There are many reasons why teeth need to be straightened.
For some people, the appearance of crooked teeth causes embarrassment. Bad bites can also lead to accelerated tooth wear and break down of the teeth. In severe cases, speech
and eating can be a problem.
In growing children, bad bites can lead to development of asymmetries and jaw disproportions.
Commonly, in mouths where some teeth are missing or badly worn, orthodontic treatment is required to facilitate replacement or repair of the teeth.
Finally, straight teeth and good bites make oral hygiene easy promoting the health of the teeth and gums.
