The condition in which orthodontically treated teeth gradually move back to their original position is called Relapse. This happens when the treatment is either done hastily or if there is no retention plate given after removing the braces. Veneers as an option can be considered in case you are in a hurry to get them straightened or in case you do not wish to undergo braces again. But mind you, braces is the preferred choice of treatment.
