Invisalign Las Vegas is delicate plastic trays that can be easily cracked, eroded, or even lost. And while braces are fastened to the teeth, so they can't be lost, sometimes the metal wires snap or brackets slide. To counter this, patients need to be careful in what they eat and do. This will show how your teeth will move after each tray, and you will basically see the shifting of your teeth from beginning to end result.
