Common questions
How long does socket remodelling take, and how does that help estimate timing?+
Bone infilling of an empty socket progresses over weeks to months, so a socket that is still sharp-edged and open indicates loss shortly before death, a partially filled socket indicates weeks of healing, and a fully smoothed, remodelled ridge indicates loss long before death.
Why does distinguishing antemortem from postmortem tooth loss matter in casework?+
Antemortem loss with healing evidence reflects the person's dental history and can support identification against known dental records, while postmortem loss, for example from trauma or scavenging, shows no healing response and must not be mistaken for a preexisting gap.
