Infraocclusion is commonly associated with which condition?

Infraocclusion occurs when a tooth appears submerged below the height of neighboring teeth, typically because it has become ankylosed. Ankylosis means the tooth root is fused to the surrounding alveolar bone, so the tooth loses its normal periodontal ligament space and cannot follow the vertical eruption of adjacent teeth. As the surrounding bone and other teeth continue to erupt or erupt further, the ankylosed tooth remains at a lower level, creating an infraoccluded appearance. This is especially common in primary molars and can interfere with the eruption of their permanent successors. In contrast, overeruption happens when a tooth erupts beyond the opposing bite, often due to loss of the opposing tooth; that results in a supra-eruption, not submergence. A normal eruption pattern and early eruption would not inherently cause infraocclusion.
