In contrast, Invisalign uses a series of custom-made, clear plastic aligners to gradually move the teeth into their proper positions. These aligners are nearly invisible when worn, which makes them a popular choice for individuals who want a more discreet treatment option. Unlike braces, Invisalign aligners can be removed at any time, allowing for greater flexibility when it comes to eating, drinking, and maintaining oral hygiene. However, because they are removable, it requires a level of discipline to ensure they are worn for the recommended 20-22 hours per day.
