Tooth-impaction Research Articles

An impacted tooth is one which does not erupt within the planned developmental window into the dental arch. Since impacted teeth do not erupt, they are retained throughout the lifetime of the individual, unless they are surgically extracted or exposed. Due to adjacent teeth, dense overlying bone, excessive soft tissue or genetic abnormality, teeth may get impacted. The cause of the impaction is most frequently insufficient arch length and space to erupt through. That is the total length of the alveolar arch is smaller than the arch of the tooth. Wisdom teeth are often impacted because they are the last teeth in the oral cavity to erupt. Some dentists believe that the impacted teeth should be removed except for canine teeth in some cases: Canines may simply remain buried and give no further problems, so they do not require surgical intervention.
