Many of the appliances listed here are fixed appliances, meaning that they are not removable. It is important to avoid sticky, chewy or brittle foods with these appliances. Food items such as: caramels, taffy, gum, hard candies, ice, and gummy candies are ones to stay away from. It is a good idea to cut raw fruits and veggies (such as apples and carrots) into smaller pieces before eating. These appliances will be more effective if cared for properly.
