You are allowed to eat almost everything except chewing gum. You may ask yourself: « Why not gum – I like it and all my friends who wear braces chew it? » It is not because we want to deny you or bother you – chewing gum causes orthodontic wires to fatigue much more rapidly. If one wants to break a piece of metal without cutting it with pliers, an easy way is to continually bend the wire back and forth in the same spot. Chewing gum has this same effect on the wire. It can also remove ligatures which helps to hold the wire into the braces as well as cause wire to come out of the braces in the back. This can allow teeth to move in the wrong direction and prolong treatment.
