I am used to the German system (where dental is included) and the U.S. system (where dental is separate) ... and dental insurance here is completely separate from medical insurance even though it may be issued by the same insurance carrier.
Good question, I believe my dental insurance is portable to other countries, but I will have to double check.
Sanitas has good info on their Web site, albeit not in English.

OK, I just checked the terms. Yes, dental covers you inside and outside Swissieland.
