Failure of permanent teeth to erupt without any known cause is a rare incident. We report a case of multiple unerupted permanent teeth and make an effort to predict all possible causes of non-eruption of permanent teeth clinically and radiographically. It is essential to diagnose and treat eruption disturbances as early as possible because treatment at a later stage is usually more complicated due to the tendency of malocclusion to increase with time and reduced ability of remaining dentition to adjust.
