With Cfast, extractions are not required. Space to relieve crowding is gained by gently easing the contact points between the teeth using a polishing strip. This creates a very small space between the teeth that allows them to move and slide past each other into a more ideal position.
The conservative removal of enamel between the teeth using these special polishing strips is very safe and a well-recognised procedure in dentistry and does not damage the teeth.
In rare circumstances the dentist may advocate the removal of a front tooth in the lower jaw if there is extreme crowding. However, if this is required you will be consulted fully and further special investigations will be carried out before proceeding.
