I did not know these facts prior to the tooth extraction last Monday.
Wisdom teeth, also known as "third molars," are the last teeth to emerge, usually pushing through the gums between ages 17 and 25.
Gum disease occurs when bacteria grow in the tissue supporting teeth, which can damage the tissue and cause spaces known as pockets to form around the roots. Wisdom teeth are particularly vulnerable because they are difficult to reach and keep clean. Once the bacteria get established in the mouth, other teeth may be compromised.
