5 /5 Chris McCalla: So, I needed three root canals at the same time. We did two in one visit and the third in another. Friends and coworkers had me concerned about the pain. Dr. Geerlings could not have been more pain-free-- not what I expected! He and his staff could not have been more professional, friendly, and efficient. And when I went to the dentist for the permanent fillings, they too were impressed by his work, that all three fillings took only about 30 minutes. Hopefully your dentist sends you here-- the smoothest dental procedure Ive been through!
