As a dentist I understand you have flexibility over when you work assuming you own your own practice. Has anyone tried having their office open 12 hours a day for 3-4 days a week? What are the pros and cons of doing this. Is it hard to find people willing to work these hours? How exhausting is a 12 hour working day? Is it hard to fill these days? Do people not want to go in at 7:00 PM for a cleaning on a weekday?
