I'm curious how long a kid could use one of these before needing to go get a new impression/print. Any dentists out there have a good estimate? I imagine it would only last them like 6 months at best. I can't see putting a kid through dental impressions that often even if the price tag dropped. For adults though this does sound exciting.
