Eruption occurs after the [[Tooth - Anatomy & Physiology#Crown|crown]] has fully formed (prior to complete [[Tooth - Anatomy & Physiology#Root|root]] formation). It provides the space required for [[Tooth - Anatomy & Physiology#Root|root]] completion. The epithelial covering is continuous with gums after eruption. Erosion (wear) removes the epithelium. The 'toothless' gene stops eruption. | Eruption occurs after the [[Tooth - Anatomy & Physiology#Crown|crown]] has fully formed (prior to complete [[Tooth - Anatomy & Physiology#Root|root]] formation).
