During the consultation before the procedure, our doctors will ask you about any medications you are currently taking. Some medicines may interfere with the sedation we give you and vice versa. We want to avoid any adverse drug interactions. After the root canal, you may be given an antibiotic if there was a previous infection, to prevent any additional infections. Prescription pain medication may be needed, but most patients will tolerate any discomfort with standard over-the-counter pain medication.
