Don't be late for your appt or you will have the appt canceled, however you can expect a 20 min wait for your appt which I have done in the past. Even if the weather is bad, the office will still not accept that as an excuse for being late. I drove for an hour this morning for kids appt only to be turned away after being 7 mins late due to traffic and snow. Guess he doesn't need my business and lost 4 patients this morning as I plan to find another dentist. Not very customer oriented and seems to pull unnecessary teeth from your child.
