Occasionally, if the tooth misalignment is of a lesser amount, teeth straightening can be done “visually” using porcelain veneers and crowns, this is frequently referred to as “instant orthodontics”. In cases where teeth have been in the past heavily filled or dark-stained, the patients frequently pick this course, because the color and visual position of the teeth can be corrected at the same time.
Nowadays, with advances in aesthetic dentistry you can have teeth straightening by means of some of the more desirable aesthetic treatments such as laminate veneers &zirconium crowns, as part of a smile makeover.
Orthodontics is a field of dentistry concerned with the analysis & treatment of incorrect bite, which may well be a result of tooth irregularity, disproportionate jaw. Although removable appliances, or “plates”, headgear, expansion appliances, and many other devices can be used for teeth straightening.
