Following scientific evaluations these results were obtained: abnormal size and function of the tongue can cause dentoskeleteal disorders and complications in other anatomical structures and physiological activities of the oral cavity even in absence of any other etiological factor. Neglecting this can lead to failure of orthodontic treatments and can be an important factor causing relapse. Besides, we cannot declare that the tongue volume is whether complementary to the forces or not. In conclusion, increased function because of increased tongue volume and growth can cause dental or dentoskeletal disorders.
