent teeth to erupt. They are also called third molars.
Wisdom teeth usually appear in the late teenage years or early twenties. Most people will have four wisdom teeth. Wisdom teeth can be responsible for causing misalignment or crowding of the front teeth and for this reason some people opt to remove them.
In some cases, wisdom teeth never erupt through the gums and are referred to as impacted wisdom teeth (or impacted third molars). Impacted wisdom teeth are typically blocked from erupting due to the positioning of other teeth. If wisdom teeth remain impacted, they can cause pain and inflammation and infection may occur. In some cases, impacted wisdom teeth can cause damage to adjacent teeth. For these reasons, it is often necessary for individuals with impacted wisdom teeth to have them surgically removed. Your dentist can advise the most appropriate time for extraction.
Depending on your specific circumstances, wisdom teeth can be surgically extracted by your dentist in around 20 – 30 minutes. You’ll then need to spend some time under supervision in recovery as the sedation wears off.
