Invisalign orthodontics can be used to move any teeth that are visible in the mouth. Invisalign, or clear braces, are used to correct crowded, misaligned or rotated teeth. One of the main advantage of Invisalign is it involves the use of clear removable trays. The trays are very small, discreet and they do not interfere with speech. Clear braces can be removed prior to eating and teeth brushing causing dental hygiene to be much easier. Invisalign is very popular as an alternative to orthodontic metal wires and bands used by most orthodontists. Most Invisalign or clear braces cases can be complete in 3-9 months. Clear braces are very popular among adults who do a lot of public speaking or enter into a lot of social meetings.
