I’ve had almost every type of appliance available stuffed in my mouth at some stage or another.
At the end of the day, nothing beats the look – and feel –of a classic old-fashioned interlandi headgear. I’ve had the cervical – which is good, but the big one works best.
Lately I have a top Hawley retainer and an interlandi, which is wonderful for adventures, and wonderful for taking out and hiding in the drawer when the fun is over.
