Another reason that may lead to a dental crossbite is crowding in the maxillary arch. Permanent teeth will tend to erupt lingual to the primary teeth in presence of crowding. Side-effects caused by dental crossbite can be increased recession on the buccal of lower incisors and higher chance of inflammation in the same area.
Genetic (inheritance) factors, extra teeth, lost teeth, impacted teeth, or abnormally shaped teeth have been cited as causes of crowding. Ill-fitting dental fillings, crowns, appliances, retainers, or braces as well as misalignment of jaw fractures after a severe injury are also known to cause crowding. [26]
In 1944, Murray L. Ballard was the first to advocate for the stripping of the lower anterior teeth due to crowding in a paper published in The Angle Orthodontist.Other authors also advocated about slenderizing the teeth for next 40 years but it was not until the 1980s when John J. Sheridan's Air Rotor Stripping (ARS) technique for interproximal reduction captured significant interest.
It is a general rule to expand the maxilla to a point where the lingual cusp of maxillary molar teeth touch the buccal cusp of mandibular molar teeth. Studies done decades ago by Krebs [ 14 ] (1964), Stockfisch [ 15 ] (1969) and Linder Aronson [ 16 ] (1979) showed that about one-third to one-half of the expansion was lost before the expansion ...

The formation of teeth begins during embryonic development and is a process that is highly regulated by various signaling pathways, which, if disrupted as a result of genetic mutations or environmental factors, can lead to developmental anomalies, including hyperdontia. Tooth development begins with the formation of tooth buds in the jaw.
