Yes. Anything hard or sticky should not be eaten during orthodontic treatment, or you risk breaking brackets off. If brackets are broken off the teeth, the teeth cannot be moved. This results in a longer treatment, and we like to be as efficient as possible. Chips, popcorn, taffy, gum, hard pizza crust, and many other foods can damage your braces. We give you a more extensive list, as well as other instructions on the day you get your braces.
