This represents the intraosseous or submucosal retention of a fully developed tooth, beyond its normal eruption period, without the possibility or tendency to erupt. Impacted teeth can also exist at advanced ages, even if the permanent tooth eruption process has long been completed.
Frequency of tooth impaction
It is most frequently encountered in permanent teeth and rarely in temporary teeth. Most commonly, lower wisdom teeth, upper canines, upper wisdom teeth, and upper and lower second premolars are left in inclusion. Inclusion can also affect central incisors, upper, exceptionally, the 6-year molar, the 12-year molar, and the lower canine.
Symptomatology
Whether or not it's specific. Most of the time, the clinical signs of dental impaction go unnoticed, potentially being discovered by chance during a radiological examination of neighbouring regions.
