The world of orthodontics is full of unusual words and terminology. At Braces N Faces Orthodontics in Geelong and Hoppers Crossing, we use these words every day so we're familiar with what they mean. However, for those who require braces for their teeth, they might wonder about some of the words we use. For that reason we've provided a list of words and expressions you might come across during a session with one of our orthodontists.
