Are you new to the area? Maybe your dentist retired or left his practice? In any of these cases, you need to find a dentist pronto. Before you commit to the first DMD that your online search brings up, consider what you're really looking for. This means making a call (or a visit) to the dentist's office to ask a few pointed questions prior to scheduling your first appointment.
Asking about what insurance the office accepts and whether or not they are actually taking new patients are no-brainers.
