Replacement Teeth (IMAGE) Uppsala University Caption Replacement teeth (in gold) are sitting on a stack of resorption surfaces that like the plates in a cupboard, which evidences this tooth site has been replaced four times. In contrast, the other dentine units, the tooth-like odontodes (in red) and the gap-filling odontodes (in pink) that bury them, never experience basal resorption and won't be shed.
