Clear braces are a discreet option for straightening teeth that are less noticeable than traditional metal braces. There are two main types of clear braces - fixed braces which are bonded onto the teeth using clear brackets and wires, and removable aligners that are switched out every 7-10 days to gradually shift the teeth. Clear braces make teeth straighter with less self-consciousness than metal braces and are well-suited for adults with minor misalignment.
