For most situations, common sense will tell you what to avoid. Hard foods, sticky foods and foods high in sugar must be avoided. Hard foods can break or damage wires and brackets. Sticky foods can get caught between brackets and wires. Minimise sugary foods; they cause tooth decay and related problems. Nail biting, pencil and pen chewing and chewing on hard objects (e.g. opening sports bottles with your teeth, chewing on plastic rulers, leather straps etc. ) should be avoided. In general it is wise to remember to be gentle and careful with your brace – always.
Fewer breakages and better care with food & drink means your teeth will move faster and will look better when the braces are eventually removed.
In general, it is best to avoid all snacking between meals – even if you plan to brush your teeth immediately afterwards. No matter how well you brush, some bits of sugar will be left to cause damage to the teeth. It is particularly important to avoid eating within an hour of going to bed.
