Continuous tooth replacement: what can teleost fish teach us?
Biological Reviews, Volume 99, Issue 3, Page 797-819, June 2024.ABSTRACT Most tooth‐bearing non‐mammalian vertebrates have the capacity to replace their teeth throughout life. This capacity was lost in mammals, which replace their teeth only once at most. Not surprisingly, continuous tooth replacement has attracted much attention. Classical morphological studies (e.g.
