Had a root canal this am on a back molar. This dentist uses space-age equipment. Standing X-Ray machine taking a circular 3-dimensional x-ray like an MRI or CT Scan, a digital X-Ray where the technician never had to go out of the room, a Wand to administer anaesthetic instead of a syringe (no pain at all), used a microscope to look inside the tooth while he poked around, used a rubber mouthpiece so I didn't have to stretch my mouth wide open and it took him onle 1 hour to do the complete job. I go back next week for the final filling. Best dentist I ever went to.
