Expanders – widen your arch and create space
Expanders are used in conjunction with other types of braces in order to widen the arch and create space. This will help to ensure the upper and lower teeth fit together properly. It also creates space for teeth to move which is why expanders often precede fixed braces in an orthodontic treatment plan. Expanders tend to be used in orthodontics for children when the teeth and jaw are still developing.
