Should you address Dr at beginning or DMD after a name?

When addressing a dentist with a Doctor of Dental Medicine (DMD) degree, it is generally appropriate to use "Dr." at the beginning of their name, such as "Dr. Jane Smith." The title "DMD" can be used after their name in more formal contexts, but it is not necessary in casual or direct address. Therefore, "Dr." is the preferred form when greeting or referring to them directly.
