When a young permanent tooth is injured or develops deep decay before its root has finished growing, standard root canal treatment is difficult because the root tip is still open. Apexification and apexogenesis are specialised procedures designed for exactly this situation.
Apexogenesis preserves healthy pulp tissue so the root can continue to grow and mature naturally. Apexification, used when the pulp can no longer be saved, encourages a hard tissue barrier to form at the open root tip so the canal can then be sealed properly. Both procedures aim to keep the young permanent tooth strong and functional for life.
Children and teenagers whose young permanent teeth – usually front teeth after an injury, or molars with deep decay – have immature, still-developing roots that need specialised care to be saved.
