Overeruption
In dentistry, overeruption is the physiological movement of a tooth lacking an opposing partner in the dental occlusion. Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the occlusion.
Overeruption can cause interferences in the occlusion and difficulty when constructing dentures. The alveolar bone typically overgrows, but root surfaces can be exposed to the oral environment increasing likelihood of dental caries. Overerupted teeth are often sharp due to lack of tooth wear (dental attrition) by adjacent teeth during chewing.
Overeruption is treated either by forcing the tooth back using orthodontic techniques, or by cutting the interfering part of the tooth and installing a crown.
