Teeth tend to become crooked for several reasons: crowding of teeth due to lack of space, lost teeth (which creates space in the mouth and causes the remaining teeth to tilt towards such spaces) or teeth in leaning positions that push the other teeth.

In such cases it is necessary to identify which is the cause for the teeth moving.

Once the cause is determined, corrections should be made whether by using braces or, in some cases, by changing the shape of the teeth with different materials, such as resins, veneers or porcelain crows.
