Wisdom Teeth Removal

Wisdom teeth removal is the extraction of your third molars — the four permanent adult teeth located in the very back of your mouth, in the upper and lower jaws. Wisdom teeth usually erupt between the ages of 17 and 21. Most people have all four of their wisdom teeth. It’s estimated that 5% to 37% of people only have some of their wisdom teeth — or in some cases, none at all.

Why do we have wisdom teeth?

Researchers believe that wisdom teeth were necessary for our ancestors, as their diet mostly consisted of hard nuts, crunchy leaves and uncooked meat. Today, however, we eat more cooked food and use forks and knives to cut our food up into smaller pieces. As a result, wisdom teeth are widely regarded as vestigial structures (parts of the human body that have become unnecessary).

What happens during wisdom teeth removal?

Once sedation medications have been given, your surgeon will administer local anesthesia to numb the teeth and gums. Impacted wisdom teeth (wisdom teeth trapped in the gums or bone) are exposed with incisions, giving your surgeon adequate access. Once the wisdom teeth are visible, your oral surgeon carefully loosens and lifts them from their sockets, cleans the areas and places stitches. In most cases, the stitches will fall out on their own in a few days.
