Function 
Improved masticatory (biting/incising) function. When we align and interdigitate the teeth appropriately, eating no longer is a task…this can relieve stressed musculature and balance jaw joint (TMJ) function.
Oral Hygiene
Aligning the teeth can also facilitate brushing and flossing. Poor oral hygiene can lead to periodontitis, which can lead to tooth loss and has been linked to heart disease!
Aesthetics and Self-Esteem
Crooked or spaced teeth can cause psychological strife and low self-esteem. Kids can be brutal when it comes to the relentless taunting of another with a disfigured smile! Did you know that studies have shown attractive people to earn 10-15% more than those thought of as unattractive. Aligning the teeth yields the great smile for which you've always yearned…and improving the occlusion (bite) gives stability to that great result and minimizes the need for full-time retainer wear when the patient stops growing!
Age Beautifully
Certain treatment plans and proper timing of those plans can render gorgeous, broad smiles that support the soft tissue in a more youthful way as we age.
