Tooth Eruption Definition
developing teeth emerge from the soft tissue of the jaws and the underlying mucosa into the oral cavity, where they meet the teeth of the opposing arch and perform mastication
what are the 3 phases of tooth eruption
pre-eruptive
pre-functional eruptive
functional eruptive
describe pre-eruptive phase
eruptive movements occur during crown formation and require adjustments in relation to the developing bony crypt.
describe the pre-functional eruptive phase
tooth eruption occurs along with initiation of the root development and continues until the tooth emerges into the oral cavity
describe the functional eruptive phase
teeth continue to erupt until they come into touch with the incisal or occlusal surfaces. they then undergo functional eruptive movements to compensate for jaw development and enamel occlusal wear
True or False
Eruption is a continual process that only ends with tooth loss
true
