My daughter lost a filling and it took several weeks for us to get in to see the dentist. Dentist put my daughter on a prescribed pain medication until we got in. Finally by the appt. time for the dentist, she had developed infection of the gums & needed a root canal. I took her to an oral surgeon, he stated the clean up of the infection by the dentist was messy. He did a root canal and I got a new dentist. The infection spread and she had to be on a antibotic & pain meds for several months. She has since had 3 more root canals and has had to have the fillings in several teeth replaced. We did everything the dentist asked, kept appointments, flossed, brushed, you name it. My daugher just turned 20 years old and now has 4 root canals & suffered pain. I feel dentist was at fault.
