I like the idea of having the same set of teeth I have now (early twenties) for when I get old enough and my teeth drop out.
People who have lost the opportunity to get a 3d capture of their own teeth could possibly customize dentures based on the teeth of their younger siblings.
It'd be interesting to inspect the variety or sexual dimorphism of the dental sets between siblings in realtime 3D morph.
Saving teeth snapshots in a timeline would be quite useful for dentists to have.
Forensics might also get advantage of this.

Obfuscating would complicate things, but at least it'd be a workaround.
It's crazy that buySellAds hasn't taken advantage of this.
