Angels,

When a tooth is extracted, it is imperative to remove the tooth in its entirety.... this includes every bit of tooth structure including the roots. It is also imperative to remove the periodontal ligament that surrounds the root structure as this ligament is a chronic source of infection if it is left in the bone. And it is also imperative to remove all other diseased tissue and diseased bone as they too will be a chronic source of infection if they are left behind.

Ninety nine+ percent of the time, there is no reason not to perform a complete and thorough tooth extraction.
