Eating with braces, what foods are good and what foods to avoid. Your diet is extremely important when it comes to braces. Hard, sticky, crunchy and chewy foods can damage braces which leads to more appointments to fix then and ultimately lengthening your treatment duration. If changing your diet is not an option, Invisalign clear braces may suit you better. Invisalign is removable, so you can pop them out to eat, so you can eat whatever type of food you want!
