Your diet modification is a must while you are getting braces treatment. You are not supposed to eat hard, sticky and crunchy food stuffs. The banned food stuffs include toffees, chocolates, pizza, burgers, pastries, chips, non veg, nuts, gajak, nuts, cakes, hard fruits & sticky food items.  All the precautions for braces treatment differs from person to person. While some people eat all of these and still maintain their brackets intact while others find totally unacceptable reasons like i was kicked by my smaller brother or was hit by a football on my face. Physical injury to the braces can worsen the situation as is evident from the look of braces.
