Forsus springs are a spring or push-rod appliance, they are used occasionally in conjunction with braces in order to help with correction of the bite.
Initially the springs may feel a little uncomfortable and rub on the cheeks, but in the same way that you have adjusted to having braces on your teeth, you will also adjust to this appliance. Use wax and warm salt water rinses to help your cheeks adjust to the new appliance in place.
What to do if the arms come undone?
If the arms come undone from each other you can usually fix this by opening your mouth quite wide and lining up the two parts of the arms with each other. You should find that the arms will quite easily slide back into each other.
If this doesn’t happen fairly easily after a couple of attempts it may mean that one of the arms is bent, which will make it difficult for the two sections to slide into each other. If this happens you can usually make it comfortable by tying each arm to the braces wire or brackets with some floss to keep it out of the way until you can get back to us to fix the problem.
If a spring portion comes out, keep it and bring it to your next appointment.
