− | There is a reciprocal inductive interaction between the oral epithelium and mesenchyme precursors. The mesenchyme forms the tooth, it has labile differentiative properties but stable morphogenic properties. Tooth formation starts at the [[Enamel Organ#Crown|crown]] and progresses towards the [[Enamel Organ#Root|root]]. The tooth does not acquire full length until the crown has emerged. Tooth growth is appositional. | + | There is a reciprocal inductive interaction between the oral epithelium and mesenchyme precursors.
