Sometimes, if the tooth malalignment is minor, you can "visually" straighten your teeth with porcelain veneers and crowns, something commonly refered to as "instant orthodontics".  In cases where teeth have been previously heavily-filled and are darkly stained, patients will often select this option, since the colour and visual position of the teeth can be corrected at the same time.

Today, with the advancements in cosmetic dentistry you can achieve straightened teeth using some of the more popular cosmetic treatments such as laminate veneers and zirconium crowns, as part of a smile makeover.

Orthodontics is a specialty of dentistry that is concerned with the study and treatment of improper bites, which may be a result of tooth irregularity, disproportionate jaw improved bite. Also removable appliances, or "plates", headgear, expansion appliances, and many other devices can be used to move teeth.
