Orthodontics involves the diagnosis, treatment and prevention of alignment problems of your teeth or jaws. Corrective appliances such as braces and removable orthodontic appliances are used to move your teeth and bone structure into proper alignment over a period of time. Crooked or misaligned teeth not only detract from your appearance, they can be hard to clean and are at greater risk of tooth decay and disease. Orthodontic treatment can make your teeth both healthier and more aesthetically pleasing.   If you think you may need orthodontic treatment, the best place to start is by visiting your dentist. They will be able to advise you about whether you would benefit from orthodontics, and recommend a treatment plan for you.
