Removable appliances such as functional appliances, retainer, headgear can be removed from your mouth. These contain wire and plastic that fits into the top of your mouth. They are usually worn full-time. They should only be removed for cleaning, unless you are otherwise advised. When it is not in your mouth it should be in its protective box. Do not click the brace in and out with your tongue as this will break the wires and increase the length of time the treatment will take.
The problem with the removable appliances is that the plastic can chip. As long as the brace still fits this is not a problem. Sharp edges can be smoothed using fine sandpaper or an emery board. If a metal component breaks or if broken plastic is uncomfortable you must telephone for an appointment and probably you will need to make a new one.
Most commonly used removable appliance is the retainer.
