Spacing between teeth are another common problem associated with the need for orthodontic care. Like crowding, spacing may be related to a tooth-to-jaw size disharmony. Gum tissue attachment called “frenum” is also a common cause of spacing between the front teeth. Excessive overlapping of the front teeth as well as protruding front teeth may lead to spacing. Other contributing factors include missing or impacted teeth and sometimes the teeth are too narrow in width.
