Spouses: An ideal set up for a spouse who wants to contribute but not hold down a full time position is for the spouse to learn the FD (or even dental assisting) backwards and forwards so that he or she can be used as a trainer for both existing and new staff as well as being able to fill in when an employee is absent or while there is an open position needing to be filled. A spouse can also be used to oversee finances, marketing, etc.
