 Ankylosis

Tooth ankylosis is the fusion of the tooth to the bone, preventing the tooth from erupting. This can happen in both primary ("baby") teeth and permanent teeth, and may occur at any stage during development or eruption. The cause of this condition is still uncertain. Theories include trauma and heredity. An exam and x-ray are the main diagnostic methods for determining ankylosis. Some cases require surgical extractions for orthodontic and functional purposes.
