Orthodontics is the branch of dental science which deals with the normal growth and development of the body generally, jaws and teeth particularly; their variation and abnormalities and prevention and treatment of dentofacial abnormalities within accepted range of normal. Orthodontics is about more than just a pretty smile. Crooked and crowded teeth are hard to clean and maintain. This can result in tooth decay, worsen gum disease and lead to tooth loss. Other orthodontic problems can contribute to abnormal wear of tooth surfaces, inefficient chewing function, excessive stress on gum tissue and the bone that supports the teeth, or misalignment of the jaw joints. These can lead to chronic headaches and face or neck pain. Treatment by an orthodontist can be less costly than the additional care required to treat dental problems arising as a result of orthodontic problems. For most people, a beautiful smile is the most obvious benefit of orthodontics. After your braces come off, you'll feel more self-confidence and social acceptance.
