If you have braces there are certain foods that should be avoided. Sticky foods, such as gum, caramel and licorice, are all foods that cannot be easily cleaned off the braces. They may lead to discoloration and decay of your teeth. As well, they may loosen the glue on the brackets, causing it to break off the tooth. Hard foods such as nuts, hard candy and pizza crusts may also damage your braces. Even though our braces are made of durable materials, such as stainless steel and ceramics, they are fragile and can be damaged by eating the wrong foods.
