Incognito braces can be great options for those people who feel embarrass to use those metal braces. Yes, they play an important role in straightening teeth so that a person doesn't face a lifetime of teeth and gum problems. But that doesn't mean they aren't embarrassing and difficult to manage. In fact, metal braces can interfere with your lifestyle if you enjoy playing a band instrument with a mouthpiece or participate in sports activities or even love to eat popcorn.
