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. Minimize sugary foods; they cause tooth decay and related problems. Nail biting, pencil and pen chewing and chewing on foreign objects should be avoided.It's important to regularly check your braces for bent or loose wires and brackets. In the event of a loose/broken wire or bracket, call our office immediately to arrange an appointment for repair.
