There are many advantages to orthodontic treatment; improving the esthetics of the smile, the occlusion (bite) and the ease of maintenance, all of which help in maintaining the health of the teeth and gums.
By correcting bite problems excessive wear of the teeth can be avoided, chewing and speaking may be improved, and problems with the jaw joint may be resolved. The preventive effects of orthodontic treatment can lead to great savings with future dental work.
The most obvious reason most teens pursue orthodontic treatment is esthetics. An unattractive smile has been shown to decrease self-esteem leading to more stressful teenage years, which may affect a person for the rest of their lives.
