Removing teeth with remaining bone support is a pretty traumatic procedure. Cat and dog tooth roots are not like conical human tooth roots and their teeth cannot be just “pulled.” They frequently need to be sectioned with drills, and bone has to be removed. Think of the human equivalent as having a wisdom tooth removed.
Removing kitty teeth with good remaining bony support to treat gingival inflammation or infection is way overkill. My opinion, but it is based on my own experimental animal clinical experience.
