Orthodontics is the specialty of dentistry, which deals with the arrangement of teeth in dental arches and the guidance of the jaws in harmonious positions between them, with the aim of restoring the proper functioning of the mouth and the aesthetics of the face.

Orthodontic problems may be due to hereditary or environmental factors or a combination of the above. The size of teeth and jaws and the relationships between them are characteristics that are inherited from parents to children.

Various habits of children are often the causes of abnormalities in the development of the teeth and mouth. Such habits include teeth grinding, tongue pressure, biting the lower lip, nails or foreign objects (pencils, erasers, etc.), one-sided chewing, finger sucking, etc.
