Definition: Otognosis is a condition in which a person's teeth do not fit properly into their jaw, often causing difficulty with chewing and eating. It can be caused by a variety of factors such as malocclusion (misalignment), overcrowding of teeth, or jaw bone deformities. Treatment options for otognosis may include orthodontic treatment to straighten the teeth and improve bite alignment, oral surgery if necessary, or dental implants for more permanent solutions.
