FAQ
Frequently Asked Questions
Wisdom teeth usually erupt between the ages of 17 and 25, hence the association with 'wisdom' and adulthood.
No, some people are born without one, some, or all of their wisdom teeth. It is a common evolutionary trait as human jaws have become smaller.
No. If they are healthy, fully erupted, correctly positioned, and can be cleaned properly, they may not need removal. Removal is typically recommended if they are impacted, causing pain, damaging other teeth, or leading to infection.
An impacted wisdom tooth is one that fails to fully emerge through the gums because it is blocked by other teeth, growing at an angle, or due to lack of space in the jaw.
