Deciduous Tooth

Eruption occurs after the crown has fully formed (prior to complete root formation). It provides the space required for root completion. The epithelial covering is continuous with gums after eruption. Erosion (wear) removes the epithelium. The 'toothless' gene stops eruption.

Permanent Tooth

The tooth migrates into the socket of the deciduous tooth on the lingual side. It increases the pressure on the deciduous tooth by increased growth. Resorption of the deciduous tooth root leads to its loosening. The deciduous tooth then sheds and the permanent tooth replaces it. Premature loss of the deciduous tooth leads to disorganised (non-occluding) permanent teeth.
