They’re nearly invisible.
Because they’re made of a clear polymer material, they’re not nearly as noticeable as metal braces. In fact, they may go completely unnoticed to the casual observer.
Unlike metal braces, which are fixed in place an orthodontist, clear aligners can be removed the wearer. This makes brushing and flossing much easier, and they can also be removed for eating or special occasions. That said, though, they should be worn at least 20 to 22 hours each day to be effective.
They’re becoming more versatile.
With some complicated malocclusions(poor bites), braces and other orthodontic appliances may still be necessary.But innovations like added power ridges in clear aligners can more precisely control which teeth move and which don’t. This has greatly increased the number of poor bite scenarios where we can appropriately use clear aligners.
