Hello Danny P,Mobility (looseness) of teeth can be caused by traumatic occlusion or periodontal disease or both simultaneously. Whatever the reason, the cause needs to be identified and treated. Crooked teeth can be difficult to clean which will lead to periodontal disease. Crook ed teeth also cause mal-occlusion which leads to traumatic occlusion. If there is already periodontal disease present , it must be treated and stabilized first, then you need to address the crowding orthodontically. If you only have a traumatic occlusion, you will need to straighten the teeth and balance you occlusion so that cleaning will be easier and periodontal disease will be less likely to develop. Good luck in your quest for a straight, healthy non-traumatic, fully functioning smile. From the limited photo views, it looks like you could be treated using Invisalign.Douglas Jopling, DDSDallas, TX area
