If you have problems with the way your jaws close together because of the way your teeth have grown crooked, then you are going to have to have some form of brace or aligner fitted in order to protect the health of your bite in the future, as well as giving you a beautiful smile. Thing is, for most people, the idea of wearing an ugly wiring diagram in their mouths for two or so years is quite a horrible thought. Well, it doesn’t have to be like that anymore in the city of London, because Invisalign goes against any concept of braces you may have conjured up in your head. Firstly it’s an aligner that comes in the shape of a gum-shield, and you change it periodically as your teeth move- and they move quickly too; the treatment lasting around 12 months. But that’s not its major selling point, nor is the fact that it is removable, so you are free to take it out whenever suits you, so long as you wear it for 22 hours a day. No, that’s not the biggest selling point either. What is is the fact that the device is made from a completely transparent plastic which means that it is virtually invisible when it is fitted into the mouth. Now that’s a selling point!!
