Definition and Terminology
- Overeruption, hypereruption, supraeruption, supereruption, or continuous eruption are all terms used to describe the physiological movement of a tooth lacking an opposing partner in the dental occlusion.

Pathophysiology and Factors
- Teeth lacking an opposing tooth have a tendency to erupt out of the line of occlusion due to the lack of opposing force and the natural eruptive potential of the tooth.
- Not all teeth lacking an opposing tooth overerupt, particularly in the long term.
- Unopposed upper jaw molars are more prone to overeruption compared to unopposed lower jaw molars.
- Overeruption is more severe in young people and those with periodontal issues.
- The changes associated with overeruption are most visible in the first year after the loss of the opposing tooth.

Consequences and Complications
- Overeruption can cause interferences in the occlusion and difficulties in constructing dentures.
- The alveolar bone typically overgrows, but the exposed root surfaces increase the likelihood of dental caries.
- Overerupted teeth often become sharp due to the lack of tooth wear from adjacent teeth during chewing.

Treatment Options
- Tooth replacement is not recommended as the primary therapy for overeruption.
- Overeruption can be treated by forcing the tooth back using orthodontic techniques or by cutting the interfering part of the tooth and installing a crown.

Related Concepts
- The Dahl effect is related to overeruption and refers to the changes in tooth position and occlusion caused by the placement of an interocclusal appliance.
