These are worn full time to begin with and there are no exceptions to these instructions, unless your orthodontist specifically tells you otherwise.
If the retainer is lost, breaks or does not fit properly, you must contact us immediately to prevent unwanted movement of your teeth, which cannot be reversed. Whenever you remove your retainers, such as when you are eating or playing sports, or on instruction by the orthodontist, you must store them safely in their protective box.
Do not get into the habit of clicking the retainer in and out with your tongue as this can cause it to break. Clean your retainers using a toothbrush and cold water, or use cleansing tablets.
