Most people find that their diet doesn’t change all that much when going through treatment with braces. However, there are certain categories of foods that you’ll want to avoid for the duration. For example: Hard foods, like pretzels or nuts Sticky foods, like candy or gum Chewy foods, like pizza or bagels Crunchy food, like chips or snack foods Any one of these foods could damage the brackets or the wires that make up your braces, which could delay treatment.
