Where do dentist work?
A majority work in offices they own, or own with other dentists. Some dentist work in private offices of other dentists. The government employs dentist for the Indian Health Service and the branches of the Military. Some also work for public health clinics or in dental schools teaching.
If a dentist takes on another dentist's practice is he responsible for their work and fees already paid?
If work has been done and paid for, the new dentist is not responsible for it, since that work was finished by a previous dentist. If the work was paid for but not completed, then the new dentist must finish the work and take joint responsibility for it. if it was paid for but not begun, then it is a new job passed straight to him.
