Austin orthodontics: Teeth may be crowded or have gaps between them, be crooked, causing problems in the jaw, stick out too far, or not far enough. Young children should always be monitored to ensure that their upper archway is expanding as their adult teeth prepare to erupt, because intervention at age 7 or 8 often prevents many of the problems that later require braces or any need for orthodontic services. There are as many variations of orthodontic treatments as there are patients, but some of the most common approaches include realignment by using a palatal expander, space maintainers, braces, and removable appliances. The ultimate aim is to realign the teeth so that not only the patient’s appearance is improved, but a healthier mouth is created that won’t be at such a high risk for tooth decay or tooth loss, jaw problems or gum disease.
