Is there a saying in Feng Shui that wisdom teeth are pulled out?

No, first of all, people in the past didn't have the consciousness of extracting wisdom teeth.

Secondly, wisdom teeth are supernumerary teeth, and most people will grow. If there is any feng shui, I think it is: any irreversible damage to body tissues and organs, such as tattoos or ear piercing, will have a certain turning point in luck before the injury.
