Invisalign is a method of moving teeth using a series of clear, virtually invisible, removable aligners. The aligners are made of smooth, comfortable plastic that gradually and gently shifts your teeth into place. The disposable aligners are worn all day and are only removed when eating or drinking. There are no wires or brackets to tighten. Like braces, Invisalign can be used in most situations, and most people are good candidates to use this technology. Consider Invisalign to straighten your teeth without the aesthetic compromise of brackets and wires. Invisalign can be used to address crooked teeth, uneven teeth, spaces between the teeth, and minor over and under bites. The process of fitting Invisalign is relatively easy. Impressions and photographs are taken and sent to the laboratory, which uses a special computer program to calculate all the steps needed to adjust the position of the teeth.
