Braces are needed when there is a cosmetic concern and a bite issue. For example, if teeth are misaligned and becoming loose from biting down, that is a reason to move the teeth into a better place. Also, more simple things such as closing a space is a reason to get braces. Other signs that braces are recommended are if you have a crossbite, underbite, crowding, traumatic occlusion, jaw pain, difficulty breathing or snoring at night, or simply want to improve your smile and how you feel.
