The most I have ever waited to get a dentist appointment was a week after calling for an appointment.
When I broke my arm, there was a 2 hour wait. At the time I didn't know it was broken otherwise I'm sure I would have been moved up. I thought it was just a pulled muscle and went home. I went to the walk in clinic the next day, was sent for xrays and found out my arm was broken. Total cost to me? $12 for the sling.
