Tooth impaction refers to the failure of teeth to erupt into the mouth within the normal time, where the failure of outburst appears to originate from mechanical blocking. Tooth impaction may result from a number of local causal factors. These include arch length discrepancy, ectopic positioning of the teeth, presence of supernumerary teeth, mucosal or bony barriers, and retained deciduous teeth.
