Since the Angle-Case debate of the early 20th century, orthodontists have been arguing about nonextraction therapies vs. extraction treatment plans.
This is a debate that has continued for more than 100 years and probably will continue far into the future.

Reasons to extract:
1. Tooth mass – arch length discrepancy (severe crowding)

Severe crowding is the easiest of these conditions to determine.
In a growing patient, this can be manifested with impacted incisors and/or canines. Most of these cases become tooth replacement because there is not enough room for teeth to erupt.
