Crowding of the teeth is a common problem associated with the need for orthodontic care. This problem usually stems form a ciscrepancy between space available in each jaw and the size of the teeth. Many arches that appear crowed frequently do not need permanent tooth extraction. For example, a deep bite can cause significant lower anterior crowding that does not require extraction of permanent teeth. Early treatment in children using ewxpansion appliances can alleviate crowding and make room for the eruption of permanent teeth.
