Endodontic treatment has now been completed. You'll need a trusted drive home if you've been sedated. No need to have a driver for nitrous oxide sedation. We'll make sure the nitrous is out of your system by turning if off well in advance. The root canal system has been permanently sealed. However, the outer surface is sealed with a temporary restoration. A follow-up restoration must be placed to protect your tooth against fracture and decay. Please telephone your restorative dentist for an appointment. A complete report of treatment will be sent to your restorative dentist. Included in your treatment is a follow-up examination to evaluate the progress of healing. This appointment will require only a few minutes and no additional fee will be charged for the first check-up visit. Please call for an appointment during the following month.
