Thanx to the Dctrs on RealSelf for their helpful replies to my questions. I want to know if the impression/mold of my original teeth belongs to me. I would like to keep the original mold because if something happened to my crowns in the future, a dentist would be able to see what my original teeth were like and make new sets from the original mold/impression. We travel a lot and live in different countries for a period of time, so I may not be able to see my original dentist. Thanks in advance.
