What is interceptive orthodontics?

Answer 8

An alternative to orthodontic movement, major occlusions may need to be extracted or have their crown height reduced {to prevent trauma to other teeth/soft tissue structures in mouth}

if noted early enough, primary teeth may be extracted to prevent dental interlock so small differences in growth rates of the upper & lower jaw may correct over time..
