The Invisalign is a set of invisible trays used to straighten teeth or fix gaps and overbites just as the traditional metal braces do. These are the modern day braces that children years ago would have loved to have. Invisaligns are fitted to your mouth by a dentist to align your teeth to the desired effect.
It involves seeing your dentist to be fitted and wearing a plastic tray 22 hours a day, changing them every two weeks, for 10 to 18 months. You will have to continue to see the dentist once a month to be fitted again as your teeth change position. Invisaligns are great for most situations, but cannot be used in cases that are more complicated.
