Your dentist may have discussed the benefits of having healthy teeth and proper jaw alignment with you. Crooked and crowded teeth are harder to clean and maintain. This can result in tooth decay, 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. Treatment by an orthodontist can be less costly than the additional care required treating dental problems that result from orthodontic problems.
