Invisalign uses a series of precisely made sequential retainers. The invisalign system is able to gently nudge your teeth from the starting position to the preferred end position in a number of stages. Depending on the complexity, the number of retainers can vary.
The benefits of Invisalign are that the system is almost invisible, is comfortable and also removable. This means that you are able to take the retainers out to eat and clean your teeth. Most importantly your appearance will barely change which means that you can carry on with your life as before while the treatment is occurring.
