tooth eruption

the final stage of odontogenesis, in which a tooth breaks out from its crypt through surrounding tissue.


1. Passage of a tooth through the alveolar process and perforation of the gingiva.
2. A breaking out, especially the appearance of lesions on the skin.
[L. e-rumpo, pp. -ruptus, to break out]


1. the act of breaking out, appearing or becoming visible, as eruption of the teeth.
2. visible efflorescent lesions of the skin due to disease, with redness, prominence, or both; a rash.

Furthermore, there is absolutely no research evidence (as conceded in the 'learning module') to support the use of systemic analgesia to treat the subtle physiological symptoms associated with uncomplicated tooth eruption, and indiscriminate drug use may lead to risks of toxicity and mistaken dosage.
In specialized literature, there are different methods studying the development, maturity and tooth eruption for the purpose of estimating biological age from the teeth and managing an approximation to the chronological age; bearing in mind that the tendencies in the proportions of dental maturation vary with respect to the ethnic group studied and that these even vary among members of a same ethnic group, depending on the geographic distribution and environment.
