Your patient has a dentist in another state, and that is the content
A seasonal patient is sharing their mouth between two practices in two states, and almost nobody publishes anything useful about how that arrangement works.
Somebody who spends the warm months up north has a hygienist there and a hygienist here, two sets of radiographs and two treatment plans that have never met each other.
The arrangement produces a set of questions nobody answers on camera. Who should do which cleaning, how records move between two offices, whether a crown started somewhere else in April can be seated in Palm Beach County in November.
Answer them plainly and you become the practice that understands the arrangement rather than the one that acts insulted by it. Patients here are used to being made to feel disloyal for having a dentist in two places, and they notice when somebody stops doing that.
Say what you need from the other office and when to ask for it. A patient who requests their records in September walks into your chair in November with the work already scoped instead of spending the first visit on paperwork.
